Enterprise Server Overview
Sun GlassFish Enterprise Server administration includes many tasks such as deploying
applications, creating and configuring domains, server instances and resources; controlling
(starting and stopping) domains and server instances, managing profiles and clusters,
monitoring and managing performance, and diagnosing and troubleshooting problems.
Enterprise Server provides a Java EE compatible server for the development and deployment of
Java EE applications and Java Web Services. Key features include scalable transaction
management, container-managed persistence runtime, performant web services, clustering,
high availability, security, and integration capabilities.
Enterprise Server Overview and Concepts
This section contains the following topics:
■
■
Enterprise Server Overview
You can configure and monitor Enterprise Server instances and clusters securely and remotely,
from a web-based central administration console. The command line interface (CLI) can be
used to script and automate processes. A stable JMX API is made available to programmatically
monitor the server, query configuration and change configuration data. Monitoring is
supported through JMX and SNMP interfaces. Monitoring level may be varied dynamically
from OFF to LOW and high, changing the amount of information that is collected.
You can configure and optimize Enterprise Server for a particular type of use by specifying the
appropriate profile when you create the application server domain.
23
Enterprise Server Overview and Concepts
Enterprise Server includes the Metro web services stack (http://metro.dev.java.net). Metro
implements important WS-* standards and WS-I standardized interoperability profiles in
order to assure interoperability between Java and .NET web services.
Enterprise Server includes the implementation of Java Business Integration (JBI) specifications.
JBI is a Java standard for structuring business systems according to a Service-Oriented
Architecture (SOA).
Tools for Administration
The Enterprise Server provides the following administration tools and APIs:
■
■
■
Admin Console
The Admin Console is a browser-based tool that features an easy-to-navigate interface and
online help. The administration server (also called the Domain Administration Server or DAS)
must be running to use the Admin Console. To, launch the Administration Console, you must
know the administration server hostname and port number. When the Enterprise Server was
installed, you chose a port number for the server, or used the default port of 4848. You also
specified a user name and master password.
To start the Admin Console, in a web browser type:
http://hostname:port
For example:
http://kindness.sun.com:4848
If the Admin Console is running on the machine on which the Enterprise Server was installed,
specify localhost for the host name.
On Windows, start the Enterprise Server Admin Console from the Start menu.
The installation program creates the default administrative domain (named domain1) with the
default port number 4848, as well as an instance separate from the domain administration
server (DAS). After installation, additional administration domains can be created. Each
domain has its own domain administration server, which has a unique port number. When
specifying the URL for the Admin Console, be sure to use the port number for the domain to be
administered.
24
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Enterprise Server Overview and Concepts
If your configuration includes remote server instances, create node agents to manage and
facilitate remote server instances. It is the responsibility of the node agent to create, start, stop,
and delete a server instance. Use the command line interface (CLI) commands to set up node
agents.
Command-line Interface (asadmin Utility)
The asadmin utility is a command-line interface for the Sun GlassFish Enterprise Server. Use
the asadmin utility and the commands associated with it to perform the same set of
administrative tasks offered by the Admin Console. The default installation root directory on
Solaris is /opt/SUNWappserver.
To start the asadmin utility, go to the as-install/bin directory and enter:
$ ./asadmin
To list the commands available within asadmin:
asadmin> help
It is also possible to issue an asadmin command at the shell’s command prompt:
$ asadmin help
To view a command’s syntax and examples, type help followed by the command name. For
example:
asadmin> help create-jdbc-resource
The asadmin help information for a given command displays the UNIX man page of the
command. These man pages are also available in HTML and PDF format in the Sun GlassFish
JConsole
JConsole is used to monitor the Sun GlassFish Enterprise Server. You can use either the
JConsole remote tab, or the advanced tab to connect to the Enterprise Server.
■
Remote Tab: identify the username, password, administration server host, and JMS port
number (8686 by default), and select Connect.
■
Advanced Tab: identify the JMXServiceURL as
service:jmx:rmi:///jndi/rmi://host:jms-port/jmxrmi and select Connect. The
JMXServerURL is printed in the server.log file as well as output in the command window of
the domain creation command.
Chapter 1 • Enterprise Server Overview
25
Enterprise Server Concepts
Enterprise Server Concepts
The Enterprise Server consists of one or more domains. A domain is an administrative
boundary or context. Each domain has an administration server (also called Domain
Administration Server or DAS) associated with it and consists of zero or more standalone
instances and/or clusters. Each cluster has one or more homogeneous server instances. A server
instance is a single Java Virtual Machine (JVM) that runs the Application Server on a single
physical machine. Server instances (whether standalone or clustered) in a domain can run on
different physical hosts.
This section contains the following topics:
■
■
■
■
■
■
Domain
A domain is a group of instances that are administered together. However, an application server
instance can belong to just one domain. In addition to the administration boundary, a domain
provides the basic security structure whereby different administrators can administer specific
groups (domains) of application server instances. By grouping the server instances into separate
domains, different organizations and administrators can share a single Enterprise Server
installation. Each domain has its own configuration, log files, and application deployment areas
that are independent of other domains. If the configuration is changed for one domain, the
configurations of other domains are not affected.
The Sun GlassFish Enterprise Server installer creates the default administrative domain (named
domain1). It also creates an associated domain administration server (named server). You
must provide the administration server port number. The default administration server port is
4848. The installer also queries for the administration username and master password. After
installation, additional administration domains can be created.
Domain Administration Server (DAS)
Each domain has its own Domain Administration Server (DAS) with a unique port number.
The Admin Console communicates with a specific DAS to administer the associated domain.
Each Admin Console session allows you to configure and manage the specific domain.
The Domain Administration Server (DAS), is a specially-designated application server instance
that hosts the administrative applications. The DAS authenticates the administrator, accepts
requests from administration tools, and communicates with server instances in the domain to
26
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Enterprise Server Concepts
carry out the requests. The DAS is sometimes referred to as the admin server or default server. It
is referred to as the default server because it is the only server instance that gets created on Sun
GlassFish Enterprise Server installation and can be used for deployments. The DAS is simply a
server instance with additional administration capabilities.
Each Admin Console session allows you to configure and manage a single domain. If you
created multiple domains, you must start an additional Admin Console session to manage the
other domains. When specifying the URL for the Admin Console, be sure to use the port
number of the DAS associated with the domain to be administered.
Usage Profiles
Every administrative domain is associated with a usage profile, which identifies the capabilities
of that domain. Enterprise Server provides the following profiles:
■
Developer: Use this profile if you are running your domain in a development environment
and if your applications do not need the NSS keystore or clustering features, such as load
balancing, and session persistence.
■
Cluster: Use this profile if you need to create clusters but do not require the high-availability
database (HADB) or the NSS keystore.
■
Enterprise:: Use this profile if you need HADB and NSS. This profile is usable only if you
install HADB and NSS separately or if you install Enterprise Server as part of enterprise
offerings, such as Java Enterprise System (JES). For information on how you can use the
enterprise profile with Enterprise Server, see Using the Enterprise Profile
The domain provides a preconfigured runtime for the user applications. Usage profiles
facilitates the distinction between the Application Server binaries and the runtime
configuration. Profiles enable you to use the same installation of Enterprise Server to create
different domains with profiles that suit specific needs. For example, a developer may want to
use the Enterprise Server to get to know the latest Java EE specifications. This developer does
not need stringent security settings. Another user who wants to deploy applications in a
production environment needs an inherently secure environment.

Cluster
A cluster is a named collection of server instances sharing the same set of applications,
resources, and configuration information. A server instance can belong to exactly one cluster. A
cluster facilitates server instance load-balancing through distribution of a load across multiple
machines. A cluster facilitates high availability through instance-level failover. From an
administrative perspective, a cluster represents a virtualized entity in which operations on a
cluster (e.g. deployment of an application) act on all instances that make up the cluster.
Horizontal scaling is achieved by adding Enterprise Server instances to a cluster, thereby
increasing the capacity of the system. It is possible to add Enterprise Server instances to a cluster
without disrupting service. The HTTP, RMI/IIOP, and JMS load balancing systems distribute
requests to healthy Enterprise Server instances in the cluster.
High Availability - Availability allows for failover protection of Enterprise Server instances in a
cluster. If one application server instance goes down, another Enterprise Server instance takes
over the sessions that were assigned to the unavailable server. Session information is stored
using the session replication feature or by using the high-availability database (HADB). HADB
supports the persistence of HTTP sessions and stateful session beans.
Node Agent
A lightweight agent (e.g. hosting a JMX runtime only) is required on each node in the domain
to facilitate remote lifecycle management of instances. Its primary purpose is to start, stop, and
create server instances as instructed by the DAS. The Node Agent also acts as a watchdog and
restarts failed processes. Like the DAS, the Node Agent should only be required for certain
administrative operations and should not be expected to be highly available. However, the Node
Agent is an “always on” component, and must be configured to be started by the native O/S
node bootstrap (e.g. Solaris/Linux inetd, or as a Windows service). A Node Agent is not
required for the DAS.

Enterprise Server Concepts
Server Instance
The server instance is a single Java EE compatible Java Virtual Machine hosting an Enterprise
Server on a single node. Each server instance has a unique name in the domain. A clustered
server instance is a member of a cluster and receives all of its applications, resources, and
configuration from its parent cluster; ensuring that all instances in the cluster are
homogeneous. An unclustered server instance does not belong to a cluster and as such has an
independent set of applications, resources, and configuration. The following figure shows an
application server instance in detail. The application server instance is a building block in the
clustering, load balancing, and session persistence features of the Enterprise Server.
FIGURE 1–1 EnterpriseServer Instance
The Sun GlassFish Enterprise Server creates one application server instance, called server, at
the time of installation. For many users, one application server instance meets their needs.
However, depending upon your environment, you might want to create one or more additional
application server instances. For example, in a development environment you can use different
application server instances to test different Enterprise Server configurations, or to compare
and test different application deployments. Because you can easily add or delete an application
server instance, you can use them to create temporary sandbox area for experimentation
purposes.
In addition, for each application server instance, you can also create virtual servers. Within a
single installed application server instance you can offer companies or individuals domain

names, IP Addresses, and some administration capabilities. For the users, it is almost as if they
have their own web server, without the hardware and basic server maintenance. These virtual
servers do not span application server instances. For more information about virtual servers,
In operational deployments, for many purposes you can use virtual servers instead of multiple
application server instances. However, if virtual servers do not meet your needs, you can also
use multiple application server instances. On stopping, application server instance stops
accepting new connections, then waits for all outstanding connections to complete. If your
machine crashes or is taken offline, the server quits and any requests it was servicing may be
lost.

Creating a Domain
Domains are created using the create-domain command. The following example command
creates a domain named mydomain. The administration server listens on port 5000 and the
administrative user name is admin. The command prompts for the administrative and master
passwords.
$ asadmin create-domain --adminport 5000 --adminuser admin mydomain
To start the Admin Console for mydomain domain, in a browser, enter the following URL:
http://hostname:5000
In Enterprise Server 9.1, every domain has a profile associated with it. For information on
creation. Use the --profile option with the create-domain command to specify a profile for
the domain. If you do not use the --profile option to explicitly specify a profile, the default
profile is associated with the domain. The AS_ADMIN_PROFILE variable in the asadminenv.conf
file defines the default profile.
Chapter 1 • Enterprise Server Overview
31
Basic Enterprise Server Commands
Caution – Do not create an enterprise domain unless you have HADB and the Network Security
Services (NSS) keystore. You will not be able to start an enterprise domain unless you have
HADB and NSS.
For the preceding create-domain example, the domain’s log files, configuration files, and
deployed applications now reside in the following directory:
domain-root-dir/mydomain
To create the domain’s directory in another location, specify the --domaindir option. For the
Deleting a Domain
Domains are deleted using the asadmin delete-domain command. Only the operating system
user (or root) who can administer the domain can execute this command successfully. To delete
a domain named mydomain, for example, type the following command:
$ asadmin delete-domain mydomain
Listing Domains
The domains created on a machine can be found using the asadmin list-domains command.
To list the domains in the default domain-root-dir directory, type this command:
$ asadmin list-domains
To list domains that were created in other directories, specify the --domaindir option.
Starting the Domain
When starting a domain, the administration server and application server instance are started.
Once the application server instance is started it runs constantly, listening for and accepting
requests. Each domain must be started separately.
To start a domain, type the asadmin start-domain command and specify the domain name.
For example, to start the default domain (domain1), type the following:
$ asadmin start-domain --user admin domain1
If there is only one domain, omit the domain name. For the full command syntax, type asadmin
help start-domain. If the password data is omitted, you are prompted to supply it.
32
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Basic Enterprise Server Commands
Starting the Default Domain onWindows
From the Windows Start Menu, select Programs -> Sun Microsystems -> Enterprise Server ->
Start Admin Server.
Stopping the Domain
Stopping a domain shuts down its administration server and application server instance. When
stopping a domain, the server instance stops accepting new connections and then waits for all
outstanding connections to complete. This process takes a few seconds because the server
instance must complete its shutdown process. While the domain is stopped, the Admin Console
or most asadmin commands cannot be used.
To stop a domain, type the asadmin stop-domain command and specify the domain name. For
example, to stop the default domain (domain1), type the following:
$ asadmin stop-domain domain1
If there is only one domain, then the domain name is optional. For the full syntax, type asadmin
help stop-domain.
Consult the Admin Console online help to stop the domain through the Admin Console.
Stopping the Default Domain onWindows
From the Start menu select Programs -> Sun Microsystems -> Enterprise Server-> Stop Admin
Server.
Restarting the Domain
Restarting the server is the same as restarting the domain. To restart the domain or server, stop
and start the domain.
Creating a Cluster
A cluster is created using the create-cluster command. The following example creates a
cluster named mycluster. The administration server host is myhost, the server port is 1234, and
the administrative username is admin. The command prompts for the administrative
passwords.
$ asadmin create-cluster --host myhost --port 1234 --user admin mycluster
Chapter 1 • Enterprise Server Overview
33
Basic Enterprise Server Commands
For the full syntax, type asadmin help create-cluster.
Starting a Cluster
A cluster is started using the start-cluster command. The following example starts the
cluster named mycluster. The command prompts for the administrative passwords.
$ asadmin start-cluster --host myhost --port 1234 --user admin mycluster
For the full syntax, type asadmin help start-cluster.
Stopping a Cluster
A cluster is stopped using the stop-cluster command. The following example stops the cluster
named mycluster. The command prompts for the administrative passwords.
$ asadmin stop-cluster --host myhost --port 1234 --user admin mycluster
myhost is the administrative server host, 1234 is the administrative port, admin is the
administrative username.
For the full syntax, type asadmin help stop-cluster. When a cluster is stopped, all the server
instances in the cluster get stopped. A cluster without instances cannot be stopped.
Creating a Node Agent
A node agent is created using the create-node-agent command. The following example
creates node agent named mynodeagent. The administration server host is myhost, the
administration server port is 1234, and the administrative username is admin. The command
normally prompts for the administrative passwords; however, if the --savemasterpassword
option is not specified or false, the command does not prompt for the administrative
passwords.
$ asadmin create-node-agent --host myhost --port 1234 --user admin mynodeagent
For the full syntax, type asadmin help create-node-agent.
Starting a Node Agent
A node agent is started using the start-node-agent command and specifying the node agent
name. For example, to start the node agent mynodeagent, type the following:
$ asadmin start-node-agent --user admin mynodeagent
34
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008

name. For example, to stop the node agent mynodeagent, type the following:
$ asadmin stop-node-agent mynodeagent
For the full syntax, type asadmin help stop-node-agent.
Starting an Instance
A server instance is started using the start-instance command. The following example starts
the server instance named myinstance. The command prompts for the administrative
passwords.
$ asadmin start-instance --host myhost --port 1234 --user admin myinstance
The administrative server host is myhost, the administrative port is 1234, the administrative
username is admin. The server instance myinstance can be clustered or standalone.
For the full syntax, type asadmin help start-instance.
Stopping an Instance
A server instance is started using the stop-instance command. The following example stops
the server instance named myinstance. The command prompts for the administrative
passwords.
$ asadmin stop-instance --host myhost --port 1234 --user admin myinstance
The administrative server host is myhost, the administrative port is 1234, the administrative
username is admin. The server instance myinstance can be clustered or standalone.
For the full syntax, type asadmin help stop-instance.
Restarting an Instance
To restart server instance, stop and start the instance.

Recreating the Domain Administration Server
For mirroring purposes, and to provide a working copy of the Domain Administration Server
(DAS), you must have:
■
One machine (machine1) that contains the original DAS.
■
A second machine (machine2) that contains a cluster with server instances running
applications and catering to clients. The cluster is configured using the DAS on the first
machine.
■
A third backup machine (machine3) where the DAS needs to be recreated in case the first
machine crashes.
Note – You must maintain a backup of the DAS from the first machine. Use asadmin
backup-domain to backup the current domain.
▼
To migrate the DAS
The following steps are required to migrate the Domain Administration Server from the first
machine (machine1) to the third machine (machine3).
1
Install the application server on the third machine just as it is installed on the first machine.
This is required so that the DAS can be properly restored on the third machine and there are no
path conflicts.
a. Install the application server administration package using the command-line (interactive)
mode.To activate the interactive command-line mode, invoke the installation program
using the console option:
./bundle-filename -console
You must have root permission to install using the command-line interface.
b. Deselect the option to install default domain.
Restoration of backed up domains is only supported on two machines with same
architecture and exactly the same installation paths (use same as-install and
domain-root-dir on both machines).
2
3
Copy the backup ZIP file from the first machine into the domain-root-dir on the third machine.
You can also FTP the file.
Execute asadmin restore-domain command to restore the ZIP file onto the third machine:
asadmin restore-domain --filename domain-root-dir/sjsas_backup_v00001.zip domain1
You can backup any domain. However, while recreating the domain, the domain name should
be same as the original.
36
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Basic Enterprise Server Commands
4
Change domain-root-dir/domain1/generated/tmp directory permissions on the third machine
to match the permissions of the same directory on first machine.
The default permissions of this directory are: ?drwx------? (or 700).
For example:
chmod 700 domain-root-dir/domain1/generated/tmp
The example above assumes you are backing up domain1. If you are backing up a domain by
another name, you should replace domain1 above with the name of the domain being backed
up.
5
6
Change the host values for the properties in the domain.xml file for the third machine:
Update the domain-root-dir/domain1/config/domain.xml on the third machine.
For example, search for machine1 and replace it with machine3. So, you can change:
<jmx-connector><property name=client-hostname value=machine1/>...
to:
<jmx-connector><property name=client-hostname value=machine3/>...
7
Change:
<jms-service... host=machine1.../>
to:
<jms-service... host=machine3.../>
8
9
Start the restored domain on machine3:
asadmin start-domain --user admin-user --password admin-password domain1
Change the DAS host values for properties under node agent on machine2.
10 Change agent.das.host property value in
as-install/nodeagents/nodeagent/agent/config/das.properties on machine2.
11 Restart the node agent on machine2.
Note – Start the cluster instances using the asadmin start-instance command to allow them
to synchronize with the restored domain.

Java Business Integration
Java Business Integration (JBI) is an implementation of the JSR 208 specification
developed under the Java Community Process (JCP) as an approach to implementing a
service-oriented architecture (SOA).
JBI defines an environment for plug-in components that interact using a services model based
directly on Web Services Description Language (WSDL) 2.0. The plug-in components function
as service providers, service consumers, or both.
For detailed information on managing the key components of the JBI runtime environment and
their lifecycle states, see the Admin Console Online Help. For information about using the JBI
JBI Environment
The key components of the JBI environment are covered in the following sections.
■
■
■
■
JBI Components
Service Engines
Service Engines are components that provide local services (that is, services within the JBI
environment) and consume local or remote services.
39
JBI Environment
Binding Components
Binding Components are proxies for consumers or providers that are outside the JBI
environment. Binding components typically are based on a standard communications protocol,
such as FTP, JMS, or SMTP, or a call to an external service, such as SAP or WebSphere MQ.
JBI components have the following lifecyle states:
■
Started
■
Stopped
■
Shutdown
The JBI Runtime persists the life cycle states of JBI Components. When the server shuts down
and then restarts, JBI Components revert to their state at the time the Enterprise Server shut
down.
Note – The JBI runtime attempts to revert to the "desired" state of a JBI component. For
example, suppose you tried to start a JBI component but it did not start due to an error in the
component. If you restart the Enterprise Server, the JBI runtime attempts to start the
component again.
You can do the following operations on the JBI components. For detailed steps, log on to the
Admin Console, navigate to the JBI node, click Components and then click Online Help.
■
View JBI components by their specific lifestyle states.
■
Install JBI components.
■
Uninstall JBI components.

■
View the general properties of a JBI Component.
■
View the configuration information for a JBI Component.
■
View the descriptor for a JBI Component.
■
Manage JBI Component Loggers.
JBI Component Loggers
Using the Admin Console, you can manage the log levels for JBI Components. Some JBI
Components provide several loggers while other components might not provide any. However,
there will always be a logger level displayed for the entire component. But the logger level
setting will only have an effect if a component implements its loggers based on the default name.
The provider of a JBI Component might provide additional documentation on specifying
logging levels.
40
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
JBI Environment
Note – The logging levels for JBI Components are often inherited from a parent logger such as
the JBI logger. To view and set parent logging levels, in the Admin Console, select Common
Tasks and then Application Server. Then, in the Enterprise Server panel, select Logging and
then Log Levels. Look for the drop-down list for the JBI module to view and set the parent JBI
logging level.
Service Assemblies
A Service Assembly is a collection of Service Units that provision target components that
together provide or consume specific services for an application. Service Assemblies are
typically created in a development tools environment, such as that provided by NetBeans
Enterprise Pack.
A Service Assembly has the following lifecyle states:
■
Started
■
Shutdown
■
Stopped
The JBI Runtime persists the lifecycle states of Service Assemblies. When the Enterprise Server
shuts down and then restarts, Service Assemblies revert to their state at the time the Enterprise
Server shut down.
Note – The JBI runtime attempts to revert to the "desired" state of a Service Assembly. For
example, suppose you tried to start a Service Assembly but it did not start due to an error in the
Service Assembly. If you restart the Application Server, the JBI runtime attempts to start the
Service Assembly again.
You can do the following operations on Service Assemblies. For detailed steps, log on to the
Admin Console, navigate to the JBI node, click Service Assemblies and then click Online Help.
■
View all the Service Assemblies, with support for sorting and for filtering by lifecycle state.
■

Shared Libraries
A Shared Library provides Java classes that are not private to a single component and is typically
shared by more than one JBI Component. For example, the Java EE Service Engine requires the
WSDL Shared Library.
You can do the following operations on Shared Libraries. For detailed steps, log on to the
Admin Console, navigate to the JBI node, click Shared Libraries and then click Online Help.
■
View all Shared Libraries.
■
Install Shared Libraries.
■
View General Properties of a Shared Library.
■
View the descriptor for a Shared Library.
■

JBI Descriptors
The descriptor file (jbi.xml) for Service Assemblies, JBI Components, and Shared Libraries
provides the following information:
■
Service Assemblies: Lists the Service Units contained in the Service Assembly and the target
for each Service Unit. Some Service Units may also show information on connection
endpoints.
■
JBI Components: Lists the type of the JBI Component (Binding Component or Service
Engine), a description of the component, information about relevant classpaths for the
component, and the name of any Shared Library upon which it depends.
■
Shared Libraries: Lists the name of the shared library, and the names of the archive files
(.jar files) or class file subdirectories it contains.

JDBC Resources
This chapter explains how to configure JDBC resources, which are required by applications that
access databases. This chapter contains the following sections:
■
■
■
■
■
■
JDBC Resources
To store, organize, and retrieve data, most applications use relational databases. Java EE
applications access relational databases through the JDBC API.
A JDBC resource (data source) provides applications with a means of connecting to a database.
Typically, the administrator creates a JDBC resource for each database accessed by the
applications deployed in a domain. (However, more than one JDBC resource can be created for
a database.)
To create a JDBC resource, specify a unique JNDI name that identifies the resource. (See the
section JNDI Names and Resources.) Expect to find the JNDI name of a JDBC resource in
java:comp/env/jdbc subcontext. For example, the JNDI name for the resource of a payroll
database could be java:comp/env/jdbc/payrolldb. Because all resource JNDI names are in
the java:comp/env subcontext, when specifying the JNDI name of a JDBC resource in the
Admin Console, enter only jdbc/name. For example, for a payroll database specify
jdbc/payrolldb.
A JDBC resource (data source) provides applications with a means of connecting to a database.
Before creating a JDBC resource, first create a JDBC connection pool.
43
JDBC Connection Pools
When creating a JDBC resource, you must identify:
1. The JNDI Name. By convention, the name begins with the jdbc/ string. For example:
jdbc/payrolldb. Don’t forget the forward slash.
2. Select a connection pool to be associated with the new JDBC resource.
3. Specify the settings for the resource.
4. Identify the targets (clusters and standalone server instance) on which the resource is
available.
JDBC Connection Pools
To create a JDBC resource, specify the connection pool with which it is associated. Multiple
JDBC resources can specify a single connection pool.
A JDBC connection pool is a group of reusable connections for a particular database. Because
creating each new physical connection is time consuming, the server maintains a pool of
available connections to increase performance. When an application requests a connection, it
obtains one from the pool. When an application closes a connection, the connection is returned
to the pool.
The properties of connection pools can vary with different database vendors. Some common
properties are the database’s name (URL), user name, and password.

■
■
■
How JDBC Resources and Connection PoolsWorkTogether
To store, organize, and retrieve data, most applications use relational databases. Java EE
applications access relational databases through the JDBC API. Before an application can access
a database, it must get a connection.
At runtime, here’s what happens when an application connects to a database:
1. The application gets the JDBC resource (data source) associated with the database by
making a call through the JNDI API.
Given the resource’s JNDI name, the naming and directory service locates the JDBC
resource. Each JDBC resource specifies a connection pool.
2. Via the JDBC resource, the application gets a database connection.
44
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Setting Up Database Access
Behind the scenes, the application server retrieves a physical connection from the
connection pool that corresponds to the database. The pool defines connection attributes
such as the database name (URL), user name, and password.
3. Now that it is connected to the database, the application can read, modify, and add data to
the database.
The applications access the database by making calls to the JDBC API. The JDBC driver
translates the application’s JDBC calls into the protocol of the database server.
4. When it is finished accessing the database, the application closes the connection.
The application server returns the connection to the connection pool. Once it’s back in the
pool, the connection is available for the next application.
Setting Up Database Access
To setup a database access:
1. Install a supported database product.
For a list of database products supported by the Enterprise Server, see the Release Notes.
2. Install a JDBC driver for the database product.
3. Make the driver’s JAR file accessible to the domain’s server instance.
4. Create the database.
Usually, the application provider delivers scripts for creating and populating the database.
5. Create a connection pool for the database.
6. Create a JDBC resource that points to the connection pool.
Now to integrate the JDBC driver into an administrative domain, do either of the following:
1. Make the driver accessible to the common class loader.
Copy the driver’s JAR and ZIP files into the domain-dir/lib directory or copy its class files
into the domain-dir/lib/ext directory.
2. Restart the domain.
3. Identify the fully-qualified path name for the driver's JAR file.

45
Working with JDBC Connection Pools
Working with JDBC Connection Pools
A JDBC connection pool is a group of reusable connections for a particular database. When
creating the pool with the Admin Console, the Administrator is actually defining the aspects of
a connection to a specific database.
Before creating the pool, you must first install and integrate the JDBC driver. When building
the Create Connection Pool pages, certain data specific to the JDBC driver and the database
vendor must be entered. Before proceeding, gather the following information:
■
Database vendor name
■
Resource type, such as javax.sql.DataSource (local transactions only)
javax.sql.XADataSource (global transactions)
■
Data source class name
■
Required properties, such as the database name (URL), user name, and password
Creating a JDBC Connection Pool
You can use the Admin Console for creating the JDBC connection pool.
▼
Creating a JDBC Connection Pool and JDBC Resource Using the Admin
Console
1
Copy the JDBC driver for database connectivity to as-install/domains/domain_name/lib/ext.
Alternatively, add the path to the JDBC driver to classpath-prefix and restart the server.
2
3
In the Admin Console, click Create JDBC Connection Pool in the CommonTasks page.
Provide a name for the connection pool, select the resource type, select the database vendor.
Click Next.
4
The Admin Console lists the default pool settings and the properties of datasource class
provided by the vendor.

Creating a JDBC Connection Pool and JDBC Resource Using the CLI
1
Use the asadmin create-jdbc-connection-pool command to create a JDBC connection pool.
Sample command to create a JDBC connection pool:
asadmin create-jdbc-connection-pool --datasourceclassname
oracle.jdbc.pool.OracleDataSource --restype javax.sql.DataSource --property
user=dbuser:password=dbpassword:url="jdbc:oracle\:thin\:@localhost\:1521\:ORCL"
myjdbc_oracle-pool
2
Use the asadmin create-jdbc-resource command to create a JDBC resource assicated with
this connection pool.
Sample command to create a JDBC resource:
asadmin create-jdbc-connection-pool --connectionpoolid myjdbc_oracle-pool
jdbc/oracle-resource

4
Test the connection settings are correct by pinging the connection pool using the asadmin
ping-connection-pool command.
asadmin ping-connection-pool myjdbc_oracle-pool
To edit JDBC connection pool properties, use the asadmin list, get, and set commands.
Sample list command to list a JDBC connection pool:
asadmin list myjdbc_oracle-pool
The sample output of this command:
domain.resources.jdbc-connection-pool.oracle-pool
Sample get command to list all properties of a JDBC connection pool:

47
Working with JDBC Connection Pools
Editing a JDBC Connection Pool
The Edit JDBC Connection Pool page provides the means to change all of the settings for an
existing pool except its name.
1. Change general settings.
The values of the general settings depend on the specific JDBC driver that is installed. These
settings are the names of classes or interfaces in the Java programming language.
Parameter
Description
DataSource Class Name
The vendor-specific class name that implements the DataSource and / or
XADataSource APIs. This class is in the JDBC driver.
Resource Type
Choices include javax.sql.DataSource (local transactions only),
javax.sql.XADataSource (global transactions), and
java.sql.ConnectionPoolDataSource (local transactions, possible
performance improvements).
2. Change pool settings.
A set of physical database connections reside in the pool. When an application requests a
connection, the connection is removed from the pool, and when the application releases the
connection, it is returned to the pool.
Parameter
Description
Initial and Minimum Pool Size
The minimum number of connections in the pool. This value also
determines the number of connections placed in the pool when the pool is
first created.
Maximum Pool Size
Pool Resize Quantity
The maximum number of connections in the pool.
When the pool scales up and scales down towards the maximum and
minimum pool sizes respectively, it is resized in batches. This value
determines the number of connections in the batch. Making this value too
large delays connection creation and recycling; making it too small will be
less efficient.
Idle Timeout
The maximum time in seconds that a connection can remain idle in the
pool. After this time expires, the connection is removed from the pool.
Max Wait Time
The amount of time the application requesting a connection will wait before
getting a connection timeout. Because the default wait time is long, the
application might appear to hang indefinitely.
3. Change connection validation settings.
48
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Working with JDBC Connection Pools
Optionally, the application server can validate connections before they are passed to
applications. This validation allows the application server to automatically reestablish
database connections if the database becomes unavailable due to network failure or database
server crash. Validation of connections incurs additional overhead and slightly reduces
performance.
Parameter
Description
Connection Validation
Validation Method
Select the Required checkbox to enable connection validation.
The application server can validate database connections in three ways:
auto-commit, metadata, and table.
auto-commit and metadata - The application server validates a connection
by calling the con.getAutoCommit() and con.getMetaData() methods.
Auto-commit validation makes use of two methods for validating the
connection.getAutoCommit() is used to retrieve the current state of
auto-commit and setAutoCommit() to change the state of auto-commit.
This allows actual contact with the database to take place.
getAutomCommit()might or might not contact the database, depending on
the implementation. Actual physical connection will be wrapped for
different purposes, such as a connection pool.
Note – Because many JDBC drivers cache the results of these calls, they do
not always provide reliable validations. Check with the driver vendor to
determine whether these calls are cached or not.
table - The application queries a database table that are specified. The table
must exist and be accessible, but it doesn't require any rows. Do not use an
existing table that has a large number of rows or a table that is already
frequently accessed.
Table Name
If you selected table from the Validation Method combo box, then specify
the name of the database table here.
On Any Failure
If you select the checkbox labelled Close All Connections, if a single
connection fails, then the application server closes all connections in the
pool and then reestablish them. If you do not select the checkbox, then
individual connections are reestablished only when they are used.
Allow Non Component Callers Click this check box if you want to enable the pool for use by
non-component callers such as Servlet Filters and Lifecycle modules.
4. Change transaction isolation settings.
Because a database is usually accessed by many users concurrently, one transaction might
update data while another attempts to read the same data. The isolation level of a
transaction defines the degree to which the data being updated is visible to other
transactions. For details on isolation levels, refer to the documentation of the database
vendor.

Working with JDBC Connection Pools
Parameter
Description
Non-transactional Connections Click the check box if you want Application Server to return all
non-transactional connections.
Transaction Isolation
Makes it possible to select the transaction isolation level for the connections
of this pool. If left unspecified, the connections operate with default
isolation levels provided by the JDBC driver.
Guaranteed Isolation Level
Only applicable if the isolation level has been specified. If you select the
Guaranteed checkbox, then all connections taken from the pool have the
same isolation level. For example, if the isolation level for the connection is
changed programmatically (with con.setTransactionIsolation) when
last used, this mechanism changes the status back to the specified isolation
level.
5. Change properties.
In the Additional Properties table, it is possible to specify properties, such as the database
name (URL), user name, and password. Because the properties vary with database vendor,
consult the vendor’s documentation for details.
Editing JDBC Connection Pool Advanced Attributes
To help diagnose connection leaks and improve ease-of–use, Application Server 9.1 provides
several new attributes to configure a connection pool at the time of its creation.
1. Open the Advanced tab and specify the following attributes.
Attribute
Name
Description
Name of the JDBC connection pool whose
properties you want to edit. You cannot change the
pool name, however.
Statement Timeout
Wrap JDBC Objects
Time in seconds after which abnormally long
running queries will be terminated. Application
Server will set "QueryTimeout" on the statements
created. The default value of -1 implies that the
attribute is not enabled.
When set to true, application will get wrapped jdbc
objects for Statement, PreparedStatement,
CallableStatement, ResultSet, DatabaseMetaData.
The default value is false.
2. Specify the Connection Settings as explained in the following table.
50
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Working with JDBC Connection Pools
Attribute
Description
Validate Atmost Once
Amount of time, in seconds, after which a
connection is validated at most once. This will help
reduce the number of validation requests by a
connection. The default value 0 implies that
connection validation is not enabled.
Leak Timeout
Amount of time, in seconds, to trace connection
leaks in a connection pool. The default value 0
means that connection leak tracing is disabled. If
connection leak tracing is enabled, you can get
statistics on the number of connection leaks in the
Monitoring Resources tab. To view this tab, go to
Application Server > Monitoring > Resources.
Leak Reclaim
If this option is enabled, leaked connections will be
restored to the pool after leak connection tracing is
complete.
Creation Retry Attempts
Number of attempts that will be made if there is a
failure in creating a new connection. The default
value of 0 implies that no attempts will be made to
create the connection again.
Retry Interval
Specify the interval, in seconds, between two
attempts to create a connection. The default value is
10 seconds. This attribute is used only if the value of
Creation Retry Attempts is greater than 0.
Lazy Connection Enlistment
Lazy Association
Enable this option to enlist a resource to the
transaction only when it is actually used in a
method.
Connections are lazily associated when an operation
is performed on them. Also, they are disassociated
when the transaction is completed and a component
method ends, which helps reuse of the physical
connections. Default value is false.
Associate with Thread
Enable this option to associate a connection with the
thread such that when the same thread is in need of
a connection, it can reuse the connection already
associated with that thread, thereby not incurring
the overhead of getting a connection from the pool.
Default value is false.
Chapter 3 • JDBC Resources
51
Configurations for Specific JDBC Drivers
Match Connections
Use this option to switch on/off connection
matching for the pool. It can be set to false if the
administrator knows that the connections in the
pool will always be homogeneous and hence a
connection picked from the pool need not be
matched by the resource adapter. Default value is
false.
Max Connection Usage
Specify the number of times a connection should be
reused by the pool. Once a connection is reused for
the specified number of times, it will be closed. This
is useful, for instance, to avoid statement-leaks. The
default value of 0 implies that no connections will be
reused.
Configurations for Specific JDBC Drivers
Enterprise Server is designed to support connectivity to any database management system with
a corresponding JDBC driver. The following JDBC driver and database combinations are
supported. These combinations have been tested with Enterprise Server and are found to be
Java EE compatible.

Configuring Java Message Service Resources
The Enterprise Server implements the Java Message Service (JMS) API by integrating the
Message Queue software into the Enterprise Server. For basic JMS API administration tasks, use
the Enterprise Server Admin Console. For advanced tasks, including administering a Message
Queue cluster, use the tools provided in the MQ-as-install/imq/bin directory. For details about
administering Message Queue, see the Message Queue Administration Guide.
This chapter describes how to configure resources for applications that use the Java Message
Service (JMS) API. It contains the following sections:
JMS Resources
The Java Message Service (JMS) API uses two kinds of administered objects:
■
Connection factories, objects that allow an application to create other JMS objects
programmatically
■
Destinations, which serve as the repositories for messages
These objects are created administratively, and how they are created is specific to each
implementation of JMS. In the Enterprise Server, perform the following tasks:
■
Create a connection factory by creating a connection factory resource
■
Create a destination by creating two objects:
■
A physical destination
A destination resource that refers to the physical destination
■
JMS applications use the JNDI API to access the connection factory and destination resources.
A JMS application normally uses at least one connection factory and at least one destination. To
learn what resources to create, study the application or consult with the application developer.
There are three types of connection factories:
■
QueueConnectionFactory objects, used for point-to-point communication
63
The Relationship Between JMS Resources and Connector Resources
■
TopicConnectionFactory objects, used for publish-subscribe communication
■
ConnectionFactory objects, which can be used for both point-to-point and
publish-subscribe communications; these are recommended for new applications
There are two kinds of destinations:
■
Queue objects, used for point-to-point communication
Topic objects, used for publish-subscribe communication
■
The chapters on JMS in the Java EE 5 Tutorial provide details on these two types of
communication and other aspects of JMS (see
The order in which the resources are created does not matter.
For a Java EE application, specify connection factory and destination resources in the
Enterprise Server deployment descriptors as follows:
■
Specify a connection factory JNDI name in a resource-ref or an
mdb-connection-factory element.
■
Specify a destination resource JNDI name in the ejb element for a message-driven bean and
in the message-destination element.
■
Specify a physical destination name in a message-destination-link element, within either
a message-driven element of an enterprise bean deployment descriptor or a
message-destination-ref element. In addition, specify it in the message-destination
element. (The message-destination-ref element replaces the resource-env-ref
element, which is deprecated in new applications.) In the message-destination element of
an Enterprise Server deployment descriptor, link the physical destination name with the
destination resource name.
The Relationship Between JMS Resources and Connector
Resources
The Enterprise Server implements JMS by using a system resource adapter named jmsra. When
a user creates JMS resources, the Enterprise Server automatically creates connector resources
that appear under the Connectors node in the Admin Console’s tree view.
For each JMS connection factory that a user creates, the Enterprise Server creates a connector
connection pool and connector resource. For each JMS destination a user creates, the
Enterprise Server creates an admin object resource. When the user deletes the JMS resources,
the Enterprise Server automatically deletes the connector resources.
It is possible to create connector resources for the JMS system resource adapter by using the
Connectors node of the Admin Console instead of the JMS Resources node. See Chapter 7,
64
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
JMS Physical Destinations
JMS Connection Factories
JMS connection factories are objects that allow an application to create other JMS objects
programmatically. These administered objects implement the ConnectionFactory,
QueueConnectionFactory, and TopicConnectionFactory interfaces. Using the Enterprise
Server Admin Console, you can create, edit, or delete a JMS Connection Factory. The creation
of a new JMS connection factory also creates a connector connection pool for the factory and a
connector resource.
To manage JMS connection factories using the command-line utility, use
create-jms-resource, list-jms-resources, or delete-jms-resource command.
JMS Destination Resources
JMS destinations serve as the repositories for messages. Using the Admin Console, you can
create, modify or delete JMS Destination Resources. To create a new JMS Destination Resource,
select Resources >JMS Resources >Destination Resources. In the Destination Resources page,
you can specify the following:
■
JNDI Name for the resource. It is a recommended practice to use the naming subcontext
prefix jms/ for JMS resources. For example: jms/Queue.
■
The resource type, which can be javax.jms. Topic or javax.jms.Queue.
■
Additional properties for the destination resource. For more details about all these settings
and the additional properties, refer to the Admin Console Online Help.
To manage JMS destinations using the command-line utility, use create-jms-resource, or
delete-jms-resource command.
Tip – To specify the addresslist property (in the format
host:mqport,host2:mqport,host3:mqport) for asadmin create-jms-resource command,
escape the : by using \\. For example, host1\\:mqport,host2\\:mqport,host3\\:mpqport.
For more information on using escape characters, see the asadmin(8) man page.
JMS Physical Destinations
For production purposes, always create physical destinations. During the development and
testing phase, however, this step is not required. The first time that an application accesses a
destination resource, Message Queue automatically creates the physical destination specified by
the Name property of the destination resource. The physical destination is temporary and
expires after a period specified by a Message Queue configuration property.
Chapter 4 • Configuring Java Message Service Resources
65
Configuring JMS Provider Properties
To create a physical destination from the Admin Console, select Configuration >Physical
Destinations. In the Create Physical Destinations page, specify a name for the physical
destination and choose the type of destination, which can be topic or queue. For more details
about the fields and properties in the Physical Destinations page, refer the Admin Console
Online Help.
For production purposes, always create physical destinations. During the development and
testing phase, however, this step is not required. The first time an application accesses a
destination resource, Message Queue automatically creates the physical destination specified by
the Name property of the destination resource. The physical destination is temporary and
expires after a period specified by a Message Queue configuration property.
To manage JMS physical destinations using the command-line utility, use create-jmsdest,
flush-jmsdest, or delete-jmsdest command.
Configuring JMS Provider Properties
Use the JMS Service page in the Admin Console to configure properties to be used by all JMS
connections. In the Admin Console, select Configurations >Java Message Service. In the JMS
Service page, you can control the following general JMS settings.
■
Select Startup Timeout interval, which indicates the time that Enterprise Server waits for the
JMS service to start before aborting the startup.
■
Select JMS Service type, which decides whether you manage a JMS Service on a local or a
remote host.
■
Specify Start Arguments to customize the JMS service startup.
■
Select Reconnect checkbox to specify whether the JMS service attempts to reconnect to a
message server (or the list of addresses in the AddressList) when a connection is lost.
■
Specify Reconnect Interval in terms of number of seconds. This applies for attempts on each
address in the AddressList and for successive addresses in the list. If it is too short, this time
interval does not give a broker time to recover. If it is too long, the reconnect might
represent an unacceptable delay.
■
Specify the number of reconnect attempts. In the field, type the number of attempts to
connect (or reconnect) for each address in the AddressList before the client runtime tries
the next address in the list.
■
Choose the default JMS host.
■
In the Address List Behavior drop-down list, choose whether connection attempts are in the
order of addresses in the AddressList (priority) or in a random order (random).
■
In the Address List Iterations field, type the number of times the JMS service iterates
through the AddressList in an effort to establish (or reestablish) a connection.
66
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Foreign JMS Providers
■
In the MQ Scheme and MQ Service fields, type the Message Queue address scheme name
and the Message Queue connection service name if a non-default scheme or service is to be
used.
Values of all these properties can be updated at run time too. However, only those connection
factories that are created after the properties are updated, will get the updated values. The
existing connection factories will continue to have the original property values.
To manage JMS providers using the command-line utility, use the set or jms-ping commands.
Accessing Remote Servers
Changing the provider and host to a remote system causes all JMS applications to run on the
remote server. To use both the local server and one or more remote servers, create a connection
factory resource with the AddressList property to create connections that access remote servers.
Foreign JMS Providers
Generic Resource Adapter 1.5 for JMS is a Java EE Connector 1.5 resource adapter that can
wrap the JMS client library of external JMS providers such as IBM Websphere MQ, Tibco EMS,
and Sonic MQ among others, and thus integrate any JMS provider with a Java EE application
server. The adapter is a.rar archive that can be deployed and configured using a Enterprise
Server administration tools.
Configuring the Generic Resource Adapter for JMS
Enterprise Server's administration tools can be used to deploy and configure the generic
resource adapter for JMS. This section explains how to configure Generic Resource Adapter for
JMS with Enterprise Server.
Overall, the Resource Adapter can be configured to indicate whether the JMS provider supports
XA or not. It is also possible to indicate what mode of integration is possible with the JMS
provider. Two modes of integration are supported by the resource adapter. The first one uses
JNDI as the means of integration. In this case, administered objects are set up in the JMS
provider's JNDI tree and will be looked up for use by the generic resource adapter. If that mode
is not suitable for integration, it is also possible to use the Java reflection of JMS administered
object javabean classes as the mode of integration.
You can use the Admin Console or the command-line to configure the resource adapter. This is
not different from configuring any other resource adapter.

Configuring the Generic Resource Adapter
Prior to deploying the resource adapter, JMS client libraries should be made available to the
Enterprise Server. For some JMS providers, client libraries may also include native libraries. In
such cases, these native libraries should also be made available to the JVM(s).
1. Deploy the generic resource adapter the same way you would deploy a connector module.
2. Create a connector connection pool.
3. Create a connector resource.
4. Create an administered object resource.
5. Make the following changes to the security policy in the Enterprise Server:
■
Modify sjsas_home/domains/domain1/config/server.policy to add
java.util.logging.LoggingPermission "control"
■
Modify sjsas_home/lib/appclient/client.policy to add permission
javax.security.auth.PrivateCredentialPermission
"javax.resource.spi.security.PasswordCredential ^ \"^\"","read":

RMPolicy
ProviderManaged or

The isSameRM method on an
XAResource is used by the
OnePerPhysicalConnection Managed
Transaction Manager to determine if
the Resource Manager instance
represented by two XAResources are
the same. When RMPolicy is set to
ProviderManaged (the default value),
the JMS provider is responsible for
determining the RMPolicy and the
XAResource wrappers in the Generic
Resource Adapter merely delegate the
isSameRM call to the message queue
provider's XA resource
implementations. This should ideally
work for most message queue
products.
Some XAResource implementations
such as IBM MQ Series rely on a
resource manager per physical
connection and this causes issues
when there is inbound and outbound
communication to the same queue
manager in a single transaction (for
example, when an MDB sends a
response to a destination). When
RMPolicy is set to
OnePerPhysicalConnection, the
XAResource wrapper
implementation's isSameRM in
Generic Resource Adapter would
check if both the XAResources use the
same physical connection, before
delegating to the wrapped objects.

Configuring JavaMail Resources
The Enterprise Server includes the JavaMail API. The JavaMail API is a set of abstract APIs that
model a mail system. The API provides a platform-independent and protocol-independent
framework to build mail and messaging applications. The JavaMail API provides facilities for
reading and sending electronic messages. Service providers implement particular protocols.
Using the JavaMail API you can add email capabilities to your applications. JavaMail provides
access from Java applications to Internet Message Access Protocol (IMAP) and Simple Mail
Transfer Protocol (SMTP) capable mail servers on your network or the Internet. It does not
provide mail server functionality; you must have access to a mail server to use JavaMail.
The JavaMail API is implemented as a Java platform optional package and is also available as
part of the J2EE platform.
The Enterprise Server includes the JavaMail API along with JavaMail service providers that
allow an application component to send email notifications over the Internet and to read email
from IMAP and POP3 mail servers.
To learn more about the JavaMail API, consult the JavaMail web site at
This section contains the following topic:
Creating a JavaMail Session
To configure JavaMail for use in Enterprise Server, create a Mail Session in the Enterprise Server
Admin Console. This allows server-side components and applications to access JavaMail
services with JNDI, using the Session properties you assign for them. When creating a Mail
Session, you can designate the mail hosts, transport and store protocols, and the default mail
user in the Admin Console so that components that use JavaMail do not have to set these
properties. Applications that are heavy email users benefit because the Application Server
creates a single Session object and makes it available via JNDI to any component that needs it.
75
Creating a JavaMail Session
To create a JavaMail session using the Admin Console, select Resources —> JavaMail Sessions.
Specify the JavaMail settings as follows:
■
JNDI Name: The unique name for the mail session. Use the naming sub-context prefix mail/
for JavaMail resources. For example: mail/MySession.
■
Mail Host: The host name of the default mail server. The connect methods of the Store and
Transport objects use this value if a protocol-specific host property is not supplied. The
name must be resolvable to an actual host name.
■
Default User: The user name to provide when connecting to a mail server. The connect
methods of the Store and Transport objects use this value if a protocol-specific username
property is not supplied.
■
Default Return Address: The email address of the default user, in the form:
■
Description: Provide a descriptive statement for the component.
■
Session: Deselect the Enabled checkbox if you do not want to enable the mail session at this
time.
Additionally, define the following Advanced settings only if the mail provider has been
re-configured to use a non-default store or transport protocol:
■
Store Protocol: Defines the Store object communication method to be used. By default, the
Store Protocol is imap.
■
Store Protocol Class: Provides the Store communication method class that implements the
desired Store protocol. By default, the Store Protocol Class is
com.sun.mail.imap.IMAPStore.
■
Transport Protocol: Identifies the transport communication method. By default, the
Transport Protocol is smtp.
■
Transport Protocol Class: Defines the communication method for the transport class. By
default, the Transport Protocol Class is com.sun.mail.smtp.SMTPTransport.
■
Debug: Select this checkbox to enable extra debugging output, including a protocol trace,
for this mail session. If the JavaMail log level is set to FINE or finer, the debugging output is
generated and is included in the system log file.
■
Additional Properties: Create properties required by applications, such as a
protocol-specific host or username property. Ensure that every property name you define
start with a mail- prefix. If the name of the property does not start withmail-, the property
is ignored.

JNDI Resources
The Java Naming and Directory Interface (JNDI) is an application programming interface
(API) for accessing different kinds of naming and directory services. Java EE components locate
objects by invoking the JNDI lookup method.
JNDI is the acronym for the Java Naming and Directory Interface API. By making calls to this
API, applications locate resources and other program objects. A resource is a program object
that provides connections to systems, such as database servers and messaging systems. (A JDBC
resource is sometimes referred to as a data source.) Each resource object is identified by a
unique, people-friendly name, called the JNDI name. A resource object and its JNDI name are
bound together by the naming and directory service, which is included with the Enterprise
Server. To create a new resource, a new name-object binding is entered into the JNDI.
This section covers the following topics:
■
■
■
■
Java EE Naming Services
A JNDI name is a people-friendly name for an object. These names are bound to their objects by
the naming and directory service that is provided by a Java EE server. Because Java EE
components access this service through the JNDI API, the object usually uses its JNDI name.
When it starts up, the Enterprise Server reads information from the configuration file and
automatically adds JNDI database names to the name space.
Java EE application clients, enterprise beans, and web components are required to have access
to a JNDI naming environment.
The application component's naming environment is a mechanism that allows customization
of the application component's business logic during deployment or assembly. Use of the
77
Naming References and Binding Information
application component's environment allows the application component to be customized
without the need to access or change the application component's source code.
A Java EE container implements the application component's environment, and provides it to
the application component instance as a JNDI naming context. The application component's
environment is used as follows:
■
The application component's business methods access the environment using the JNDI
interfaces. The application component provider declares in the deployment descriptor all
the environment entries that the application component expects to be provided in its
environment at runtime.
■
The container provides an implementation of the JNDI naming context that stores the
application component environment. The container also provides the tools that allow the
deployer to create and manage the environment of each application component.
■
A deployer uses the tools provided by the container to initialize the environment entries that
are declared in the application component's deployment descriptor. The deployer sets and
modifies the values of the environment entries.
■
The container makes the environment naming context available to the application
component instances at runtime. The application component's instances use the JNDI
interfaces to obtain the values of the environment entries.
Each application component defines its own set of environment entries. All instances of an
application component within the same container share the same environment entries.
Application component instances are not allowed to modify the environment at runtime.
Naming References and Binding Information
A resource reference is an element in a deployment descriptor that identifies the component’s
coded name for the resource. More specifically, the coded name references a connection factory
for the resource. In the example given in the following section, the resource reference name is
jdbc/SavingsAccountDB.
The JNDI name of a resource and the name of the resource reference are not the same. This
approach to naming requires that you map the two names before deployment, but it also
decouples components from resources. Because of this de-coupling, if at a later time the
component needs to access a different resource, the name does not need to change. This
flexibility also makes it easier for you to assemble J2EE applications from preexisting
components.
The following table lists JNDI lookups and their associated references for the J2EE resources
used by the Enterprise Server.

Using Custom Resources
A custom resource accesses a local JNDI repository and an external resource accesses an
external JNDI repository. Both types of resources need user-specified factory class elements,
JNDI name attributes, etc. In this section, we will discuss how to configure JNDI connection
factory resources, for J2EE resources, and how to access these resources.
Within the Enterprise Server, you can create, delete, and list resources, as well as
list-jndi-entities.
Using External JNDI Repositories and Resources
Often applications running on the Enterprise Server require access to resources stored in an
external JNDI repository. For example, generic Java objects could be stored in an LDAP server
as per the Java schema. External JNDI resource elements let users configure such external
resource repositories. The external JNDI factory must implement
javax.naming.spi.InitialContextFactory interface.
An example of the use of an external JNDI resource is:
<resources>
<!-- external-jndi-resource element specifies how to access J2EE resources
-- stored in an external JNDI repository. The following example
-- illustrates how to access a java object stored in LDAP.
-- factory-class element specifies the JNDI InitialContext factory that
-- needs to be used to access the resource factory. property element

This chapter explains how to configure connectors, which are used to access enterprise
information systems (EISs). This chapter contains the following sections:
■
■
■
■
An Overview of Connectors
Also called a resource adapter, a connector module is a Java EE component that enables
applications to interact with enterprise information systems (EISs). EIS software includes
various types of systems: enterprise resource planning (ERP), mainframe transaction
processing, and non-relational databases, among others. Like other Java EE modules, to install a
connector module you deploy it.
A connector connection pool is a group of reusable connections for a particular EIS. To create a
connector connection pool, specify the connector module (resource adapter) that is associated
with the pool.
A connector resource is a program object that provides an application with a connection to an
EIS. To create a connector resource, specify its JNDI name and its associated connection pool.
Multiple connector resources can specify a single connection pool. The application locates the
resource by looking up its JNDI name. (For more information on JNDI, see the section JNDI
Names and Resources.) The JNDI name of a connector resource for an EIS is usually in the
java:comp/env/eis-specific subcontext.
The Enterprise Server implements JMS by using a connector module (resource adapter). See the
section, The Relationship Between JMS Resources and Connector Resources.

To Create a Connector Connection Pool
BeforeYou Begin Before creating the pool, deploy the connector module (resource adapter) associated with the
pool. The values that are specified for the new pool depend on the connector module that is
deployed.
1
In the tree component, expand the Resource node and then the Connectors node. Select the
Connector Connection Pools node. On the Connector Connection Pools page, click New.
2
On the first Create Connector Connection Pool page, specify the following settings:
a. In the Name field, enter a logical name for the pool.
Specify this name when creating a connector resource.
b. Select an entry from the Resource Adapter combo box.
The combo box displays a list of deployed resource adapters (connector modules).
3
Select a value from the Connection Definition combo box.
The choices in the combo box depend on the resource adapter you selected. The Connection
Definition attribute identifies a resource adapter's connection-definition element in
thera.xml file.
4
5
Click Next.
On the next Create Connector Connection Pool page, perform these tasks:
a. In the General Settings section verify that the values are correct.
b. For the fields in the Pool Settings section, the default values can be retained.
These settings can be changed at a later time. See “To Edit a Connector Connection Pool” on

In the tree component, expand the Resources node and then the Connectors node. Expand the
Connector Connection Pools node and select the connector connection pool you want to edit.
On the Edit Connector Connection Pool page, you can change the settings of this connection
pool. (Optional) Under General Settings, modify the description for the connection pool.
Under Pool Settings, you can specify the parameter values as explained in the following table.
Parameter
Description
Initial and Minimum Pool Size
The minimum number of connections in the pool.
This value also determines the number of connections
placed in the pool when the pool is first created or
when application server starts.
Maximum Pool Size
Pool Resize Quantity
The maximum number of connections in the pool.
When the pool scales up and scales down towards the
maximum and minimum pool size respectively, it is
resized in batches. This value determines the number
of connections in the batch. Making this value too
large will delay connection creation and recycling;
making it too small will make it less efficient.
Idle Timeout
The maximum time in seconds that a connection can
remain idle in the pool. After this time expires, the
connection is removed from the pool.
Max Wait Time
The amount of time the application requesting a
connection will wait before getting a connection
timeout.
Chapter 7 • Connector Resources
83
Managing Connector Connection Pools
On Any Failure
If you select the checkbox labelled Close All
Connections, if a single connection fails, then the
application server will close all connections in the
pool and then reestablish them. If you do not select
the checkbox, then individual connections will be
reestablished only when they are used.
Transaction Support
Use the Transaction Support list to select the type of
transaction support for the connection pool. The
chosen transaction support overrides the transaction
support attribute in the resource adapter associated
with this connection pool in a downward compatible
way. In other words, it can support a lower transaction
level than that specified in the resource adapter or the
same transaction level as that specified in resource
adapter, but it cannot specify a higher level. The
transaction support options include the following.
The None selection from the Transaction Support
menu indicates that the resource adapter does not
support resource manager local or JTA transactions
and does not implement XAResource or
LocalTransaction interfaces. For JAXR resource
adapters, you need to choose None from the
Transaction Support menu. JAXR resource adapters
do not support local or JTA transactions. Local
transaction support means that the resource adapter
supports local transactions by implementing the
LocalTransaction interface. Local transactions are
managed internal to a resource manager and involve
no external transaction managers. XA transaction
support means that the resource adapter supports
resource manager local and JTA transactions by
implementing the LocalTransaction and
XAResourceinterfaces. XA transactions are controlled
and coordinated by a transaction manager external to
a resource manager. Local transactions are managed
internal to a resource manager and involve no
external transaction managers.
Connection Validation
Select the Required checkbox to enable connection
validation.

Managing Connector Connection Pools
Lazy Association
Connections are lazily associated when an operation is performed on them. Also,
they are disassociated when the transaction is completed and a component
method ends, which helps reuse of the physical connections. Default value is false.
Lazy Connection
Enlistment
Enable this option to enlist a resource to the transaction only when it is actually
used in a method.
Associate with Thread
Enable this option to associate a connection with the thread such that when the
same thread is in need of a connection, it can reuse the connection already
associated with it, thereby not incurring the overhead of getting a connection from
the pool. Default value is false.
Match Connections
Use this option to switch on/off connection matching for the pool. It can be set to
false if the administrator knows that the connections in the pool will always be
homogeneous and hence a connection picked from the pool need not be matched
by the resource adapter. Default value is false.
Max Connection Usage
Specify the number of times a connection should be reused by the pool. Once a
connection is reused for the specified number of times, it will be closed. This is
useful, for instance, to avoid statement-leaks. The default value of 0 implies that
this attribute is not enabled.

TheWeb Container
The Web Container is a J2EE container that hosts web applications. The web container extends
the web server functionality by providing developers the environment to run servlets and
JavaServer Pages (JSP files).
The EJB Container
Enterprise beans (EJB components) are Java programming language server components that
contain business logic. The EJB container provides local and remote access to enterprise beans.
There are three types of enterprise beans: session beans, entity beans, and message-driven
beans. Session beans represent transient objects and processes and typically are used by a single
client. Entity beans represent persistent data, typically maintained in a database.
Message-driven beans are used to pass messages asynchronously to application modules and
services.
The container is responsible for creating the enterprise bean, binding the enterprise bean to the
naming service so other application components can access the enterprise bean, ensuring only
authorized clients have access to the enterprise bean’s methods, saving the bean’s state to
persistent storage, caching the state of the bean, and activating or passivating the bean when
necessary.

Configuring Security
Security is about protecting data: how to prevent unauthorized access or damage to it in storage
or transit. The Enterprise Server; has a dynamic, extensible security architecture based on the
Java EE standard. Built in security features include cryptography, authentication and
authorization, and public key infrastructure. The Enterprise Server is built on the Java security
model, which uses a sandbox where applications can run safely, without potential risk to
systems or users. The following topics are discussed:
■
■
■
■
■
■
■
■
■
■
■
Understanding Application and System Security
Broadly, there are two kinds of application security:
■
In programmatic security, application code written by the developer handles security chores.
As an administrator, you don't have any control over this mechanism. Generally,
programmatic security is discouraged since it hard-codes security configurations in the
application instead of managing it through the Java EE containers.
97
Tools for Managing Security
■
In declarative security, the container (the Enterprise Server) handles security through an
application's deployment descriptors. You can control declarative security by editing
deployment descriptors directly or with a tool such as deploytool. Because deployment
descriptors can change after an application is developed, declarative security allows for
more flexibility.
In addition to application security, there is also system security, which affects all the applications
on an Enterprise Server system.
Programmatic security is controlled by the application developer, so this document does not
discuss it; declarative security is somewhat less so, and this document touches on it
occasionally. This document is intended primarily for system administrators, and so focuses on
system security.
Tools for Managing Security
The Enterprise Server provides the following tools for managing security:
■
Admin Console, a browser-based tool used to configure security for the entire server, to
manage users, groups, and realms, and to perform other system-wide security tasks. For a
an overview of the security tasks consult the Admin Console online help.
■
asadmin, a command-line tool that performs many of the same tasks as the Admin Console.
You may be able to do some things with asadmin that you cannot do with Admin Console.
You perform asadmin commands from either a command prompt or from a script, to
The Java Platform, Standard Edition (Java SE) provides two tools for managing security:
■
keytool, a command-line utility for managing digital certificates and key pairs. Use
keytool to manage users in the certificate realm.
■
policytool, a graphical utility for managing system-wide Java security policies. As an
administrator, you will rarely need to use policytool.
For more information on using keytool, policytool, and other Java security tools, see JDK
In the Enterprise Profile, two other tools that implement Network Security Services (NSS) are
available for managing security. For more information on NSS, go to
http://www.mozilla.org/projects/security/pki/nss/. The tools for managing security
include the following:
■
certutil, a command-line utility for managing certificates and key databases.
■
pk12util, a command-line utility used to import and export keys and certificates between
the certificate/key databases and files in PKCS12 format.

Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Managing Security of Passwords
For more information on using certutil, pk12util, and other NSS security tools, see NSS
Managing Security of Passwords
In the Enterprise Server, the file domain.xml, which contains the specifications for a particular
domain, initially contains the password of the Message Queue broker in clear text. The element
in the domain.xml file that contains this password is the admin-password attribute of the
jms-host element. Because this password is not changeable at installation time, it is not a
significant security impact.
However, use the Admin Console to add users and resources and assign passwords to these
users and resources. Some of these passwords are written to the domain.xml file in clear text, for
example, passwords for accessing a database. Having these passwords in clear text in the
domain.xml file can present a security hazard. You can encrypt any password in domain.xml,
including the admin-password attribute or a database password. Instructions for managing the
security passwords is included in the following topics:
■
■
■
■
■
Encrypting a Password in thedomain.xml File
To encrypt a password in the domain.xml file. Follow these steps:
1. From the directory where the domain.xml file resides (domain-dir/config by default), run
the following asadmin command:
asadmin create-password-alias --user admin alias-name
For example,
asadmin create-password-alias --user admin jms-password
A password prompt appears (admin in this case). Refer to the man pages for the
create-password-alias, list-password-aliases, delete-password-alias commands
for more information.
2. Remove and replace the password in domain.xml. This is accomplished using the asadmin
set command. An example of using the set command for this purpose is as follows:
asadmin set --user admin server.jms-service.jms-host.
default_JMS_host.admin-password=’${ALIAS=jms-password}’
Chapter 9 • Configuring Security
99
Managing Security of Passwords
Note – Enclose the alias password in single quotes as shown in the example.
3. Restart the Enterprise Server for the relevant domain.
Protecting Files with Encoded Passwords
Some files contain encoded passwords that need protecting using file system permissions. These
files include the following:
■
domain-dir/master-password
This file contains the encoded master password and should be protected with file system
permissions 600.
■
Any password file created to pass as an argument using the --passwordfile argument to
asadmin should be protected with file system permissions 600.
Changing the Master Password
The master password (MP) is an overall shared password. It is never used for authentication
and is never transmitted over the network. This password is the central point for overall
security; the user can choose to enter it manually when required, or obscure it in a file. It is the
most sensitive piece of data in the system. The user can force prompting for the master
password by removing this file. When the master password is changed, it is re-saved in the
master-password keystore, which is a Java JCEKS type keystore.
To change the master password, follow these steps:
1. Stop the Enterprise Server for the domain. Use the asadmin change-master-password
command, which prompts for the old and new passwords, then re-encrypts all dependent
items. For example:
asadmin change-master-password>
Please enter the master password>
Please enter the new master password>
Please enter the the new master password again>
2. Restart the Enterprise Server.
100
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Managing Security of Passwords
Caution – At this point in time, server instances that are running must not be started and
running server instances must not be restarted until the SMP on their corresponding node
agent has been changed. If a server instance is restarted before changing its SMP, it will fail to
come up.
3. Stop each node agent and its related servers one at a time. Run the asadmin
change-master-password command again, and then restart the node agent and its related
servers.
4. Continue with the next node agent until all node agents have been addressed. In this way, a
rolling change is accomplished.
Working with the Master Password and Keystores
The master password is the password for the secure keystore . When a new application server
domain is created, a new self-signed certificate is generated and stored in the relevant keystore,
which is locked using the master password. If the master password is not the default, the
start-domain command prompts you for the master password. Once the correct master
password is entered, the domain starts.
When a node agent associated with the domain is created, the node agent synchronizes the data
with domain. While doing so, the keystore is also synchronized. Any server instance controlled
by this node agent needs to open the keystore. Since the store is essentially identical to the store
that was created by the domain creation process, it can only be opened by an identical master
password. But the master password itself is never synchronized, meaning it is not transmitted to
the node agent during the synchronization, but needs to be available with the node agent
locally. This is why creation and/or starting of a node agent prompts you for the master
password and you need to enter the same password that you entered while creating/starting the
domain. If the master password is changed for a domain, you will have to perform the same step
to change it at every node agent that is associated with this domain.
Changing the Admin Password
Encrypting the admin password is strongly encouraged. If you want to change the admin
password before encrypting it, use the change-admin-password command.
Consult the Admin Console online help for instructions on changing the admin password using
the Admin Console.

About Authentication and Authorization
About Authentication and Authorization
Authentication and authorization are central concepts of application server security. The
following topics are discussed related to authentication and authorization:
■
■
■
■
■
Authenticating Entities
Authentication is the way an entity (a user, an application, or a component) determines that
another entity is who it claims to be. An entity uses security credentials to authenticate itself.
The credentials may be a user name and password, a digital certificate, or something else.
Typically, authentication means a user logging in to an application with a user name and
password; but it might also refer to an EJB providing security credentials when it requests a
resource from the server. Usually, servers or applications require clients to authenticate;
additionally, clients can require servers to authenticate themselves, too. When authentication is
bidirectional, it is called mutual authentication.
When an entity tries to access a protected resource, the Enterprise Server uses the
authentication mechanism configured for that resource to determine whether to grant access.
For example, a user can enter a user name and password in a Web browser, and if the
application verifies those credentials, the user is authenticated. The user is associated with this
authenticated security identity for the remainder of the session.
The Enterprise Server supports four types of authentication. An application specifies the type of
authentication it uses within its deployment descriptors.

About Authentication and Authorization
TABLE 9–1 Enterprise Server Authentication Methods
(Continued)
Server authenticates the client based SSL and TLS
on an encrypted response.
DIGEST
HTTP and SIP
Verifying Single Sign-On
Single sign-on enables multiple applications in one virtual server instance to share the user
authentication state. With single sign-on, a user who logs in to one application becomes
implicitly logged in to other applications that require the same authentication information.
Single sign-on is based on groups. All Web applications whose deployment descriptor defines
the same group and use the same authentication method (BASIC, FORM, CLIENT-CERT)
share single sign-on.
Single sign-on is enabled by default for virtual servers defined for the Enterprise Server.
Authorizing Users
Once a user is authenticated, the level of authorization determines what operations can be
performed. A user's authorization is based on his role. For example, a human resources
application may authorize managers to view personal employee information for all employees,
but allow employees to view only their own personal information. For more on roles, see
Specifying JACC Providers
JACC (Java Authorization Contract for Containers) is part of the Java EE specification that
defines an interface for pluggable authorization providers. This enables the administrator to set
up third-party plug-in modules to perform authorization.
By default, the Enterprise Server provides a simple, file-based authorization engine that
complies with the JACC specification. It is also possible to specify additional third-party JACC
providers.
JACC providers use the Java Authentication and Authorization Service (JAAS) APIs. JAAS
enables services to authenticate and enforce access controls upon users. It implements a Java
technology version of the standard Pluggable Authentication Module (PAM) framework.
Auditing Authentication and Authorization Decisions
The Enterprise Server can provide an audit trail of all authentication and authorization
decisions through audit modules. The Enterprise Server provides a default audit module, as well
as the ability to customize the audit modules.
Chapter 9 • Configuring Security
103
Understanding Users, Groups, Roles, and Realms
Configuring Message Security
Message Security enables a server to perform end-to-end authentication of web service
invocations and responses at the message layer. The Enterprise Server implements message
security using message security providers on the SOAP layer. The message security providers
provide information such as the type of authentication that is required for the request and
response messages. The types of authentication that are supported include the following:
■
Sender authentication, including username-password authentication.
Content authentication, including XML Digital Signatures.
■
Two message security providers are included with this release. The message security providers
can be configured for authentication for the SOAP layer. The providers that can be configured
include ClientProvider and ServerProvider.
Support for message layer security is integrated into the Enterprise Server and its client
containers in the form of (pluggable) authentication modules. By default, message layer security
is disabled on the Enterprise Server.
Message level security can be configured for the entire Enterprise Server or for specific
applications or methods. Configuring message security at the Enterprise Server level is
application level is discussed in the Developer's Guide.
Understanding Users, Groups, Roles, and Realms
The Enterprise Server enforces its authentication and authorization policies upon the following
entities:
■
is a person, a software component such as an enterprise bean, or even a service. A user who
has been authenticated is sometimes called a principal. Users are sometimes referred to as
subjects.
■
traits.
■
compared to a key that opens a lock. Many people might have a copy of the key. The lock
doesn't care who seeks access, only that the right key is used.
■
associated security credentials. A realm is also called a security policy domain.
104
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Understanding Users, Groups, Roles, and Realms
Note – Users and groups are designated for the entire Enterprise Server, whereas each
application defines its own roles. When the application is being packaged and deployed, the
application specifies mappings between users/groups and roles, as illustrated in the following
figure.
FIGURE 9–1 RoleMapping
Users
A user is an individual (or application program) identity that has been defined in the Enterprise
Server. A user can be associated with a group. The Enterprise Server authentication service can
govern users in multiple realms.
Groups
A Java EE group (or simply group) is a category of users classified by common traits, such as job
title or customer profile. For example, users of an e-commerce application might belong to the
customer group, but the big spenders would belong to the preferred group. Categorizing users
into groups makes it easier to control the access of large numbers of users.
Chapter 9 • Configuring Security
105
Understanding Users, Groups, Roles, and Realms
Roles
A role defines which applications and what parts of each application users can access and what
they can do. In other words, roles determine users' authorization levels.
For example, in a personnel application all employees might have access to phone numbers and
email addresses, but only managers would have access to salary information. The application
might define at least two roles: employee and manager; only users in the manager role are
allowed to view salary information.
A role is different from a user group in that a role defines a function in an application, while a
group is a set of users who are related in some way. For example, in the personnel application
there might be groups such as full-time, part-time, and on-leave, but users in all these
groups would still be in the employee role.
Roles are defined in application deployment descriptors. In contrast, groups are defined for an
entire server and realm. The application developer or deployer maps roles to one or more
groups for each application in its deployment descriptor.
Realms
A realm, also called a security policy domain or security domain, is a scope over which the server
defines and enforces a common security policy. In practical terms, a realm is a repository where
the server stores user and group information.
The Enterprise Server comes preconfigured with three realms: file (the initial default realm),
certificate, and admin-realm. It is possible to also set up ldap, JDBC, solaris, or custom
realms. Applications can specify the realm to use in their deployment descriptor. If they do not
specify a realm, the Enterprise Server uses its default realm.
In the file realm, the server stores user credentials locally in a file named keyfile. You can use
the Admin Console to manage users in the file realm.
In the certificate realm, the server stores user credentials in a certificate database. When
using the certificate realm, the server uses certificates with the HTTPS protocol to
authenticate Web clients. For more information about certificates, see “Introduction to
The admin-realm is also a FileRealm and stores administrator user credentials locally in a file
named admin-keyfile. Use the Admin Console to manage users in this realm in the same way
you manage users in the file realm.
In the ldap realm the server gets user credentials from a Lightweight Directory Access Protocol
(LDAP) server such as the Directory Server. LDAP is a protocol for enabling anyone to locate
organizations, individuals, and other resources such as files and devices in a network, whether
on the public Internet or on a corporate intranet. Consult your LDAP server documentation for
information on managing users and groups in the ldap realm.

Understanding Users, Groups, Roles, and Realms
In the JDBC realm, the server gets user credentials from a database. The Enterprise Server uses
the database information and the enabled JDBC realm option in the configuration file. For
digest authentication, a JDBC realm should be created with jdbcDigestRealm as the JAAS
context.
In the solaris realm the server gets user credentials from the Solaris operating system. This
realm is supported on the Solaris 9 OS and later. Consult your Solaris documentation for
information on managing users and groups in the solaris realm.
A custom realm is any other repository of user credentials, such as a relational database or
third-party component. For more information, see the Admin Console online help.
▼
To Configure aJDBC Realm for aWeb, EJB Application
The Enterprise Server enables you to specify a user's credentials in the JDBC realm instead of in
the connection pool. Using the JDBC realm instead of the connection pool prevents other
applications from browsing the database tables for the user's credentials. A user's credentials are
the user's name and password.
Note – By default, storage of passwords as clear text is not supported in the JDBC realm. Under
normal circumstances, passwords should not be stored as clear text.

Create the database tables in which to store the users' credentials for the realm.
How to create the database tables depends on the database that you are using.
How to add users' credentials to the database tables depends on the database that you are using.
Create a JDBC realm.
Use the Admin Console GUI for this purpose. For instructions for creating a JDBC realm, see the
online help for the Admin Console GUI.

To specify the realm, modify the appropriate deployment descriptor for your application:
■
For an enterprise application in an Enterprise Archive (EAR) file, modify the
sun-application.xml file.
■
For a web application in aWeb Application Archive (WAR) file, modify the web.xml file.
■
For an enterprise bean in an EJB JAR file, modify the sun-ejb-jar.xml file.

Assign a security role to users in the realm.
To assign a security role to a user, add a security-role-mapping element to the deployment
The following example shows a security-role-mapping element that assigns the security role
Employee to user Calvin.
<security-role-mapping>
<role-name>Employee</role-name>
<principal-name>Calvin</principal-name>

Introduction to Certificates and SSL
The following topics are discussed in this section:
■
■
About Digital Certificates
Digital certificates (or simply certificates) are electronic files that uniquely identify people and
resources on the Internet. Certificates also enable secure, confidential communication between
two entities.
There are different kinds of certificates, such as personal certificates, used by individuals, and
server certificates, used to establish secure sessions between the server and clients through
secure sockets layer (SSL) technology. For more information on SSL, see “About Secure Sockets
Certificates are based on public key cryptography, which uses pairs of digital keys (very long
numbers) to encrypt, or encode, information so it can be read only by its intended recipient. The
recipient then decrypts (decodes) the information to read it.
A key pair contains a public key and a private key. The owner distributes the public key and
makes it available to anyone. But the owner never distributes the private key; it is always kept
secret. Because the keys are mathematically related, data encrypted with one key can be
decrypted only with the other key in the pair.
A certificate is like a passport: it identifies the holder and provides other important information.
Certificates are issued by a trusted third party called a Certification Authority (CA). The CA is
analogous to passport office: it validates the certificate holder's identity and signs the certificate
so that it cannot be forged or tampered with. Once a CA has signed a certificate, the holder can
present it as proof of identity and to establish encrypted, confidential communications.
108
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Introduction to Certificates and SSL
Most importantly, a certificate binds the owner's public key to the owner's identity. Like a
passport binds a photograph to personal information about its holder, a certificate binds a
public key to information about its owner.
In addition to the public key, a certificate typically includes information such as:
■
The name of the holder and other identification, such as the URL of the Web server using
the certificate, or an individual's email address.
■
The name of the CA that issued the certificate.
■
An expiration date.
Digital Certificates are governed by the technical specifications of the X.509 format. To verify
the identity of a user in the certificate realm, the authentication service verifies an X.509
certificate, using the common name field of the X.509 certificate as the principal name.
About Certificate Chains
Web browsers are preconfigured with a set of root CA certificates that the browser
automatically trusts. Any certificates from elsewhere must come with a certificate chain to verify
their validity. A certificate chain is series of certificates issued by successive CA certificates,
eventually ending in a root CA certificate.
When a certificate is first generated, it is a self-signed certificate. A self-signed certificate is one
for which the issuer (signer) is the same as the subject (the entity whose public key is being
authenticated by the certificate). When the owner sends a certificate signing request (CSR) to a
CA, then imports the response, the self-signed certificate is replaced by a chain of certificates. At
the bottom of the chain is the certificate (reply) issued by the CA authenticating the subject's
public key. The next certificate in the chain is one that authenticates the CA's public key.
Usually, this is a self-signed certificate (that is, a certificate from the CA authenticating its own
public key) and the last certificate in the chain.
In other cases, the CA can return a chain of certificates. In this case, the bottom certificate in the
chain is the same (a certificate signed by the CA, authenticating the public key of the key entry),
but the second certificate in the chain is a certificate signed by a different CA, authenticating the
public key of the CA to which you sent the CSR. Then, the next certificate in the chain is a
certificate authenticating the second CA's key, and so on, until a self-signed root certificate is
reached. Each certificate in the chain (after the first) thus authenticates the public key of the
signer of the previous certificate in the chain.
About Secure Sockets Layer
Secure Sockets Layer (SSL) is the most popular standard for securing Internet communications
and transactions. Web applications use HTTPS (HTTP over SSL), which uses digital certificates
to ensure secure, confidential communications between server and clients. In an SSL
connection, both the client and the server encrypt data before sending it, then decrypt it upon
receipt.
Chapter 9 • Configuring Security
109
Introduction to Certificates and SSL
When a Web browser (client) wants to connect to a secure site, an SSL handshake happens:
■
The browser sends a message over the network requesting a secure session (typically, by
requesting a URL that begins with https instead of http).
■
■
The server responds by sending its certificate (including its public key).
The browser verifies that the server's certificate is valid and is signed by a CA whose
certificate is in the browser's database (and who is trusted). It also verifies that the CA
certificate has not expired.
■
If the certificate is valid, the browser generates a one time, unique session key and encrypts it
with the server's public key. The browser then sends the encrypted session key to the server
so that they both have a copy.
■
The server decrypts the message using its private key and recovers the session key.
After the handshake, the client has verified the identity of the Web site, and only the client and
the Web server have a copy of the session key. From this point forward, the client and the server
use the session key to encrypt all their communications with each other. Thus, their
communications are ensured to be secure.
The newest version of the SSL standard is called TLS (Transport Layer Security). The Enterprise
Server supports the Secure Sockets Layer (SSL) 3.0 and the Transport Layer Security (TLS) 1.0
encryption protocols.
To use SSL, the Enterprise Server must have a certificate for each external interface, or IP
address, that accepts secure connections. The HTTPS service of most Web servers will not run
unless a digital certificate has been installed. Use the procedure described in “Generating a
server can use for SSL.
About Ciphers
A cipher is a cryptographic algorithm used for encryption or decryption. SSL and TLS protocols
support a variety of ciphers used to authenticate the server and client to each other, transmit
certificates, and establish session keys.
Some ciphers are stronger and more secure than others. Clients and servers can support
different cipher suites. Choose ciphers from the SSL3 and TLS protocols. During a secure
connection, the client and the server agree to use the strongest cipher they both have enabled for
communication, so it is usually sufficient to enable all ciphers.
Using Name-basedVirtual Hosts
Using name-based virtual hosts for a secure application can be problematic. This is a design
limitation of the SSL protocol itself. The SSL handshake, where the client browser accepts the
server certificate, must occur before the HTTP request is accessed. As a result, the request
information containing the virtual host name cannot be determined prior to authentication,
and it is therefore not possible to assign multiple certificates to a single IP address.
110
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
About Certificate Files
If all virtual hosts on a single IP address need to authenticate against the same certificate, the
addition of multiple virtual hosts probably will not interfere with normal SSL operations on the
server. Be aware, however, that most browsers will compare the server's domain name against
the domain name listed in the certificate, if any (applicable primarily to official, CA-signed
certificates). If the domain names do not match, these browsers display a warning. In general,
only address-based virtual hosts are commonly used with SSL in a production environment.
About Firewalls
A firewall controls the flow of data between two or more networks, and manages the links
between the networks. A firewall can consist of both hardware and software elements. This
section describes some common firewall architectures and their configuration. The information
here pertains primarily to the Enterprise Server. For details about a specific firewall technology,
refer to the documentation from your firewall vendor.
In general, configure the firewalls so that clients can access the necessary TCP/IP ports. For
example, if the HTTP listener is operating on port 8080, configure the firewall to allow HTTP
requests on port 8080 only. Likewise, if HTTPS requests are setup for port 8181, you must
configure the firewalls to allow HTTPS requests on port 8181.
If direct Remote Method Invocations over Internet Inter-ORB Protocol (RMI-IIOP) access
from the Internet to EJB modules are required, open the RMI-IIOP listener port as well, but this
is strongly discouraged because it creates security risks.
In double firewall architecture, you must configure the outer firewall to allow for HTTP and
HTTPS transactions. You must configure the inner firewall to allow the HTTP server plug-in to
communicate with the Enterprise Server behind the firewall.
About Certificate Files
Installation of the Enterprise Server generates a digital certificate in JSSE (Java Secure Socket
Extension) or NSS (Network Security Services) format suitable for internal testing. By default,
the Enterprise Server stores its certificate information in a certificate database in the
domain-dir/config directory:
■
Keystore file, key3.db, contains the Enterprise Server's certificate, including its private key.
The keystore file is protected with a password. Change the password using the asadmin
change-master-password command.
Each keystore entry has a unique alias. After installation, the Enterprise Server keystore has
a single entry with alias s1as.
■
Truststore file, cert8.db, contains the Enterprise Server's trusted certificates, including
public keys for other entities. For a trusted certificate, the server has confirmed that the
public key in the certificate belongs to the certificate's owner. Trusted certificates generally
include those of certification authorities (CAs).
Chapter 9 • Configuring Security
111
Using Java Secure Socket Extension (JSSE)Tools
In the Developer Profile, on the server side, the Enterprise Server uses the JSSE format,
which uses keytool to manage certificates and key stores. In the Clusters and Enterprise
Profile, on the server side, the Enterprise Server uses NSS, which uses certutil to manage
the NSS database which stores private keys and certificates. In both profiles, the client side
(appclient or stand-alone), uses the JSSE format.
By default, the Enterprise Server is configured with a keystore and truststore that will work
with the example applications and for development purposes. For production purposes, you
may wish to change the certificate alias, add other certificates to the truststore, or change the
name and/or location of the keystore and truststore files.
Changing the Location of Certificate Files
The keystore and truststore files provided for development are stored in the domain-dir/config
directory.
Use the Admin Console to add or modify the value field for the new location of the certificate
files.
-Dcom.sun.appserv.nss.db=${com.sun.aas.instanceRoot}/NSS-database-directory
where NSS-database-directory is the location of the NSS database.
Using Java Secure Socket Extension (JSSE)Tools
Use keytool to set up and work with JSSE (Java Secure Socket Extension) digital certificates. In
the Developer Profile, the Enterprise Server uses the JSSE format on the server side to manage
certificates and key stores. In all the profiles, the client side (appclient or stand-alone) uses the
JSSE format.
The J2SE SDK ships with keytool, which enables the administrator to administer
public/private key pairs and associated certificates. It also enables users to cache the public keys
(in the form of certificates) of their communicating peers.
To run keytool, the shell environment must be configured so that the J2SE /bin directory is in
the path, or the full path to the tool must be present on the command line. For more
information on keytool, see the keytool documentation at

Generating a Certificate Using the keytool Utility
Use keytool to generate, import, and export certificates. By default, keytool creates a keystore
file in the directory where it is run.
1. Change to the directory where the certificate is to be run.
Always generate the certificate in the directory containing the keystore and truststore files,
by default domain-dir/config. For information on changing the location of these files, see
2. Enter the following keytool command to generate the certificate in the keystore file,
keystore.jks:
keytool -genkey -alias keyAlias-keyalg RSA
-keypass changeit
-storepass changeit
-keystore keystore.jks
Use any unique name as your keyAlias. If you have changed the keystore or private key
password from their default, then substitute the new password for changeit in the above
command. The default key password alias is “s1as.”
A prompt appears that asks for your name, organization, and other information that
keytool uses to generate the certificate.
3. Enter the following keytool command to export the generated certificate to the file
server.cer (or client.cer if you prefer):
keytool -export -alias keyAlias-storepass changeit
-file server.cer
-keystore keystore.jks
5. To create the truststore file cacerts.jks and add the certificate to the truststore, enter the
following keytool command:
keytool -import -v -trustcacerts
-alias keyAlias
-file server.cer
-keystore cacerts.jks
-keypass changeit

6. If you have changed the keystore or private key password from their default, then substitute
the new password for changeit in the above command.
The tool displays information about the certificate and prompts whether you want to trust
the certificate.
7. Type yes, then press Enter.
Then keytool displays something like this:

[Saving cacerts.jks]
8. Restart the Enterprise Server.
Signing a Digital Certificate Using the keytool Utility
After creating a digital certificate, the owner must sign it to prevent forgery. E-commerce sites,
or those for which authentication of identity is important can purchase a certificate from a
well-known Certificate Authority (CA). If authentication is not a concern, for example if private
secure communications is all that is required, save the time and expense involved in obtaining a
CA certificate and use a self-signed certificate.
1. Follow the instructions on the CA's Web site for generating certificate key pairs.
2. Download the generated certificate key pair.
Save the certificate in the directory containing the keystore and truststore files, by default
3. In your shell, change to the directory containing the certificate.
4. Use keytool to import the certificate into the local keystore and, if necessary, the local
truststore.
keytool -import -v -trustcacerts
-alias keyAlias
-file server.cer
-keystore cacerts.jks
-keypass changeit
-storepass changeit
If the keystore or private key password is not the default password, then substitute the new
password for changeit in the above command.
5. Restart the Enterprise Server.
Deleting a Certificate Using thekeytool Utility
To delete an existing certificate, use the keytool -delete command, for example:

Using Network Security Services (NSS)Tools
In the Clusters and Enterprise Profile, use Network Security Services (NSS) digital certificates
on the server-side to manage the database that stores private keys and certificates. For the client
side (appclient or stand-alone), use the JSSE format as discussed in “Using Java Secure Socket
The tools for managing security with Network Security Services (NSS) include the following:

The tools are located in the as-install/lib/ directory. The following environment variables are
used to point to the location of the NSS security tools:
■
LD_LIBRARY_PATH =${as-install}/lib
${os.nss.path}
■
In the examples, the certificate common name (CN) is the name of the client or server. The CN
is also used during SSL handshake for comparing the certificate name and the host name from
which it originates. If the certificate name and the host name do not match, warnings or
exceptions are generated during SSL handshake. In some examples, the certificate common
name CN=localhost is used for convenience so that all users can use that certificate instead of
creating a new one with their real host name.
The examples in the following sections demonstrate usage related to certificate handling using
NSS tools:

Using the certutil Utility
Before running certutil, make sure that LD_LIBRARY_PATH points to the location of the
libraries required for this utility to run. This location can be identified from the value of
AS_NSS_LIB in asenv.conf (product wide configuration file).
The certificate database tool, certutil, is an NSS command-line utility that can create and
modify the Netscape Communicator cert8.db and key3.db database files. It can also list,
generate, modify, or delete certificates within the cert8.db file and create or change the
password, generate new public and private key pairs, display the contents of the key database, or
delete key pairs within the key3.db file.
The key and certificate management process generally begins with creating keys in the key
database, then generating and managing certificates in the certificate database. The following
document discusses certificate and key database management with NSS, including the syntax
for the certutil utility:
Each of the items in the list below gives an example using NSS and JSSE security tools to create
and/or manage certificates.
■
Generate a self-signed server and client certificate. In this example, the CN must be of the
form hostname.domain.[com|org|net|...].
In this example, domain-dir/config. The serverseed.txt and clientseed.txt files can

J2SE 5.0 PKCS#11 providers can be easily integrated with the Enterprise Server runtime.
Through these providers, you can use hardware accelerators and other PKCS#11 tokens in
Enterprise Server to achieve fast performance and to protect the private key inherent in SSL or
TLS communications.

About Configuring Hardware Crypto Accelerators
Sun GlassFish Enterprise Server has been tested with Sun Crypto Accelerator 1000 (SCA-1000)
and SCA-4000.
Enterprise Server can communicate with PKCS#11 tokens. Packaged with Enterprise Server are
an NSS PKCS#11 token library (for the NSS Internal PKCS#11 Module, commonly known as
the NSS soft token) and NSS command-line management tools. For more details, see “Using
Use the NSS tools to create keys and certificates on PKCS#11 tokens and J2SE PKCS#11
providers to access token keys and certificates at runtime. A PKCS#11 provider is a
cryptographic service provider that acts as a wrapper around a native PKCS#11 library. A
PKCS#11 token generally refers to all the hardware and software tokens with a native PKCS#11
interface. A hardware token is a PKCS#11 token implemented in physical devices, such as
hardware accelerators and smart cards. A software token is a PKCS#11 token implemented
entirely in software.
Note – If you run Enterprise Server on the J2SE 1.4.x platform, only one PKCS#11 token, the NSS
soft token, is supported.

Using Hardware Crypto AcceleratorWith Enterprise Server
For the Microsoft Windows environment, add the location of NSS libraries AS_NSS and the
NSS tools directory, AS_NSS_BIN to the PATH environment variable. For simplicity, the
procedures described in this section use UNIX commands only. You should replace the UNIX
variables with the Windows variables, where appropriate.
Configuring the hardware crypto accelerators is divided into two main procedures:
■
■
Configuring PKCS#11Tokens
This section describes how to configure PKCS#11 tokens with the NSS security tool modutil.
Use the following procedure to configure a PKCS#11 token.
Enter the following command (all on one line):
modutil -dbdir AS_NSS_DB -nocertdb -force -add moduleName -libfile
absolute_path_of_pkcs11_library -mechanisms list_of_security_mechanisms
where, AS_NSS_DB is the NSS database directory (same as AS_DOMAIN_CONFIG when you use
the Domain Administration Server (DAS))
For example, to configure a hardware accelerator token, enter the following (all on one line):
modutil -dbdir AS_NSS_DB -nocertdb -force -add "Sun Crypto Accelerator" -libfile
/opt/SUNWconn/crypto/lib/libpkcs11.so -mechanisms RSA:DSA:RC4:DES
The hardware accelerator in this example is a SCA–1000 cryptographic accelerator. The
corresponding PKCS#11 library, by default, is located in
/opt/SUNWconn/crypto/lib/libpkcs11.so.
The mechanisms must be a complete list of the cryptographic mechanisms that are available in
the token. To use just a few of the available cryptographic mechanisms, see “Configuring J2SE
documentation on the NSS Security Tools site at
The examples that follow assume that the token name specified at token installation time is
mytoken.
To verify that the hardware accelerator is configured properly, enter the following command:
modutil -list -dbdir AS_NSS_DB
The standard output will look similar to the following:

For example, to list the contents of the default NSS soft token, type:
certutil -L -d AS_NSS_DB
The standard output will be similar to the following:

The output displays the name of the token in the left column and a set of three trust

the J2SE java.security.KeyStore API, which contains only one level of trust, the NSS
technology contains several levels of trust. Enterprise Server is primarily interested in the
first trust attribute, which describes how this token uses SSL. For this attribute:
T indicates that the Certificate Authority (CA) is trusted for issuing client certificates.
u indicates that you can use the certificates (and keys) for authentication or signing.
The attribute combination of u,u,u indicates that a private key exists in the database.
■
To list the contents of the hardware token, mytoken, run the following command:
certutil -L -d AS_NSS_DB -h mytoken
You will be prompted for the password for the hardware token. The standard output is

Caution – In Enterprise Server, do not modify the NSS password directly with the NSS tools
certutil and modutil. If you do so, security data in Enterprise Server might be corrupted.
Configuring J2SE 5.0 PKCS#11 Providers
Enterprise Server relies on J2SE PKCS#11 providers to access keys and certificates that are
located in PKCS#11 tokens at runtime. By default, Enterprise Server configures a J2SE PKCS#11
provider for the NSS soft token. This section describes how to override the default
configuration for the J2SE PKCS#11 provider.
In Enterprise Server, the following default PKCS#11 configuration parameters are generated for
each PKCS#11 token.
■
Configuration for the default NSS soft token:
name=internal
library=${com.sun.enterprise.nss.softokenLib}
nssArgs="configdir=’${com.sun.appserv.nss.db}’
certPrefix=’’ keyPrefix=’’ secmod=’secmod.db’"
slot=2
omitInitialize = true
■
Configuration for the SCA 1000 hardware accelerator:
name=HW1000
library=/opt/SUNWconn/crypto/lib/libpkcs11.so
slotListIndex=0
omitInitialize=true
These configurations conform to the syntax described in the Java PKCS#11 Reference Guide.
Note – The name parameter has no requirements other than that it must be unique. Certain
older versions of J2SE 5.0 support alphanumeric characters only.
You can override the default configuration parameters by creating a custom configuration file.
For example, you can explicitly disable the RSA Cipher and RSA Key Pair Generator in
SCA–1000. For details on disabling the RSA Cipher and RSA Key Pair Generator, see
124
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Using Hardware Crypto AcceleratorWith Enterprise Server
To create a custom configuration file:
1. Create a configuration file called as-install/mypkcs11.cfg with the following code and save
the file.
name=HW1000
library=/opt/SUNWconn/crypto/lib/libpkcs11.so
slotListIndex=0
disabledMechanisms = {
	CKM_RSA_PKCS
	CKM_RSA_PKCS_KEY_PAIR_GEN
}
omitInitialize=true
2. Update the NSS database, if necessary. In this case, update the NSS database so that it will
disable RSA.
Run the following command :
modutil -undefault "Sun Crypto Accelerator" -dbdir AS_NSS_DB -mechanisms RSA
The name of the algorithm on the mechanisms list differs from the one in the default
configuration. For a list of valid mechanisms in NSS, see the modutil documentation on the
NSS Security Tools site at
3. Update the server with this change by adding a property in the appropriate location, as
follows:
<property name="mytoken" value="&InstallDir;/mypkcs11.cfg"/>
The location for the property could be one of the following:
■
If the provider is for a DAS or server instance, add the property under the associated
<security-service>.
■
If the provider is for a node agent, add the property under the associated
<node-agent> element in the domain.xml file.
4. Restart the Enterprise Server.
The customized configurations will be in effect after the restart.

Configuring Message Security
Some of the material in this chapter assumes a basic understanding of security and web services
concepts. This chapter describes the configuration of message layer security for web services in
the Enterprise Server. This chapter contains the following topics:

Overview of Message Security
In message security, security information is inserted into messages so that it travels through the
networking layers and arrives with the message at the message destination(s). Message security
differs from transport layer security (which is discussed in the Security chapter of the Java EE
5.0 Tutorial) in that message security can be used to decouple message protection from message
transport so that messages remain protected after transmission.
Web Services Security: SOAP Message Security (WS-Security) is an international standard for
interoperable Web Services Security that was developed in OASIS by a collaboration of all the
major providers of web services technology (including Sun Microsystems). WS-Security is a
message security mechanism that uses XML Encryption and XML Digital Signature to secure
web services messages sent over SOAP. The WS-Security specification defines the use of various
security tokens including X.509 certificates, SAML assertions, and username/password tokens
to authenticate and encrypt SOAP web services messages.
The WS-Security specification can be viewed at
127
Understanding Message Security in the Enterprise Server
Understanding Message Security in the Enterprise Server
The Enterprise Server offers integrated support for the WS-Security standard in its web services
client and server-side containers. This functionality is integrated such that web services security
is enforced by the containers of the Enterprise Server on behalf of applications, and such that it
can be applied to protect any web service application without requiring changes to the
implementation of the application. The Enterprise Server achieves this effect by providing
facilities to bind SOAP layer message security providers and message protection policies to
containers and to applications deployed in containers.
Assigning Message Security Responsibilities
on page 129 roles are expected to take primary responsibility for configuring message security.
the typical case either of the other roles may secure an existing application without changing its
implementation without involving the developer. The responsibilities of the various roles are
defined in the following sections:
■
■
■
System Administrator
The system administrator is responsible for:
■
Configuring message security providers on the Enterprise Server.
■
Managing user databases.
■
Managing keystore and truststore files.
■
Configuring a Java Cryptography Extension (JCE) provider if using encryption and running
a version of the Java SDK prior to version 1.5.0.
■
Installing the samples server. This is only done if the xms sample application will be used to
demonstrate the use of message layer web services security.
A system administrator uses the Admin Console to manage server security settings and uses a
command line tool to manage certificate databases. In Platform Edition, certificates and private
keys are stored in key stores and are managed with keytool. Standard Edition and Enterprise
Edition store certificates and private keys in an NSS database, where they are managed using
certutil. This document is intended primarily for system administrators. For an overview of
message security tasks, see “Configuring the Enterprise Server for Message Security” on
128
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Understanding Message Security in the Enterprise Server
Application Deployer
The application deployer is responsible for:
■
Specifying (at application assembly) any required application-specific message protection
policies if such policies have not already been specified by upstream roles (the developer or
assembler).
■
Modifying Sun-specific deployment descriptors to specify application-specific message
protection policies information (message-security-binding elements) to web service
endpoint and service references.
Application Developer
The application developer can turn on message security, but is not responsible for doing so.
Message security can be set up by the System Administrator so that all web services are secured,
or by the Application Deployer when the provider or protection policy bound to the application
must be different from that bound to the container.
The application developer or assembler is responsible for the following:
■
Determining if an application-specific message protection policy is required by the
application. If so, ensuring that the required policy is specified at application assembly
which may be accomplished by communicating with the Application Deployer.
About SecurityTokens and Security Mechanisms
The WS-Security specification provides an extensible mechanism for using security tokens to
authenticate and encrypt SOAP web services messages. The SOAP layer message security
providers installed with the Enterprise Server may be used to employ username/password and
X.509 certificate security tokens to authenticate and encrypt SOAP web services messages.
Additional providers that employ other security tokens including SAML assertions will be
installed with subsequent releases of the Enterprise Server.
About UsernameTokens
The Enterprise Server uses Username tokens in SOAP messages to establish the authentication
identity of the message sender. The recipient of a message containing a Username token (within
embedded password) validates that the message sender is authorized to act as the user
(identified in the token) by confirming that the sender knows the secret (the password) of the
user.
When using a Username token, a valid user database must be configured on the Enterprise
Server
Chapter 10 • Configuring Message Security
129
Understanding Message Security in the Enterprise Server
About Digital Signatures
The Enterprise Server uses XML Digital signatures to bind an authentication identity to
message content. Clients use digital signatures to establish their caller identity, analogous to the
way basic authentication or SSL client certificate authentication have been used to do the same
thing when transport layer security is being used. Digital signatures are verified by the message
receiver to authenticate the source of the message content (which may be different from the
sender of the message.)
When using digital signatures, valid keystore and truststore files must be configured on the
Enterprise Server. For more information on this topic, read “About Certificate Files” on
About Encryption
The purpose of encryption is to modify the data such that it can only be understood by its
intended audience. This is accomplished by substituting an encrypted element for the original
content. When predicated on public key cryptography, encryption can be used to establish the
identity of the parties that can read a message.
When using Encryption, you must have an installed JCE provider that supports encryption. For
About Message Protection Policies
Message protection policies are defined for request message processing and response message
processing and are expressed in terms of requirements for source and/or recipient
authentication. A source authentication policy represents a requirement that the identity of the
entity that sent a message or that defined the content of a message be established in the message
such that it can be authenticated by the message receiver. A recipient authentication policy
represents a requirement that the message be sent such that the identity of the entities that can
receive the message can be established by the message sender. The providers apply specific
message security mechanisms to cause the message protection policies to be realized in the
context of SOAP web services messages.Request and response message protection policies are
defined when a provider is configured into a container. Application-specific message protection
policies (at the granularity of the web service port or operation) may also be configured within
the Sun-specific deployment descriptors of the application or application client. In any case,
where message protection policies are defined, the request and response message protection
policies of the client must match (be equivalent to) the request and response message protection
policies of the server. For more information on defining application-specific message
protection policies, refer to the Securing Applications chapter of the Developers Guide.

Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Understanding Message Security in the Enterprise Server
Glossary of Message SecurityTerminology
The terminology used in this document is described below. The concepts are also discussed in
■
Authentication Layer
The authentication layer is the message layer on which authentication processing must be
performed. The Enterprise Server enforces web services message security at the SOAP layer.
■
Authentication Provider
In this release of the Enterprise Server, the Enterprise Server invokes authentication
providers to process SOAP message layer security.
■
A client-side provider establishes (by signature or username/password) the source
identity of request messages and/or protects (by encryption) request messages such that
they can only be viewed by their intended recipients. A client-side provider also
establishes its container as an authorized recipient of a received response (by successfully
decrypting it) and validates passwords or signatures in the response to authenticate the
source identity associated with the response. Client-side providers configured in the
Enterprise Server can be used to protect the request messages sent and the response
messages received by server-side components (servlets and EJB components) acting as
clients of other services.
■
A server-side provider establishes its container as an authorized recipient of a received
request (by successfully decrypting it) and validates passwords or signatures in the
request to authenticate the source identity associated with the request. A server-side
provider also establishes (by signature or username/password) the source identity of
response messages and/or protects (by encryption) response messages such that they can
only be viewed by their intended recipients. Server-side providers are only invoked by
server-side containers.
■
Default Server Provider
The default server provider is used to identify the server provider to be invoked for any
application for which a specific server provider has not been bound. The default server
provider is sometimes referred to as the default provider.
■
Default Client Provider
The default client provider is used to identify the client provider to be invoked for any
application for which a specific client provider has not been bound.
■
Request Policy
The request policy defines the authentication policy requirements associated with request
processing performed by the authentication provider. Policies are expressed in message
sender order such that a requirement that encryption occur after content would mean that
the message receiver would expect to decrypt the message before validating the signature.
■
Response Policy
Chapter 10 • Configuring Message Security
131
Securing aWeb Service
The response policy defines the authentication policy requirements associated with response
processing performed by the authentication provider. Policies are expressed in message
sender order such that a requirement that encryption occur after content would mean that
the message receiver would expect to decrypt the message before validating the signature.
Securing aWeb Service
Web services deployed on the Enterprise Server are secured by binding SOAP layer message
security providers and message protection policies to the containers in which the applications
are deployed or to web service endpoints served by the applications. SOAP layer message
security functionality is configured in the client-side containers of the Enterprise Server by
binding SOAP layer message security providers and message protection policies to the client
containers or to the portable service references declared by client applications.
When the Enterprise Server is installed, SOAP layer message security providers are configured
in the client and server-side containers of the Enterprise Server, where they are available for
binding for use by the containers, or by individual applications or clients deployed in the
containers. During installation, the providers are configured with a simple message protection
policy that, if bound to a container, or to an application or client in a container, would cause the
source of the content in all request and response messages to be authenticated by XML digital
signature.
The administrative interfaces of the Enterprise Server can be employed to bind the existing
providers for use by the server-side containers of the Enterprise Server, to modify the message
protection policies enforced by the providers, or to create new provider configurations with
alternative message protection policies. Analogous administrative operations can be performed
on the SOAP message layer security configuration of the application client container as defined
By default, message layer security is disabled on the Enterprise Server. To configure message
layer security for the Enterprise Server follow the steps outlined in “Configuring the Enterprise

Once you have completed the above steps (which may include restarting the Enterprise Server),
web services security will be applied to all web services applications deployed on the Enterprise
Server.

Configuring the Enterprise Server for Message Security
Configuring Application-SpecificWeb Services
Security
Application-specific web services security functionality is configured (at application assembly)
by defining message-security-binding elements in the Sun-specific deployment descriptors of
the application. These message-security-binding elements are used to associate a specific
provider or message protection policy with a web services endpoint or service reference, and
may be qualified so that they apply to a specific port or method of the corresponding endpoint
or referenced service.
For more information on defining application specific message protection policies, refer to
Securing the Sample Application
The Enterprise Server ships with a sample application named xms. The xms application features
a simple web service that is implemented by both a J2EE EJB endpoint and a Java Servlet
endpoint. Both endpoints share the same service endpoint interface. The service endpoint
interface defines a single operation, sayHello, which takes a string argument, and returns a
String composed by pre-pending Hello to the invocation argument.
The xms sample application is provided to demonstrate the use of the Enterprise Server’s
WS-Security functionality to secure an existing web services application. The instructions
which accompany the sample describe how to enable the WS-Security functionality of the
Enterprise Server such that it is used to secure the xms application. The sample also
demonstrates the binding of WS-Security functionality directly to the application (as described
The xms sample application is installed in the directory:
as-install/samples/webservices/security/ejb/apps/xms/.

Configuring Other Security Facilities
The Enterprise Server implements message security using message security providers
integrated in its SOAP processing layer. The message security providers depend on other
security facilities of Enterprise Server.
1. If using a version of the Java SDK prior to version 1.5.0, and using encryption technology,
configure a JCE provider.
3. If using a username token, configure a user database, if necessary. When using a
username/password token, an appropriate realm must be configured and an appropriate
user database must be configured for the realm.
4. Manage certificates and private keys, if necessary.
AfterYou Finish
Once the facilities of the Enterprise Server are configured for use by message security providers,
then the providers installed with the Enterprise Server may be enabled as described in
Configuring a JCE Provider
The Java Cryptography Extension (JCE) provider included with J2SE 1.4.x does not support
RSA encryption. Because the XML Encryption defined by WS-Security is typically based on
RSA encryption, in order to use WS-Security to encrypt SOAP messages you must download
and install a JCE provider that supports RSA encryption.
Note – RSA is public-key encryption technology developed by RSA Data Security, Inc. The
acronym stands for Rivest, Shamir, and Adelman, the inventors of the technology.
Chapter 10 • Configuring Message Security
135
Configuring the Enterprise Server for Message Security
If you are running the Enterprise Server on version 1.5 of the Java SDK, the JCE provider is
already configured properly. If you are running the Enterprise Server on version 1.4.x of the
Java SDK, you can add a JCE provider statically as part of your JDK environment, as follows.
1. Download and install a JCE provider JAR (Java ARchive) file.
The following URL provides a list of JCE providers that support RSA encryption:
2. Copy the JCE provider JAR file to java-home/jre/lib/ext/.
3. Stop the Enterprise Server.
If the Enterprise Server is not stopped and then restarted later in this process, the JCE
provider will not be recognized by the Enterprise Server.
4. Edit the java-home/jre/lib/security/java.security properties file in any text editor.
Add the JCE provider you’ve just downloaded to this file.
The java.security file contains detailed instructions for adding this provider. Basically,
you need to add a line of the following format in a location with similar properties:
security.provider.n=provider-class-name
In this example, n is the order of preference to be used by the Enterprise Server when
evaluating security providers. Set n to 2 for the JCE provider you’ve just added.
For example, if you’ve downloaded The Legion of the Bouncy Castle JCE provider, you
would add this line.
security.provider.2=org.bouncycastle.jce.provider.
BouncyCastleProvider
Make sure that the Sun security provider remains at the highest preference, with a value of 1.
security.provider.1=sun.security.provider.Sun
Adjust the levels of the other security providers downward so that there is only one security
provider at each level.
The following is an example of a java.security file that provides the necessary JCE
provider and keeps the existing providers in the correct locations.
security.provider.1=sun.security.provider.Sun
security.provider.2=org.bouncycastle.jce.provider.
BouncyCastleProvider
security.provider.3=com.sun.net.ssl.internal.ssl.Provider
security.provider.4=com.sun.rsajca.Provider
security.provider.5=com.sun.crypto.provider.SunJCE
security.provider.6=sun.security.jgss.SunProvider
5. Save and close the file.

Message Security Setup
6. Restart the Enterprise Server.
Message Security Setup
Most of the steps for setting up the Enterprise Server for using message security can be
accomplished using the Admin Console, the asadmin command-line tool, or by manually
editing system files. In general, editing system files is discouraged due to the possibility of
making unintended changes that prevent the Enterprise Server from running properly,
therefore, where possible, steps for configuring the Enterprise Server using the Admin Console
are shown first, with the asadmin tool command shown after. Steps for manually editing system
files are shown only when there is no Admin Console or asadmin equivalent.
Support for message layer security is integrated into the Enterprise Server and its client
containers in the form of (pluggable) authentication modules. By default, message layer security
is disabled on the Enterprise Server. The following sections provide the details for enabling,
creating, editing, and deleting message security configurations and providers.

In most cases, it will be necessary to restart the Enterprise Server after performing the
administrative operations listed above. This is especially the case if you want the effects of the
administrative change to be applied to applications that were already deployed on the
Enterprise Server at the time the operation was performed.
Enabling Providers for Message Security
To enable message security for web services endpoints deployed in the Enterprise Server, you
must specify a provider to be used by default on the server side. If you enable a default provider
for message security, you also need to enable providers to be used by clients of the web services
deployed in the Enterprise Server. Information for enabling the providers used by clients is
To enable message security for web service invocations originating from deployed endpoints,
you must specify a default client provider. If you enabled a default client provider for the
Enterprise Server, you must ensure that any services invoked from endpoints deployed in the
Enterprise Server are compatibly configured for message layer security.
Use the command-line utility:

Configuring the Message Security Provider
Typically, a provider would be re-configured to modify its message protection policies,
although the provider type, implementation class, and provider-specific configuration
properties may also be modified.
Use the command-line utility to set the response policy, replace the word request in the
following commands with response.

Message Security Setup
Creating a Message Security Provider
To configure an existing provider using the Admin Console, select Configuration node > the
instance to Configure> Security node > Message Security node > SOAP node > Providers tab.
For more detailed instructions on creating a message security provider, see the Admin Console
online help.
Enabling Message Security for Application Clients
The message protection policies of client providers must be configured such that they are
equivalent to the message protection policies of the server-side providers they will be
interacting with. This is already the case for the providers configured (but not enabled) when
the Enterprise Server is installed.
To enable message security for client applications, modify the Enterprise Server specific
configuration for the application client container.
Setting the Request and Response Policy for the
Application Client Configuration
The request and response policies define the authentication policy requirements associated with
request and response processing performed by the authentication provider. Policies are
expressed in message sender order such that a requirement that encryption occur after content
would mean that the message receiver would expect to decrypt the message before validating
the signature.
To achieve message security, the request and response policies must be enabled on both the
server and client. When configuring the policies on the client and server, make sure that the
client policy matches the server policy for request/response protection at application-level
message binding.
To set the request policy for the application client configuration, modify the Enterprise Server
specific configuration for the application client container as described in “Enabling Message
the request-policy and response-policy elements as shown to set the request policy.
The other code is provided for reference. The other code may differ slightly in your installation.

Configuring the Diagnostic Service
The Diagnostic Service provides more visibility into and control of the runtime performance of
a server and its applications, allowing you to diagnose and isolate faults as they occur.
This chapter contains the following sections:
■
■
What is the Diagnostic Framework?
The Application Server Diagnostic Framework is a monitoring framework that defines and
implements a set of services that run within the application server standard life cycle. With the
Diagnostic Service, you can define, create, collect, and access diagnostic data generated by a
running server and the applications it deploys.
Diagnostic Service Framework
The diagnostic service reports configuration details for the application server instances. It is
useful for diagnosing application server problems such as exceptions, performance issues, and
other unexpected results. From within the Admin Console Diagnostic Service you can:
■
Compute Checksum: Collects checksum for selective Application Server binary files under
appserver_install_dir/ lib, appserver_install_dir/etc and
appserver_install_dir/bin directory
■
Verify Configuration: Captures configuration files such as, domain.xml, server.policy.
■
Capture Install Log: Installation specific details such as Application Server version number
or patch ID and contents of log file generated at the time of installation. Absolute path for
installation directory is used to determine which Installer log file is collected if there are
multiple installations on the same machine. The contents of config/asenv.conf is copied
from the installation folder for DAS as well as node agents.
141
Diagnostic Service Framework
Installation specific details are collected only for file-based installations.
■
Capture System Information: The following system information is collected by default:
■
Network Settings
■
OS details
■
Hardware information
Data collected using native code is not available on the Platform Edition of Application
Server.
■
Capture Application Deployment Descriptor: Deployment descriptors such as
ejb-jar.xml, sun-ejb-jar.xml, web.xml, sun-web.xml, and sun-sip.xml
■
■
Log Level:
Log Entries:
The number of log entries to be included in the generated diagnostic report.
Generating a Diagnostic Report
Generating a diagnostic report is based on the preferences you set in the Application Server
Diagnostic tab in the Administration Console. Confidential data appears in the generated
report as listed in the Confidential Properties table.

Transactions
By enclosing one or more steps in an indivisible unit of work, a transaction ensures data
integrity and consistency. This chapter contains the following sections:
■
■
AboutTransactions
■
■
■
What is aTransaction?
A transaction is a series of discreet actions in an application that must all complete successfully
or else all the changes in each action are backed out. For example, to transfer funds from a
checking account to a savings account is a transaction with the following steps:
1. Check to see if the checking account has enough money to cover the transfer.
2. If there’s enough money in the checking account debit the amount from the checking
account.
3. Credit the money to the savings account.
4. Record the transfer to the checking account log.
5. Record the transfer to the savings account log.
If any of these steps fails, all changes from the preceding steps must be backed out, and the
checking account and savings account must be in the same state as they were before the
transaction started. This event is called a rollback. If all the steps complete successfully, the
transaction is in a committed state. Transactions end in either a commit or a rollback.

Transactions in Java EETechnology
Transaction processing involves the following five participants:
■
Transaction Manager
■
Enterprise Server
■
Resource Manager(s)
■
Resource Adapter(s)
■
User Application.
Each of these entities contribute to reliable transaction processing by implementing the
different APIs and functionalities, discussed below:
■
The Transaction Manager provides the services and management functions required to
support transaction demarcation, transactional resource management, synchronization,
and transaction context propagation.
■
The Enterprise Server provides the infrastructure required to support the application
runtime environment that includes transaction state management.
■
The Resource Manager (through a resource adapter) provides the application access to
resources. The resource manager participates in distributed transactions by implementing a
transaction resource interface used by the transaction manager to communicate transaction
association, transaction completion and recovery work. An example of such a resource
manager is a relational database server.
■
A Resource Adapter is a system level software library that is used by the application server or
client to connect to a Resource Manager. A Resource Adapter is typically specific to a
Resource Manager. It is available as a library and is used within the address space of the
client using it. An example of such a resource adapter is a JDBC driver.
■
A Transactional User Application developed to operate in an application server
environment looks up transactional data sources and, optionally, the transaction manager,
using JNDI. The application may use declarative transaction attribute settings for enterprise
beans or explicit programmatic transaction demarcation.

Workarounds for Specific Databases
The Enterprise Server provides workarounds for some known issues with the recovery
implementations of the following JDBC drivers. These workarounds are used unless explicitly
disabled.
■
Oracle thin driver - The XAResource.recover method repeatedly returns the same set of
in-doubt Xids regardless of the input flag. According to the XA specifications, the
Transaction Manager initially calls this method with TMSTARTSCAN and then with
TMNOFLAGS repeatedly until no Xids are returned. The XAResource.commit method also
has some issues.
To disable the Enterprise Server workaround, set the oracle-xa-recovery-workaround
Note – These workarounds do not imply support for any particular JDBC driver.

To configure how the Enterprise Server recovers from transactions
Transactions might be incomplete either because the server crashed or a resource manager
crashed. It is essential to complete these stranded transactions and recover from the failures.
Enterprise Server is designed to recover from these failures and complete the transactions upon
server startup.
While performing the recovery, if some of the resources are unreachable the server restart may
be delayed as it tries to recover the transactions.
Chapter 12 • Transactions
145
Admin ConsoleTasks forTransactions
When the transaction spans across servers, the server that started the transaction can contact
the other servers to get the outcome of the transactions. If the other servers are unreachable, the
transaction uses the Heuristic Decision field to determine the outcome.

To set the keypoint interval
Keypoint operations compress the transaction log file. The keypoint interval is the number of
transactions between keypoint operations on the log. Keypoint operations can reduce the size of
the transaction log files. A larger number of keypoint intervals (for example, 2048) results in
larger transaction log files, but fewer keypoint operations, and potentially better performance.
A smaller keypoint interval (for example, 256) results in smaller log files but slightly reduced
performance due to the greater frequency of keypoint operations.

Configuring the HTTP Service
The HTTP service is the component of the Enterprise Server that provides facilities for
deploying web applications and for making deployed web applications accessible by HTTP
clients. These facilities are provided by means of two kinds of related objects, virtual servers and
HTTP listeners.
This chapter discusses the following topics:
■
■
Virtual Servers
A virtual server, sometimes called a virtual host, is an object that allows the same physical server
to host multiple Internet domain names. All virtual servers hosted on the same physical server
share the Internet Protocol (IP) address of that physical server. A virtual server associates a
domain name for a server (such as www.aaa.com) with the particular server on which the
Enterprise Server is running.
Note – Do not confuse an Internet domain with the administrative domain of the Enterprise
Server.
For instance, assume you want to host these domains on your physical server:
www.aaa.com
www.bbb.com
www.ccc.com
Assume also that www.aaa.com, www.bbb.com, and www.ccc.com have web modules web1, web2,
and web3, respectively, associated with them.
This means that all of these URLs are handled by your physical server:
149
HTTP Listeners
http://www.aaa.com:8080/web1
http://www.bbb.com:8080/web2
http://www.ccc.com:8080/web3
The first URL is mapped to virtual host www.aaa.com, the second URL is mapped to virtual host
www.bbb.com, and the third is mapped to virtual host www.ccc.com.
On the other hand, the following URL results in a 404 return code, because web3 isn’t registered
with www.bbb.com:
http://www.bbb.com:8080/web3
For this mapping to work, make sure that www.aaa.com, www.bbb.com, and www.ccc.com all
resolve to your physical server’s IP address. They need to be registered with the DNS server for
your network. In addition, on a UNIX system, add these domains to your /etc/hosts file (if the
setting for hosts in your /etc/nsswitch.conf file includes files).
When the Enterprise Server is started, it starts the following virtual servers automatically:
■
A virtual server named server, which hosts all user-defined web modules
■
A virtual server named __asadmin, which hosts all administration-related web modules
(specifically, the Admin Console). This server is restricted; you cannot deploy web modules
to this virtual server.
For development, testing, and deployment of web services in a non-production environment,
server is often the only virtual server required. In a production environment, additional virtual
servers provide hosting facilities for users and customers so that each appears to have its own
web server, even though there is only one physical server.
HTTP Listeners
Each virtual server provides connections between the server and clients through one or more
HTTP listeners. Each HTTP listener is a listen socket that has an IP address, a port number, a
server name, and a default virtual server.
HTTP listeners must have a unique combination of port number and IP address. For example,
an HTTP listener can listen on all configured IP addresses on a given port for a machine by
specifying the IP address 0.0.0.0. Alternatively, the HTTP listener can specify a unique IP
address for each listener, but use the same port.
Since an HTTP listener is a combination of IP address and port number, you can have multiple
HTTP listeners with the same IP address and different port numbers (for example, 1.1.1.1:8081
and 1.1.1.1:8082), or with different IP addresses and the same port number (for example,
1.1.1.1:8081 and 1.2.3.4:8081, if your machine was configured to respond to both these
addresses).
150
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
HTTP Listeners
However, if an HTTP listener uses the 0.0.0.0 IP address, which listens on all IP addresses on a
port, you cannot create HTTP listeners for additional IP addresses that listen on the same port
for a specific IP address. For example, if an HTTP listener uses 0.0.0.0:8080 (all IP addresses on
port 8080), another HTTP listener cannot use 1.2.3.4:8080.
Because the system running the Enterprise Server typically has access to only one IP address,
HTTP listeners typically use the 0.0.0.0 IP address and different port numbers, with each port
number serving a different purpose. If the system does have access to more than one IP address,
each address can serve a different purpose.
By default, when the Enterprise Server starts, it has the following HTTP listeners:
■
Two HTTP listeners named http-listener-1 and http-listener-2, associated with the
virtual server named server. The listener named http-listener-1 does not have security
enabled; http-listener-2 has security enabled.
■
An HTTP listener named admin-listener, associated with the virtual server named
__asadmin. This listener hasdoes not have security enabled.
All these listeners use the IP address 0.0.0.0 and the port numbers specified as the HTTP server
port numbers during installation of the Enterprise Server. If the Enterprise Server uses the
default port number values, http-listener-1 uses port 8080, http-listener-2 uses port
8181, and admin-listener uses port 48489.
Each HTTP listener has a default virtual server. The default virtual server is the server to which
the HTTP listener routes all request URLs whose host component does not match any of the
virtual servers that are associated with the HTTP listener (a virtual server is associated with an
HTTP listener by listing the HTTP listener in its http-listeners attribute).
In addition, specify the number of acceptor threads in the HTTP listener. Acceptor threads are
threads that wait for connections. The threads accept connections and put them in a queue,
called the connection queue, where they are then picked up by worker threads. Configure
enough acceptor threads so that there is always one available when a new request comes in, but
few enough so that they do not provide too much of a burden on the system. In the Enterprise
Server, there is no distinction between acceptor and request processing (worker) threads: each
HTTP listener thread is responsible for accepting and processing requests. For this reason, the
HTTP listeners in the Enterprise Server’s default configuration use 50 acceptor threads. The
connection queue includes both the new connections just accepted by acceptor threads and
persistent connections managed by the Keep-Alive connection management subsystem.
A set of request processing threads retrieves incoming HTTP requests from the connection
queue and processes the requests. These threads parse the HTTP headers, select the appropriate
virtual server, and run through the request processing engine to service the request. When there
are no more requests to process, but the connection can be kept persistent (either by using
HTTP/1.1 or sending a Connection: keep-alive header), the request processing thread
assumes the connection to be idle and passes the connection to the Keep-Alive connection
management subsystem.
Chapter 13 • Configuring the HTTP Service
151
HTTP Listeners
The Keep-Alive subsystem periodically polls such idle connections and queues those
connections with activity into the connection queue for future processing. From there, a request
processing thread again retrieves the connection and processes its request. The Keep-Alive
subsystem is multi-threaded, as it manages potentially tens of thousands of connections.
Efficient polling techniques are used, by dividing the number of connections into smaller
subsets, to determine which connections are ready with requests and which of those
connections have idled for sufficient time to deem them closed (beyond a maximum
permissible Keep-Alive timeout).
The HTTP listener’s server name is the host name that appears in the URLs the server sends to
the client as part of a redirect. This attribute affects URLs the server automatically generates; it
does not affect the URLs for directories and files stored in the server. This name is normally the
alias name if the server uses an alias. If a client sends a Host: header, that host name supersedes
the HTTP listener’s server name value in redirects.
Specify a redirect port to use a different port number from that specified in the original request.
A redirect occurs in one of these situations:
■
If a client tries to access a resource that no longer exists at the specified URL (that is, the
resource has moved to another location), the server redirects the client to the new location
(instead of returning a 404), by returning a designated response code and including the new
location in the response’s Location header.
■
If a client tries to access a resource that is protected (for example, SSL) on the regular HTTP
port, the server redirects the request to the SSL-enabled port. In this case, the server returns
a new URL in the Location response header, in which the original insecure port has been
replaced with the SSL-enabled port. The client then connects to this new URL.
Specify also whether security is enabled for an HTTP listener and what kind of security is used
(for example, which SSL protocol and which ciphers).
To access a web application deployed on the Enterprise Server, use the URL
http://localhost:8080/ (or https://localhost:8181/ if it is a secure application), along
with the context root specified for the web application. To access the Admin Console, use the
URL https://localhost:4848/ or http://localhost:4848/asadmin/ (its default context
root).
Because a virtual server must specify an existing HTTP listener, and because it cannot specify an
HTTP listener that is already being used by another virtual server, create at least one HTTP
listener before creating a new virtual server.

Overview ofWeb Services
A web service is an application accessed by clients using XML-based protocols, such as Simple
Object Access Protocol (SOAP), sent over internet protocols, such as HTTP. Clients access a
web service application through its interfaces and bindings, defined using XML artifacts such as
a web services Definition Language (WSDL) file.
The eXtensible Markup Language (XML) is a standard developed by the World Wide Web
Consortium (W3C) and is one of the foundations on which web services are built. XML enables
web services and clients to communicate with each other in a common language. XML is a
153
Overview ofWeb Services
simple, flexible, text-based markup language. XML data is marked using tags enclosed in angled
brackets. The tags contain the meaning of the data they mark. Such markup allows different
systems to easily exchange data with each other.
A Document Type Definition (DTD) or XML Schema Definition (XSD) describes the structure
of an XML document. It has information on the tags the corresponding XML document can
have, the order of those tags, and so forth.
XSLT, which stands for eXtensible Stylesheet Language Transformation, is used for
transforming XML documents from one format to another.
Web Services Standards
Simple Object Access Protocol (SOAP) provides a common messaging format for web services.
SOAP enables objects not known to one another to exchange messages. SOAP uses an
XML-based data encoding format and HTTP to transport messages. SOAP is independent of
both the programming language and the operational platform, and it does not require any
specific technology at its endpoints
Universal Description, Discovery, and Integration (UDDI) provides a standard way to register,
de-register, and look up web services. Similar to a telephone system's yellow pages, a UDDI
registry's enables providers to register their services and requestors to find services. Once a
requestor finds a service, the registry has no more role to play between the requestor and the
provider.
Web Services Description Language (WSDL) defines a standard way to specify the details of a
web service. It is a general-purpose XML schema that can specifies details of web service
interfaces, bindings, and other deployment details. By having such a standard way to specify
details of a service, clients who have no prior knowledge of a web service can use it.
ebXML (Electronic Business using eXtensible Markup Language) is a set of specifications that
Advancement of Structured Information Standards) controls the ebXML specifications.
Java EEWeb Service Standards
Java APIs for XML processing (JAXP) is a vendor-neutral set of lightweight APIs for parsing or
processing XML documents. JAXP enables a web service to “plug in” any conforming XML
parser. If no external parser is “plugged in,” then JAXP uses its own XML parser
implementation.
Java API for XML-based remote procedure calls (JAX-RPC) uses an XML-based protocol for
client-server remote procedure calls . JAX-RPC enables SOAP-based interoperable and portable
web services. Developers use the JAX-RPC programming model to develop SOAP-based web
154
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Deploying andTestingWeb Services
service endpoints, along with corresponding WSDL descriptions, and clients. A JAX-RPC
based web service can interact with clients that are not based on Java. Similarly, a JAX-RPC
based client can interact with a non-Java-based web service implementation.
Java API for XML registries (JAXR), a Java API for accessing business registries, has a flexible
architecture that supports UDDI, and other registry specifications (such as ebXML). A JAXR
client, which can be a stand-alone Java application or a J2EE component, uses an
implementation of the JAXR API provided by a JAXR provider to access business registries. A
JAXR provider consists of two parts: a registry--specific JAXR provider, which provides a
registry-specific implementation of the API, and a JAXR pluggable provider, which implements
those features of the API that are independent of the type of registry. The pluggable provider
hides the details of registry-specific providers from clients.
SOAP with Attachments API for Java (SAAJ) enables developers to produce and consume
messages conforming to the SOAP 1.1 specification and SOAP with Attachments note. SAAJ
provides an abstraction for handling SOAP messages with attachments. Advanced developers
can use SAAJ to have their applications operate directly with SOAP messages. Attachments may
be complete XML documents, XML fragments, or MIME-type attachments. In addition, SAAJ
allows developers to enable support for other MIME types. JAX technologies, such as JAX-RPC,
internally use SAAJ to hide SOAP complexities from developers. SAAJ enables:
■
Synchronous request-response messaging: the client sends a message and then waits for the
response.
■
One-way asynchronous messaging: the client sends a message and continues with its
processing without waiting for a response.
Deploying andTestingWeb Services
Enterprise Server enables you to easily deploy and test web services.
DeployingWeb Services
Deploy a web service in an enterprise archive (EAR) just as you would an enterprise application.
A web service can also be implemented by a POJO (plain old Java Object). Deploy a POJO web
service using the auto-deploy feature by dragging and dropping it into the auto-deploy
directory. Enterprise Server will automatically generate the appropriate web XML files and
deploy the web service.
In Admin Console, you can view a list of deployed web services under Application Server > Web
Services | General.

TestingWeb Services
Admin Console enables you to test web services and diagnose problems. You can ping a
deployed web service with a generic test Servlet. SOAP messages are displayed for each method
invocation.
To test a web service with Admin Console, select Applications > Web Services >
web-service-name | General, then click the Test button.
Web Services Security
Support for SOAP message layer security is based on the SAML token profile of WS-Security.
Tamper-proof auditing for Web services is also provided.
UsingWeb Services Registries
Note – Enterprise Server does not have an internal registry. To publish web services to an
internal registry, you must download and install the registry on the application server. To
publish a web service to an external registry, specify the address of the external registry.

UsingWeb Services Registries
Adding a Registry
Add or remove a web services registry with Admin Console at Application Server > Web
Services | Registry. Use this page to create a Registry Access Point (RAP). When you add a
registry, specify the following paramters:
■
JNDI Name: the connection resource pool (JNDI) name of the registry. The JNDI Name of
this connector resource is the JNDI Name of the registry.
■
Choose the type of the registry to add: UDDI 3.0 or ebXML.
■
Publish URL and Query URL: the addresses for publishing and querying the registry,
respectively. The format is: http://<hostname>/<path of registry installation>.
■
User name and password for the registry.
The registry JNDI Name is created as a result of the following steps:
■
A resource adapter is created that can talk to the registry.
■
In the application server context, a JAXR resource adapter comes preconfigured to talk to a
UDDI registry. You can also download a SOA registry resource adapter module. The SOA
registry is the Sun specific ebXML registry.
■
Create a connection resource pool using the resource adapter.
■
Create a connector resource using this connection pool.
Publishing aWeb Service to a Registry
To publish a web service with Admin Console, select Applications > Web Services >
web-service-name | Publish.
In the Publish Web Service screen, select one or more registries to which you want to publish
the web service, then click Publish. To publish to all the available registries, click the Add All
button.
Enter categories under which this web service will show up in the registry. Use a comma to
separate each category. The categories are defined in the registry you are using. Enter a
description for this web service. Enter the name of the organization, if you are publishing to a
UDDI registry.
If you are using a load balancer, enter the Load Balancer host name, port number, and the SSL
port number. If you are publishing the web service to an external registry, where the WSDL can
be found over the internet, these options will replace the hostname and port name specified in
the WSDL to the one of the load balancer.
To un-publish a web service, In the Publish Web Service screen, select the registry from which
you want to unpublish the web service, then click Unpublish.

Transforming Messages with XSLT Filters
Transforming Messages with XSLT Filters
You can apply XSLT transformation rules to a web service end point. This enables fine-grained
control of web service requests and responses. You can apply multiple XSLT rules to a web
service end point method, and you can configure the order in which you apply the
transformations. All the XSLT files are stored in the generated/xml/appOrModule directory of
the central repository. These transformation rules are synchronized to the remote server
instances.
You can apply transformation rule to a SOAP request or response.
To add a transformation rule to apply to a web service operation with Admin Console, select
Applications > Web Services > web-service-name | Transformation. Click Add.
A list of transformation rule available for this web service end point is displayed.
Browse to the location of the XSLT file that contains the transformation rule. All the generated
XSLT files are stored in the generated/xml/application or module name/ directory.
If you add multiple transformation rules for a web service endpoint, the transformation rules
are applied in the order in which they are added.
To enable a transformation rule, in the Transformation Rules page select the check box
corresponding to the rule, then click Enable. To disable the a rule, click Disable.
To remove a transformation rule, in the Transformation Rules page select the check box
corresponding to the rule, then click Remove. This removes the transformation rule from the
list. If this transformation rule is applied to a web service endpoint, it is automatically disabled.
However, the XSLT file remains in the file path location. Other web service endpoints can use
this XSLT file.
MonitoringWeb Services
Admin console can track and graphically display operational statistics for web services, and can
display messages sent and received by web services.
To enable monitoring for a web service, with Admin Console, select Applications > Web
Services > web-service-name | Monitor | Configuration.
In the Monitoring Configuration page, set the monitoring level:
■
LOW- Monitors response time, throughput, total number of requests, and faults for the web
service. Does not perform method-level monitoring.
■
HIGH- Adds message tracing and monitoring of number of requests per second, average
response time, and throughput attributes.

Configuring the Object Request Broker
This chapter describes how to configure the Object Request Broker (ORB) and IIOP listeners. It
has the following sections:
■
■
■
An Overview of the Object Request Broker
■
■
■
CORBA
The Enterprise Server supports a standard set of protocols and formats that ensure
interoperability. Among these protocols are those defined by CORBA.
The CORBA (Common Object Request Broker Architecture) model is based on clients
requesting services from distributed objects or servers through a well-defined interface by
issuing requests to the objects in the form of remote method requests. A remote method request
carries information about the operation that needs to be performed, including the object name
(called an object reference) of the service provider and parameters, if any, for the invoked
method. CORBA automatically handles network programming tasks such as object
registration, object location, object activation, request de-multiplexing, error-handling,
marshalling, and operation dispatching.
161
Configuring the ORB
What is the ORB?
The Object Request Broker (ORB) is the central component of CORBA. The ORB provides the
required infrastructure to identify and locate objects, handle connection management, deliver
data, and request communication.
A CORBA object never talks directly with another. Instead, the object makes requests through a
remote stub to the ORB running on the local machine. The local ORB then passes the request to
an ORB on the other machine using the Internet Inter-Orb Protocol (IIOP for short). The
remote ORB then locates the appropriate object, processes the request, and returns the results.
IIOP can be used as a Remote Method Invocation (RMI) protocol by applications or objects
using RMI-IIOP. Remote clients of enterprise beans (EJB modules) communicate with the
Enterprise Server via RMI-IIOP.
IIOP Listeners
An IIOP listener is a listen socket that accepts incoming connections from the remote clients of
enterprise beans and from other CORBA-based clients. Multiple IIOP listeners can be
configured for the Enterprise Server. For each listener, specify a port number, a network
address, and optionally, security attributes.
Configuring the ORB
To configure ORB, in the Admin Console, click the Configuration tab. Click the ORB tab
corresponding to the instance you want to configure.
Managing IIOP Listeners
To create, edit and delete IIOP listeners, click the Configuration tab in the Admin Console.
Click the ORB tab corresponding to the instance you want to configure. Select the IIOP
Listeners tab. For more detailed instructions, consult the Admin Console Online Help.

Thread Pools
The Java Virtual Machine (JVM) can support many threads of execution at once. To help
performance, the Enterprise Server maintains one or more thread pools. It is possible to assign
specific thread pools to connector modules and to the ORB.
One thread pool can serve multiple connector modules and enterprise beans. Request threads
handle user requests for application components. When the server receives a request, it assigns
the request to a free thread from the thread pool. The thread executes the client's requests and
returns results. For example, if the request needs to use a system resource that is currently busy,
the thread waits until that resource is free before allowing the request to use that resource.
Specify the minimum and maximum number of threads that are reserved for requests from
applications. The thread pool is dynamically adjusted between these two values. The minimum
thread pool size that is specified signals the server to allocate at least that many threads in
reserve for application requests. That number is increased up to the maximum thread pool size
that is specified.
Increasing the number of threads available to a process allows the process to respond to more
application requests simultaneously.
Avoid thread starvation, where one resource adapter or application occupies all threads in the
Enterprise Server, by dividing the Enterprise Server threads into different thread-pools.
This chapter contains the following topics:
■

Working withThread Pools
Working withThread Pools
To create a thread pool using the Admin Console, go to Configuration > Thread Pools >
Current Pools > New.
■
Enter the name of the thread pool in the Thread Pool ID field.
■
Enter the minimum number of threads in the thread pool servicing requests in this queue in
the Minimum Thread Pool Size field.
These threads are created up front when this thread pool is instantiated.
■
Enter the maximum number of threads in the thread pool servicing requests in this queue in
the Maximum Thread Pool Size field.
This is the upper limit on the number of threads that exist in the thread pool.
■
Enter the number, in seconds, after which idle threads are removed from pool in the Idle
Timeout field.
■
Enter the total number of work queues that are serviced by this thread pool in the Number
of Work Queues field.
■

For more details on creating thread pools, click Help in the Admin Console.
You can also create a thread pool from the command-line by using the asadmin command,
create-threadpool.
To edit a settings for a thread pool using the Admin Console, go to Configuration > Thread
Pools > Current Pools and select the pool you want to configure. Modify the values for the
selected thread pool, save and restart the Enterprise Server.
For more details on editing thread pools, click Help in the Admin Console.
To delete a thread pool using the Admin Console, go to Configuration > Thread Pools >
Current Pools. Check the thread pool name to be deleted and click Delete.

Configuring Logging
This chapter briefly describes how to configure logging and view the server log. It contains the
following sections:
■
■
About Logging
■
■
Log Records
The Enterprise Server uses the Java EE platform Logging API specified in JSR 047. Enterprise
Server logging messages are recorded in the server log, normally found at
domain-dir/logs/server.log. When a log is rotated, Enterprise Server creates a new, empty
file named server.log and renames the old file server.log_date, where date is the date and
time when the file was rotated.
The components of the Enterprise Server generate logging output. Application components can
also generate logging output.
Application components may use the Apache Commons Logging Library to log messages. The
platform standard JSR 047 API, however, is recommended for better log configuration.
Log records follow a uniform format:
[#|yyyy-mm-ddThh:mm:ss.SSS-Z|Log Level|ProductName-Version|LoggerName|Key Value Pairs|Message|#]
For example:
165
About Logging
[#|2006-10-21T13:25:53.852-0400|INFO|sun-appserver9.1|javax.enterprise.
system.core|_ThreadID=13;|CORE5004: Resource Deployed:
[cr:jms/DurableConnectionFactory].|#]
In this example,
■
[# and #] mark the beginning and end of the record.
■
The vertical bar (|) separates the record fields.
■
2006-10-21T13:25:53.852-0400 specifies the date and time.
■
The Log Level is INFO. This level may have any of the following values: SEVERE, WARNING,
INFO, CONFIG, FINE, FINER, and FINEST.
■
The ProductName-Version is sun-glassfish-comms-server1.0.
■
The LoggerName is a hierarchical logger namespace that identifies the source of the log
module, in this case javax.enterprise.system.core.
■
The Key Value Pairs are key names and values, typically a thread ID such as _ThreadID=14;.
■
The Message is the text of the log message. For all Enterprise Server SEVERE and WARNING
messages and many INFO messages, it begins with a message ID that consists of a module
code and a numerical value (in this case, CORE5004).
The log record format might be changed or enhanced in future releases.
The Logger Namespace Hierarchy
The Enterprise Server provides a logger for each of its modules. The following table lists the
names of the modules and the namespace for each logger in alphabetical order, as they appear

■
Instance Name — Choose an instance name from the drop-down list to view the log for that
server instance. The default is the current server instance.
■
Log File — Choose a log file name from the drop-down list to view the contents of that log.
The default is server.log.
■
Timestamp — To view the most recent messages, select Most Recent (the default). To view
messages only from a certain period of time, select Specific Range and type a date and time
value in the From and To fields that appear. For the Time value, the syntax must take the
following form (SSS stands for milliseconds):
hh:mm:ss.SSS
For example:
17:10:00.000
If the From value is later than the To value, an error message appears.
■
Log Level — To filter messages by log level, choose a log level from the drop-down list. By
default, the display includes all messages that appear in the server log at the chosen log level
and more severe levels. Select the checkbox labeled “Do not include more severe messages”
to display messages at only the chosen level.

and so on.
■
Custom Logger — To view messages from loggers specific to a particular application, type
the logger names in the text field, one per line. If the application has several modules, you
can view any or all of them. For example, suppose the application has loggers with the
following names:
com.mycompany.myapp.module1
com.mycompany.myapp.module2
com.mycompany.myapp.module3
To view messages from all modules in the application, type com.mycompany.myapp. To view
messages from module2 only, type com.mycompany.myapp.module2.
When you specify one or more custom loggers, messages from Enterprise Server modules
appear only if you specify them explicitly in the Logger area.
■
Name-Value Pairs — To view output from a specific thread, type the key name and value
for that thread in the text field. The key name is _ThreadID. For example:
_ThreadID=13

Monitoring in the Enterprise Server
Use monitoring to observe the runtime state of various components and services deployed in a
server instance of theEnterprise Server. With the information on the state of runtime
components and processes, it is possible to identify performance bottlenecks for tuning
purposes, aid capacity planning, predict failures, do root cause analysis in case of failures, and
ensure that everything is functioning as expected.
Turning monitoring on reduces performance by increasing overhead.
You can also use management rules to alert you of potential problems with your server, and
optionally take action when the server reaches certain performance thresholds. For more

Overview of Monitoring
To monitor the Enterprise Server, perform these steps:
1. Enable the monitoring of specific services and components using either the Admin Console
or the asadmin tool.
For more information on this step, refer to “Enabling and Disabling Monitoring” on
2. View monitoring data for the specified services or components using either the Admin
Console or the asadmin tool.
About theTree Structure of Monitorable Objects
The Enterprise Server uses a tree structure to track monitorable objects. Because the tree of
monitoring objects is dynamic, it changes as components are added, updated, or removed in the
instance. The root object in the tree is the server instance name, for example, server. (In the
Platform Edition, just one server instance is permitted.)
The following command displays the top level of the tree:
asadmin> list --user adminuser --monitor server

By default, monitoring is turned off for all components and services. To turn monitoring on,
select LOW or HIGH from the combo box. To turn monitoring off, select OFF from the combo
box.
For details on configuring monitoring, see the online help available with the Admin Console.
▼
To Configure Monitoring Levels Using asadmin
1
Use the get command to find out what services and components currently have monitoring
enabled.
asadmin> get --user admin-user server.monitoring-service.module-monitoring-levels.*
Returns:
server.monitoring-service.module-monitoring-levels.
connector-connection-pool = OFF

To Use the asadmin monitor Command toView Monitoring Data
asadmin has two ways of viewing monitoring data. The first is to use the monitor command.
This command prints out the commonly-monitored statistics, and has options for filtering out
statistics and capture the output in a Comma Separated Values (CSV) file.
1
To view monitoring data, use the monitor command, and specify the type of monitoring data:
httplistener, keepalive, filecache, connectionqueue, jdbcpool, jvm, threadpool,

servlet, connection, connectorpool, endpoint, entitybean, messagedriven,

To view monitoring data and send the output to a CSV file, use the filename option. For
example:
asadmin> monitor --type jvm --filename myoutputfile --user adminuser server
▼
To Use the asadmin get and list Commands toView Monitoring Data
The monitor command is useful in most situations. However, it does not offer the complete list
of all monitorable objects. To view all monitorable data using the asadmin tool, use the asadmin
list and asadmin get commands followed by the dotted name of a monitorable object, as
follows.
1
To view the names of the objects that can be monitored, use the asadmin list command.
For example, to view a list of application components and subsystems that have monitoring
enable for the server instance, type the following command in a terminal window:
asadmin> list --user adminuser --monitor server
The preceding command returns a list of application components and subsystems that have
monitoring enabled, for example:
server.resources
server.connector-service
server.orb
server.jms-service
server.jvm
server.applications
server.http-service
server.sip-service
server.thread-pools

To display monitoring statistics for an application component or subsystem for which
monitoring has been enabled, use the asadmin get command.
To get the statistics, type the asadmin get command in a terminal window, specifying a name
displayed by the list command in the preceding step. The following example attempts to get
all attributes from a subsystem for a specific object:
asadmin> get --user adminuser --monitor server.jvm.*

Understanding and Specifying Dotted Names
In the asadmin list and get commands, specify the dotted name of monitorable objects. All
child objects are addressed using the dot (.) character as separator, thus these are referred to as
dotted names. If a child node is of singleton type, then only the monitoring object type is needed
to address the object, otherwise a name of the form type.name is needed to address the object.
For example, http-service is one of the valid monitorable object types and is a singleton. To
address a singleton child node representing the http-service of instance server, the dotted
name is:
server.http-service
Chapter 18 • Monitoring Components and Services
195
Viewing Monitoring Data
Another example, application, is a valid monitorable object type and is not a singleton. To
address a non-singleton child node representing, for example, the application PetStore, the
dotted name is:
server.applications.petstore
The dotted names can also address specific attributes in monitorable objects. For example,
http-service has a monitorable attribute called bytesreceived-lastsampletime. The
following name addresses the bytesreceived attribute:
server.http-service.server.http-listener-1.
bytesreceived-lastsampletime
The administrator is not expected to know the valid dotted names for asadmin list and get
commands. The list command displays available monitorable objects, while the get
command used with a wildcard parameter allows the inspection of all available attributes on
any monitorable object.
The underlying assumptions for using the list and get commands with dotted names are:
■
Any list command that has a dotted name that is not followed by a wildcard (*) gets as its
result the current node’s immediate children. For example, list --user adminuser
--monitor server lists all immediate children belonging to the server node.
■
Any list command that has a dotted name followed by a wildcard of the form .* gets as its
result a hierarchical tree of children nodes from the current node. For example, list
--user adminuser --monitor server.applications.* lists all children of applications
and their subsequent child nodes and so on.
■
Any list command that has a dotted name preceded or followed by a wildcard of the form
*dottedname or dotted * name or dotted name * gets as its result all nodes and their children
matching the regular expression created by the provided matching pattern.
■
A get command followed by a .* or a * gets as its result the set of attributes and their values
belonging to the current node to be matched.

Examples for the list --user admin-user --monitor Command
The list command provides information about the application components and subsystems
currently being monitored for the specified server instance name. Using this command, you can
see the monitorable components and subcomponents for a server instance. For a more
Example 1
asadmin> list --user admin-user --monitor server
The preceding command returns a list of application components and subsystems that have
monitoring enabled, for example:
server.resources
server.orb
server.jvm
server.jms-service
server.connector-service
server.applications
server.http-service
server.thread-pools
It is also possible to list applications that are currently monitored in the specified server
instance. This is useful when particular monitoring statistics are sought from an application
using the get command.
Example 2
asadmin> list --user admin-user --monitor server.applications
Returns:
server.applications.adminapp
server.applications.admingui
server.applications.myApp
Examples for the get --user admin-user --monitor Command
This command retrieves the following monitored information:
■
All attribute(s) monitored within a component or subsystem
■
Specific attribute monitored within a component or subsystem

To Use the PetStore Example
The following example illustrates how the asadmin tool might be used for monitoring purposes.
A user wants to inspect the number of calls made to a method in the sample PetStore
application after it has been deployed onto the Enterprise Server. The instance onto which it has
been deployed is named server. A combination of the list and get commands are used to
access desired statistics on a method.

2
Start the Enterprise Server and the asadmin tool.
Set some useful environment variables to avoid entering them for every command:
asadmin> export AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=admin123
asadmin>export AS_ADMIN_HOST=localhost AS_ADMIN_PORT=4848

List monitorable components for instance server:
asadmin> list --user adminuser --monitor server*
Returns (output will be similar to):
server
server.applications

■
Administration (management and monitoring) of the Enterprise Server is based on JMX
Technology. This means that the managed components are represented as MBeans in the
MBeanServer running in the Enterprise Server's JVM.
Java SE 5 enhances management and monitoring of the JVM by including a Platform MBean
Server and by including MBeans to configure the JVM. Enterprise Server leverages these
enhancements and registers its MBeans with the Platform MBean Server. Thus a JMX
Connector Client gets a unified view of JVM MBeans as well as Enterprise Server MBeans.
Chapter 18 • Monitoring Components and Services
209
Using JConsole
To view all the MBeans, Enterprise Server provides a configuration of the Standard JMX
Connector Server called System JMX Connector Server. As part of Enterprise Server startup, an
instance of this JMX Connector Server is started. Any compliant JMX connector client can
connect to the server using this Connector Server.
Java SE also provides tools to connect to an MBean Server and view MBeans registered with it.
JConsole is one such popular JMX Connector Client and is available as part of the standard Java
SE distribution. For more information on JConsole, see
When you configure JConsole with Enterprise Server, Enterprise Server becomes the JMX
Connector's server end and JConsole becomes the JMX Connector's preferred client end.
connection .
Securing JConsole to Application Server Connection
There are subtle differences in how to connect to Enterprise Server, or any JMX Connector
Server end, based on the transport layer security of the connection. If the server end is secure
(guarantees transport layer security), there is a little more configuration to be performed on the
client end.
■
By default, the developer profile of Enterprise Server is configured with a non-secure System
JMX Connector Server.
■
By default, cluster and enterprise profiles of Enterprise Server are configured with a secure
System JMX Connector Server.
■
The protocol used for communication is RMI/JRMP. If security is enabled for the JMX
Connector, the protocol used is RMI/JRMP over SSL.
Note – RMI over SSL does not provide additional checks to ensure that the client is talking to
the intended server. Thus, there is always a possibility, while using JConsole, that you are
sending the user name and password to a malicious host. It is completely up to the
administrator to make sure that security is not compromised.
When you install a developer profile domain on a machine such as appserver.sun.com, you
will see the following in the Domain Administration Server (DAS) domain.xml file:
<!- – The JSR 160 "system-jmx-connector" – –>
<jmx-connector accept-all="false" address="0.0.0.0"

Prerequisites for Connecting JConsole to Application
Server
The JConsole setup has two parts: a server end and a client end. For this example, the Enterprise
Server domain is installed on a machine called appserver.sun.com, which is a powerful Solaris
server. This is the server end.
The client end also has an installation of Enterprise Server. Let us assume that the client end is a
Windows machine with Java SE 6.0 and Enterprise Server installed.
Note – The Enterprise Server installation is needed on the client end only when your Enterprise
Server domain has security enabled on the remote machine (the default for cluster and
enterprise profiles). If you just want to administer an Enterprise Server developer profile
domain on the Solaris machine above, you do not need the Enterprise Server installation on this
client machine.
If the server and client ends are on the same machine, you can use localhost to specify the host
name.

In the Connect to Agent tab of JConsole, enter user name, password, host name and port (8686,
by default).
The user name refers to the administration user name and password refers to the
administration password of the domain.

Connecting JConsole Securely to Application Server
This procedure describes how to connect JConsole to Enterprise Server with security enabled
on the JMX Connector. By default, security is enabled on Enterprise Server cluster or enterprise
profiles. Use this procedure if you have security enabled on the developer profile's JMX
Connector.
1
Install Enterprise Server on the client machine (where JConsole is installed).
The only reason you need this is to let JConsole know where the server certificate of the Domain
Administration Server that you trust is located. To obtain that certificate, invoke at least one
remote asadmin command and to do that, you need the local installation of Enterprise Server.
2
3
Start the Enterprise Server on appserver.sun.com.
Since this is a cluster or enterprise domain, the system JMX Connector server is secure. To
enable security on the developer profile JMX Connector, see the Admin Console online help.
From the local Enterprise Server installation, run install-dir\bin\asadmin list --user admin
--secure=true --host appserver.sun.com --port 4848 (where 4848 is the server's
administration port).
Though asadmin list command is chosen for this example, you can run any remote asadmin
command. You are prompted to accept the certificate sent by the DAS of appserver.sun.com.
4
5
Press y to accept the certificate sent by the DAS on appserver.sun.com.
The server's certificate is stored in a file called .asadmintruststore in your home directory on
the client machine.
Note – This step is not required if your server machine and client machine is the same. That is, if
you are running JConsole also on appserver.sun.com.
Let JConsole know the trust store location by using the following JConsole command:
JDK-dir\bin\jconsole.exe -J-Djavax.net.ssl.trustStore="C:\Documents and
Settings\user\.asadmintruststore"

Configuring Management Rules
This section contains information about setting administration policies to automate routine
administration tasks, configure self-tuning of the application server for diverse runtime
conditions and improve availability by preventing failures. This section also contains
information on the self-management templates, which are predefined management rules that
you can customize.
This section contains the following topics:

About Management Rules
Management rules enable you to automate routine administration tasks, configure self-tuning
of the application server for diverse runtime condition and improve availability by preventing
failures. A management rule contains an action to be taken when a specified event occurs or a
set threshold is reached. You can set management rules that can automatically take corrective
action, based on events that you specify.
A management rule consists of two parts — event and action:
■
An event uses the JMX notification mechanism to trigger a predefined action.
■
An action is triggered when an associated event occurs. An action is an MBean which is a
notification listener which implements javax.management.NotificationListener.
For example, an event could be a SEVERE message logged by the EJB logger, and an action
could be alerting an administrator with the log message contents. When the event happens,
event data is passed as part of userData part of the javax.management.Notification.
The action specified in your rule has to be implemented as a custom MBean. Therefore, before
configuring a management rule, you should deploy a custom MBean designed to receive event
215
Configuring Management Rules
notifications and take appropriate action. For details on developing a custom MBean and
The Enterprise Server provides some useful events, which you can further extend by writing
custom MBeans to emit notifications. Each event can be further customized by changing its
properties.
The following event types are available:
■
Monitor events: Monitors an attribute of an MBean. Monitor events have similar
capabilities to javax.management.monitor package capabilities. In addition to monitoring
simple attributes, as Java SE 5 javax.management.monitor does, monitor events also
support monitoring complex attributes.
■
Notification events: Notifies of events from a custom MBean. Use these events to write
custom events and thus extend the event dictionary. Any MBeans which can emit a
notification can be an event.
■
System events:
■
Lifecycle: Events for sever startup, showdown, and termination.
■
Log: Events triggered when the specified logger writes a log entry. For example, you
could create a management rule to send an alert to an administrator when an EJB
container logger logs a SEVERE log entry.
■
Timer: Events triggered at the specified date and time, at the specified interval, and so on.
These events have capabilities similar to the javax.management.timer package.
■
Trace: Events triggered on Entry and Exit of HTTP/IIOP request methods, EJB methods,
and Web methods. For example, you can design a servlet filter used to log interactions
with a servlet as a management rule using Web method Entry and Exit events.
■
Cluster: Events triggered when a cluster or instance starts, stops, or fails. These events
use the Group Management System cluster monitoring.
Configuring Management Rules
To configure management rules in the Admin Console:
■
In the developer profile, go to Configuration → Management Rules
■
In the cluster and enterprise profiles, go to Configurations → Configuration →
Management Rules
Note – On this page, check All Rules Enabled to enable management rules globally. If
management rules are not enabled globally, none of the management rules are executed.
216
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Configuring Management Rules
In addition, to enable a individual management rule, you must enable the rule on this page by
clicking the box next to the rule and clicking Enable.
A rule's MBeans must also be enabled on a target. To enable MBeans, go to Custom MBeans →
MBean. On the Edit Custom MBean page, click the Target tab to access the Custom MBean
Targets page, where you can enable the MBeans on some or all of the targets.
For details, see the online help.
To create management rules from the command line, use the create-management-rule
command. To set properties of the management rules, use the get and set commands. To list
and delete management rules, use list-management-rules and delete-management-rule.

JavaVirtual Machine and Advanced Settings
The Java Virtual Machine (JVM) is an interpretive computing engine responsible for running
the byte codes in a compiled Java program. The JVM translates the Java byte codes into the
native instructions of the host machine. The Enterprise Server, being a Java process, requires a
JVM in order to run and support the Java applications running on it. JVM settings are part of an
application server configuration.
This chapter explains how to configure the Java Virtual Machine (JVMTM) and other advanced
settings. It contains the following sections:
■
■
Tuning the JVM Settings
As part of configuring the application server, you define settings that enhance the use of the Java
Virtual machine. To change the JVM configuration using the Admin Console, select
Application Server > JVM Settings tab and define the general JVM settings as follows:
■
Java Home: Enter the name of the installation directory of the Java software. The Enterprise
Server relies on the Java SE software.
Note – If you enter a nonexistent directory name or the installation directory name of an
unsupported version of the Java EE software, then the Enterprise Server will not start.
■
Javac Options: Enter the command-line options for the Java programming language
compiler. The Enterprise Server runs the compiler when EJB components are deployed.
■
Debug: To set up debugging with the JPDA (Java Platform Debugger Architecture), select
this Enabled checkbox.
JPDA is used by application developers.
219
Configuring Advanced Settings
■
■
■
Debug Options: Specify the JPDA options passed to the JVM when the debugging is
enabled.
RMI Compile Options: Enter the command-line options for the rmic compiler. The
Enterprise Server runs the rmic compiler when EJB components are deployed.
Bytecode Preprocessor: Enter a comma separated list of class names. Each class must
implement the com.sun.appserv.BytecodePreprocessor interface. The classes are called
in the order specified.
Tools such as profilers may require entries in the Bytecode Preprocessor field. Profilers
generate information used to analyze server performance.
Configuring Advanced Settings
To set the advanced application configuration using the Admin Console, select Application
Server > Advanced tab > Application Configuration tab and set the application configuration as
follows:
■
Reload: Select this checkbox to enable dynamic reloading of applications.
If dynamic reloading is enabled (it is by default), you do not have to redeploy an application
or module when you change its code or deployment descriptors. All you have to do is copy
the changed JSP or class files into the deployment directory for the application or module.
The server checks for changes periodically and redeploys the application, automatically and
dynamically, with the changes. This is useful in a development environment, because it
allows code changes to be tested quickly. In a production environment, however, dynamic
reloading might degrade performance. In addition, whenever a reload is done, the sessions
at that transit time become invalid. The client must restart the session.
■
Reload Poll Interval: Define the interval at which applications and modules are checked for
code changes and dynamically reloaded. The default is 2.
■
Admin Session Timeout: Specify the number of minutes of inactivity after which the admin
session times out.
In addition, define the deploy settings as follows:
■
Auto Deploy: Select this checkbox to enable automatic deployment of applications.
Autodeployment involves copying an application or module file (JAR, WAR, RAR, or EAR)
into a special directory, where it is automatically deployed by the Application Server.
■
Auto Deploy Poll Interval: Define the interval at which applications and modules are
checked for code changes and dynamically reloaded. The default is 2.
■
Verifier: Check the Verifier Enabled box to verify your deployment descriptor files. This is
optional.
■
Precompile: Check the Precompile Enabled box to precompile any JSP files.

Automatically Restarting a Domain or Node
Agent
If your domain or node agent is stopped unexpectedly (for example, if you need to restart your
machine), you can configure your system to automatically restart the domain or node agent.
This Appendix contains the following topics:
■
■
■
■
Restarting Automatically on Solaris 10
Solaris 10 users can use the command asadmin create-service to create a service that restarts
a node agent or Domain Administration Server (DAS). The service created uses the Solaris
Service Management Facility (SMF).
The process that a service starts depends on whether the service is to restart a DAS or a node
agent.
■
If the service is to restart a DAS, the process is asadmin start-domain.
■
If the service is to restart a node agent, the process is asadmin start-node-agent.
The service grants to the process the privileges of the user that runs the process. When you use
the command asadmin create-service to create an SMF service, the default user is the
superuser. If you require a different user to run the process, specify the user in
method_credential.
If your process is to bind to a privileged port of the Solaris OS, the process requires the
net_privaddr privilege. The privileged ports of the Solaris OS have a port numbers less than
1024.
221
Restarting Automatically on Solaris 10
To determine if a user has the net_privaddr privilege, log in as that user and type the command
ppriv -l | grep net_privaddr.
To run the asadmin create-service command, you must have solaris.smf.* authorization.
See the useradd and usermod man pages to find out how to set the authorizations. You must
also have write permission in the directory tree:
/var/svc/manifest/application/SUNWappserver. Usually, the superuser has both these
permissions. Additionally, the Solaris 10 administration commands such as svccfg, svcs, and
auths must be available in the PATH. For complete information on running this command, see
The syntax is as follows:
asadmin create-service [--name service-name] [--type das|node-agent]
--passwordfile password-file [--serviceproperties serviceproperties]
domain-or-node-agent-configuration-directory
For example, to create a service called domain1 for domain1:
1. Run the following:
asadmin create-service --type das --passwordfile password.txt
/appserver/domains/domain1
This creates a service to restart the domain domain1 automatically. In the background, the
command creates a manifest file from a template, validates the file, and imports it as a
service.
Note – If a particular Enterprise Server domain should not have default user privileges,
modify the service's manifest and reimport the service. To determine a user's privileges, log
in as that user and type the command ppriv -l.
2. Once the service is created, enable it using the svacdm enable command:
svacdm enable /appserver/domains/domain1
3. Once enabled, if the domain goes down, SMF restarts it.
As you administer your service, the following Solaris commands are useful:
■
auths
smf_security
svcadm
■
■
■
svccfg
rbac
■
■
useradd
usermod
■
For more information on these commands, see the command manpages.

Restarting Automatically on the MicrosoftWindows Platform
Restarting Automatically Using inittab on Solaris 9 and Linux
Platforms
To restart your domain on the Solaris 9 or Linux platform, add a line of text to the
/etc/inittab file.
If you use /etc/rc.local, or your system’s equivalent, place a line in /etc/rc.local that calls
the desired asadmin command.
For example, to restart domain1 for an Enterprise Server installed in the opt/SUNWappserver
directory, using a password file called password.txt:
das:3:respawn:/opt/SUNWappserver/bin/asadmin start-domain --user admin
--passwordfile /opt/SUNWappserver/password.txt domain1
Put the text on one line. The first three letters are a unique designator for the process and can be
altered.
To restart a node agent, the syntax is similar. For example, to restart agent1 for an Enterprise
Server installed in the opt/SUNWappserver directory, using a password file called
password.txt:
das:3:respawn:/opt/SUNWappserver/bin/asadmin start-node-agent --user admin
--passwordfile /opt/SUNWappserver/password.txt agent1
Restarting Automatically on the MicrosoftWindows Platform
To restart automatically on Microsoft Windows, create a Windows Service and prevent the
service from shutting down when a user logs out.
Creating aWindows Service
Use the appservService.exe and appserverAgentService.exe executable files shipped with
the Sun GlassFish Enterprise Server in conjunction with the Service Control command
(sc.exe) provided by Microsoft.
The sc.exe command comes with Windows XP and is in the system32 subdirectory of the
Windows installation directory (usually either C:\windows\system32 or C:\winnt\system32).
As of this writing, the Windows 2000 sc.exe is available for download at
Use appservService.exe and appservAgentService.exe as follows:
Appendix A • Automatically Restarting a Domain or Node Agent
223
Restarting Automatically on the MicrosoftWindows Platform
C:\winnt\system32\sc.exe create service-name binPath= \"fully-qualified-path-to-appservService.exe
\"fully-qualified-path-to-asadmin.bat start-command\"
\"fully-qualified-path-to-asadmin.bat stop-command\""
start= auto DisplayName= "display-name"
Note – There is no space between binpath and the equals sign (=). There must be a space after
the equals sign and before the path.
For example, to create a service called SunJavaSystemAppServer DOMAIN1 that starts and stops
the domain domain1, using a password file C:\Sun\AppServer\password.txt:
C:\windows\system32\sc.exe create domain1 binPath=
"C:\Sun\AppServer\lib\appservService.exe \"C:\Sun\AppServer\bin\asadmin.bat
start-domain --user admin --passwordfile C:\Sun\AppServer\password.txt domain1\"
\"C:\Sun\AppServer\bin\asadmin.bat stop-domain domain1\"" start= auto
DisplayName= "SunJavaSystemAppServer DOMAIN1"
To create a service that starts and stops the node agent agent1:
C:\windows\system32\sc.exe create agent1 binPath=
"C:\Sun\AppServer\lib\appservAgentService.exe \"C:\Sun\AppServer\bin\asadmin.bat
start-node-agent --user admin --passwordfile C:\Sun\AppServer\password.txt agent1\"
\"C:\Sun\AppServer\bin\asadmin.bat stop-node-agent agent1\"" start= auto
DisplayName= "SunJavaSystemAppServer AGENT1"
Note – The start and stop commands entered as part of the binPath= parameter must have the
correct syntax. To test, run the commands from the command prompt. If the commands do not
properly start or stop the domain or node agent, the service does not work correctly.
Note – Don’t use a mixture of asadmin start and stop commands and service start and stops.
Mixing the two can cause the server status to be out of sync. For example, the service might not
show that the component has started even though the component is not running. To avoid this
situation, always use the sc.exe command to start and stop the component when using
services.
If your sc.exe create command did not properly create the service, delete the service and try
again. To delete the service, use the sc.exe delete "service-name" command.

Security for Automatic Restarts
Preventing the Service From Shutting DownWhen a
User Logs Out
By default, the Java VM catches signals from Windows that indicate that the operating system is
shutting down, or that a user is logging out, and shuts itself down cleanly. This behavior causes
the Enterprise Server service to shut down when a user logs out of Windows. To prevent the
To set the -Xrs Java VM option, add the following line to the section of the
as-install\domains\domain-name\config\domain.xml file that defines Java VM options:
<jvm-options>-Xrs</jvm-options>
If the Enterprise Server service is running, stop and restart the service for your changes to
become effective.
Note – In some Windows 2003 Server installations, adding the -Xrs option to the domain.xml
file fails to prevent the service from shutting down. In this situation, add the option to the
as-install\lib\processLauncher.xml file as follows:
<process name="as-service-name">
...
<sysproperty key="-Xrs"/>
...
Security for Automatic Restarts
If you are using the cluster or enterprise profile, the administration passworda and master
password are required when automatically restarting Enterprise Server. If you are using the
Developer Profile, no
Handle the password and master password requirements for cluster and enterprise profiles in
one of the following ways:
■
On Microsoft Windows, configure the service to ask the user for the password.
1. In the Services Control Panel, double-click the service you created.
2. In the Properties window, click the Log On tab.
3. Check “Allow service to interact with desktop” to prompt for the required passwords
when starting the component.
You have to log in to see the prompts, and entries are not echoed back as you type them.
This method is the most secure way to use the services option, but user interaction is
required before the service becomes available.
Appendix A • Automatically Restarting a Domain or Node Agent
225
Security for Automatic Restarts
If the “interact with desktop” option is not set, the service stays in a “start-pending” state
and appears to hang. Kill the service process to recover from this state.
■
On Windows or UNIX, create a domain using the --savemasterpassword=true option and
create a password file to store the admin password. When starting the component, use the
--passwordfile option to point to the file that contains the password.
For example:
1. Create domain with a saved master password. In this syntax, you are prompted for the
administration password and master password:
asadmin create-domain --adminport 4848 --adminuser admin
--savemasterpassword=true --instanceport 8080 domain1
2. On Windows, create a service using a password file to populate the admin password:
C:\windows\system32\sc.exe create domain1 binPath=
"C:\Sun\AppServer\lib\appservService.exe \"C:\Sun\AppServer\bin\asadmin.bat
start-domain --user admin
--passwordfile C:\Sun\AppServer\password.txt domain1\"
\"C:\Sun\AppServer\bin\asadmin.bat stop-domain domain1\"" start= auto
DisplayName= "SunJavaSystemAppServer DOMAIN1"
The path to the password file password.txt is C:\Sun\AppServer\password.txt. It
contains the password in the following format
AS_ADMIN_password=password
For example, for a password adminadmin:
AS_ADMIN_password=adminadmin
3. On UNIX, use the --passwordfile option in the line you add to the inittab file:
das:3:respawn:/opt/SUNWappserver/bin/asadmin start-domain --user admin
--passwordfile /opt/SUNWappserver/password.txt domain1
The path to the password file password.txt is /opt/SUNWappserver/password.txt. It
contains the password in the following format
AS_ADMIN_password=password
For example, for a password adminadmin:
AS_ADMIN_password=adminadmin

Dotted Name Attributes for domain.xml
This appendix describes the dotted name attributes that can be used to address the MBean and

Top Level Elements
The following conditions must be adhered to for all top level elements in the domain.xml file:
■
Each server, configuration, cluster, or node agent must have a unique name.
■
Servers, configurations, clusters, or node agents cannot be named domain.
■
Server instances cannot be named agent.

Two levels of aliasing are available:
1. The first level of alias allows access to attributes of server instances or clusters without going
through the domain.servers or domain.clusters prefix. So, for example, a dotted name of
the form server1 maps to the dotted name domain.servers.server1 (where server1 is a
server instance).
2. The second level of alias is used to refer to configurations, applications, and resources of a
cluster or a standalone server instance (target).
The following table identifies dotted names beginning with the server name, or cluster name,
that are aliased to top level names under the domain:

The asadmin Utility

and applications.

The asadmin Utility
The asadmin Utility
Use the asadmin utility to perform any administrative tasks for the Application Server. You can
use this asadmin utility in place of using the Administrator interface.
The asadmin utility invokes subcommands that identify the operation or task you wish to
perform. Subcommands are case-sensitive. Short option arguments have a single dash (-); while
long option arguments have two dashes (--). Options control how the utility performs a
subcommand. Options are also case-sensitive. Most options require argument values except
boolean options which toggle to switch a feature ON or OFF. Operands appear after the
argument values, and are set off by a space, a tab, or double dashes (--). The asadmin utility
treats anything that comes after the options and their values as an operand.
asadmin can be used in command shell invocation or multi command mode (known as
multimode). In command shell invocation you invoke the asadmin utility from your command
shell. asadmin executes the command, then exits. In multiple command mode, you invoke
asadmin once, it then accepts multiple commands until you exit asadmin and return to the
normal command shell invocation. Environment variables set while in multiple command
mode are used for all subsequent commands until you exit multimode. You may provide
commands by passing a previously prepared list of commands from a file or standard input
(pipe). Additionally, you can invoke multimode from within a multimode session; once you exit
the second multimode environment, you return to your original multimode environment.
You can also run the asadmin utility in interactive or non-interactive options. By default, the
interactive option is enabled. It prompts you for the required arguments. You can use the
interactive option in command shell invocation under all circumstances. You can use the
interactive option in multimode when you run one subcommand at a time from the command
prompt; and when you run in multimode from a file. Subcommands in multimode, when piped
from an input stream, and subcommands invoked from another program, cannot run in the
interactive option.
Local subcommands can be executed without the presence of an administration server.
However, it is required that the user be logged into the machine hosting the domain in order to
execute the subcommand and have access (permissions) for the installation and domain
directories. Remote subcommands are always executed by connecting to an administration
server and executing the subcommand there. A running administration server is required. All
remote subcommands require the following options:
■
-u --user authorized domain application server administrative username.
■
--passwordfile the file containing the domain application server password in the
following form: AS_ADMIN_PASSWORD=password. Where password is the actual administrator
password.
■
-H --host machine name where the domain application server is running.
■
-p --port port number of the domain application server listening for administration

For subcommands that can be executed locally or remotely, if any one of the--host, --port,
--user, and --passwordfile options are set, either in the environment or in the command
line, the subcommand will run in remote mode. Additionally, for subcommands that can be
executed locally or remotely, if the --local option is set to true, the subcommand will run
locally. Also, if none of the local options are set, either on the command line or in the
environment, the subcommand is executed locally by default. Setting the --local option to
true overrides the local --host, --port, --user, and --passwordfile settings, even if specified.
The subcommand will run in local mode.
Subcommands that can be executed locally accept the --domain option to specify the domain of
interest which assumes the domain as the default domain if there is only one. If there is more
than one domain, the --domain option is a required option. For subcommands that can be run
locally or remotely, when run remotely with the--host, --port, --user, and --passwordfile
options specified, the --domain option is ignored. The --domain option is ignored if the
subcommand will be run in remote mode. Note that there is one administration instance per
domain, so on a single machine with multiple domains, local execution must specify the
domain, and remote execution must specify the --host, --port, --user, and --passwordfile
options for the administration instance for that domain.
For security purposes, you can set the password for a subcommand from a file instead of
entering the password at the command line. The --passwordfile option takes the file
containing the passwords. The valid contents for the file are:
EXAMPLE C–1 Passwordfilecontents
AS_ADMIN_PASSWORD=value
AS_ADMIN_ADMINPASSWORD=value
AS_ADMIN_USERPASSWORD=value
AS_ADMIN_MASTERPASSWORD=value
If AS_ADMIN_PASSWORD has been exported to the global environment, specifying the
--passwordfile option will produce a warning about using the --password option. Unset
AS_ADMIN_PASSWORD to prevent this from happening. The master password is not propagated
on the command line or an environment variable, but can be specified in the passwordfile.
Appendix C • The asadmin Utility
233
Common Options for Remote Commands
To use the --secure option, you must use the set command to enable the security --enabled
flag in the admin http-listener in the domain.xml. When you use the asadmin
subcommands to create and/or delete, you must restart the server for the newly created
command to take affect. Use the start-domain command to restart the server.
To access the manpages for the Application Server command-line interface subcommands on
the Solaris platform, add $AS_INSTALL/man to your MANPATH environment variable.
You can obtain overall usage information for any of the asadmin utility subcommands by
invoking the --help option. If you specify a subcommand, the usage information for that
subcommand is displayed. Using the --helpoption without a subcommand displays a listing of
all the available subcommands.
Common Options for Remote Commands
All the remote commands require the following common options:
TABLE C–1 Remote Commands Required Options
Option
Definition
--host
The machine name where the domain administration server is running. The default
value is localhost.
--port
--user
The HTTP/S port for administration. This is the port to which you should point your
browser in order to manage the domain. For example, http://localhost:4848. The
default port number for Platform Edition is 4848.
The authorized domain administration server administrative username. If you have
authenticated to a domain using the asadmin login command, then you need not
specify the --user option on subsequent operations to this particular domain.
234
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
The Multimode Command
TABLE C–1 Remote Commands Required Options
(Continued)
Option
Definition
--passwordfile
The --passwordfile option specifies the name of a file containing the password
entries in a specific format. The entry for the password must have the AS_ADMIN_
prefix followed by the password name in uppercase letters.
For example, to specify the domain administration server password, use an entry with
the following format: AS_ADMIN_PASSWORD=password, where password is the actual
administrator password. Other passwords that can be specified include
AS_ADMIN_MAPPEDPASSWORD, AS_ADMIN_USERPASSWORD, and
AS_ADMIN_ALIASPASSWORD.
All remote commands must specify the admin password to authenticate to the
domain administration server, either through--passwordfile or asadmin login, or
interactively on the command prompt. The asadmin login command can be used
only to specify the admin password. For other passwords, that must be specified for
remote commands, use the --passwordfile or enter them at the command prompt.
If you have authenticated to a domain using the asadmin login command, then you
need not specify the admin password through the --passwordfile option on
subsequent operations to this particular domain. However, this is applicable only to
AS_ADMIN_PASSWORD option. You will still need to provide the other passwords, for
example, AS_ADMIN_USERPASSWORD, as and when required by individual commands,
such as update-file-user.
For security reasons, passwords specified as an environment variable will not be read
by asadmin.
--secure
If set to true, uses SSL/TLS to communicate with the domain administration server.
If set to true (default), only the required password options are prompted.
--interactive
--terse
Indicates that any output data must be very concise, typically avoiding
human-friendly sentences and favoring well-formatted data for consumption by a
script. Default is false.
--echo
--help
Setting to true will echo the command line statement on the standard output. Default
is false.
Displays the help text for the command.
The Multimode Command
Use the multimode command to process the asadmin commands. The command-line interface
will prompt you for a command, execute that command, display the results of the command,
and then prompt you for the next command. Additionally, all the asadmin option names set in
this mode are used for all the subsequent commands. You can set your environment and run
commands until you exit multimode by typing “exit” or “quit.” You can also provide commands
by passing a previously prepared list of commands from a file or standard input (pipe). You can
Appendix C • The asadmin Utility
235
The Get, Set, and List Commands
invokemultimode from within a multimodesession; once you exit the second multimode
environment, you return to your original multimode environment.
The Get, Set, and List Commands
The asadmin get, set and list commands work in tandem to provide a navigation
mechanism for the Application Server's abstract hierarchy. There are two hierarchies:
configuration and monitoring and these commands operate on both. The list command
provides the fully qualified dotted names of the management components that have read-only
or modifiable attributes.
The configurationhierarchy provides attributes that are modifiable; whereas the attributes of
management components from monitoring hierarchy are purely read-only. The
configuration hierarchy is loosely based on the domain's schema document; whereas the
monitoringhierarchy is a little different.
Use the list command to reach a particular management component in the desired hierarchy.
Then, invoke the getand set commands to get the names and values or set the values of the
attributes of the management component at hand. Use the wildcard (*) option to fetch all
matches in a given fully qualified dotted name. See the examples for further clarification of the
possible navigation of the hierarchies and management components.
An application server dotted name uses the “.” (period) as a delimiter to separate the parts of a
complete name. This is similar to how the “/” character is used to delimit the levels in the
absolute path name of a file in the UNIX file system. The following rules apply while forming
the dotted names accepted by the get, set, and list commands. Note that a specific command
has some additional semantics applied.
■
A . (period) always separates two sequential parts of the name.
■
A part of the name usually identifies an application server subsystem and/or its specific
instance. For example: web-container, log-service, thread-pool-1, etc.
■
If any part of the name itself contains a . (period), then it must be escaped with a leading
\(backslash) so that the “.” does not act like a delimiter.
■
An * (asterisk) can be used anywhere in the dotted name and it acts like the wildcard
character in regular expressions. Additionally, an * can collapse all the parts of the dotted
name. Long dotted name like "<classname>this.is.really.long.hierarchy
</classname>" can be abbreviated to "<classname>th*.hierarchy</classname>."But
note that the . always delimits the parts of the name.
■
The top level switch for any dotted name is --monitor or -m that is separately specified on a
given command line. The presence or lack of this switch implies the selection of one of the
two hierarchies for application server management: monitoring and configuration.
■
If you happen to know the exact complete dotted name without any wildcard character, then
list and get/set have a little difference in their semantics:
236
Sun GlassFish Enterprise Server 2.1 Administration Guide • December 2008
Server Lifecycle Commands
■
The list command treats this complete dotted name as the complete name of a parent
node in the abstract hierarchy. Upon providing this name to list command, it simply
returns the names of the immediate children at that level. For example,list
server.applications.web-module will list all the web modules deployed to the domain
or the default server.
■
The get and set commands treat this complete dotted name as the fully qualified name
of the attribute of a node (whose dotted name itself is the name that you get when you
remove the last part of this dotted name) and it gets/sets the value of that attribute. This
is true if such an attribute exists. You will never start with this case because in order to
find out the names of attributes of a particular node in the hierarchy, you must use the
wildcard character *. For example,
server.applications.web-module.JSPWiki.context-root will return the
context-root of the web-application deployed to the domain or default server.
The list command is the progenitor of navigational capabilities of these three commands. If
you want to set or get attributes of a particular application server subsystem, you must know
its dotted name. The list command is the one which can guide you to find the dotted name of
that subsystem. For example, to find out the modified date (attribute) of a particular file in a
large file system that starts with /. First you must find out the location of that file in the file
system, and then look at its attributes. Therefore, two of the first commands to understand the
hierarchies in appserver are: * list "*" and <command>* list * --monitor. Consult the get
set or list commands manpages to identify the sorted output of these commands.
Server Lifecycle Commands
The server lifecycle commands are commands that create, delete, or start, stop a domain, or an
instance.
TABLE C–2 Server LifecycleCommands
Command
Definition
create-domain
Creates the configuration of a domain. A domain is an administrative
namespace. Every domain has a configuration, which is stored in a set of files.
Any number of domains each of which has a distinct administrative identity
can be created in a given installation of application server. A domain can exist
independent of other domains. Any user who has access to the asadmin script
on a given system can create a domain and store its configuration in a folder of
choice. By default, the domain configuration is created in the
install_dir/domains directory. You can override this location to store the
configuration elsewhere.
delete-domain
Deletes the named domain. The domain must already exist and must be
stopped.

Command
Definition
start-domain
Starts a domain. If the domain directory is not specified, the domain in the
default install_dir/domains directory is started. If there are two or more
domains, the domain_name operand must be specified.
stop-domain
Stops the Domain Administration Server of the specified domain.
Restores files under the domain from a backup directory.
restore-domain
list-domains
Lists the domain. If the domain directory is not specified, the domain in the
default install_dir/domains directory is listed. If there is more than one
domain, the domain_name operand must be specified.
backup-domain
login
Backs up files under the named domain.
Lets you log in to a domain. If various application server domains are created
on various machines (locally), asadmin invocation from any of these machines
can manage the domains located elsewhere (remotely). This comes in handy
especially when a particular machine is chosen as an administration client and
it manages multiple domains and servers. asadmin commands that are used to
manage domains located elsewhere are called remote commands. The asadmin
login command eases the administration of such remote domains. The login
command runs only in the interactive mode. It prompts you for the admin user
name and password. On successful login, the file .asadminpass will be created
in the user's home directory. This is the same file that is modified during the
create-domain command while using the --savelogin option. The domain
must be running for this command to run.
create-instance
delete-instance
Creates a new server instance residing on a local or remote machine.
Deletes the server instance. This command can be run remotely or locally. The
user authenticates using the password identified for the administration server.
Additionally, the instance must already exist within the domain served by the
administration server. Use this command with discretion since it is destructive
and cannot be undone.

command to map the caller identity of the application (principal or
user group) to a suitable enterprise information system (EIS)
principal in container-managed transaction-based scenarios. One or
more named security maps may be associated with a connector
connection pool. The connector security map configuration supports
the use of the wild card asterisk (*) to indicate all users or all user
groups. For this command to succeed, you must have first created a
connector connection pool. The EIS is any system that holds the data
of an organization. It can be a mainframe, a messaging system, a
database system, or an application.
delete-connector-security-map
update-connector-security-map
list-connector-security-map
Deletes a security map for the specified connector connection pool.
Modifies a security map for the specified connector connection pool.
Lists the security maps belonging to the specified connector
connection pool.
create-message-security-provider Enables administrators to create a provider-config sub-element for
the given message layer (message-security-config element of
domain.xml, the file that specifies parameters and properties to the
Application Server).

Password Commands
TABLE C–20 Security Commands
Command
(Continued)
Definition
delete-message-security-provide Enables administrators to delete a provider-config sub-element for
the given message layer (message-security-config element of
domain.xml, the file that specifies parameters and properties to the
Application Server).
list-message-security-providers Enables administrators to list all security message providers
(provider-config sub-elements) for the given message layer
(message-security-config element of domain.xml).
Password Commands
The password commands allow you to manage passwords and ensure security for the
application server.
TABLE C–21 PasswordCommands
Command
Definition
create-password-alias
Creates an alias for a password and stores it in domain.xml. An alias is a token
of the form ${ALIAS=password-alias-password}. The password
corresponding to the alias name is stored in an encrypted form. This
command takes both a secure interactive form (in which the user is prompted
for all information) and a more script-friendly form, in which the password is
propagated on the command line.
delete-password-alias
update-password-alias
list-password-aliases
change-admin-password
Deletes a password alias.
Updates the password alias IDs in the named target.
Lists all password aliases.
This remote command modifies the admin password. This command is
interactive in that the user is prompted for the old and new admin password
(with confirmation).
change-master-password
This local command is used to modify the master password. This command is
interactive in that the user is prompted for the old and new master password.
This command will not work unless the server is stopped.

TABLE C–22 VerifyCommand
Command
Definition
verify-domain-xml
Verifies the content of the domain.xml file.
Custom MBean Commands
The MBean commands allow you to manage and register custom MBeans. The commands are
supported in remote mode only.
TABLE C–23 Custom MBean Commands
Command
Definition
create-mbean
Creates and registers a custom MBean. If the target MBeanServer is not
running, the MBean is not registered.
delete-mbean
list-mbeans
Deletes a custom MBean. Ensure that the target MBeanServer is running.
Lists the custom mbeans for the specified target.
Service Command
The service command allows you to configure the starting of the Domain Administration
Server (DAS).
TABLE C–24 ServiceCommand
Command
Definition
create-service
Configures the starting of a DAS on an unattended boot. On Solaris 10, this
command uses the Service Management Facility (SMF). This is a local
command and must be run as the OS-level user with superuser privileges. It is
available only for Solaris 10. When the service is created, the user has to start,
enable, disable, delete, or stop the service. The DAS must be stored on a folder
to which the super-user has access. The configuration cannot be stored on a
network file system. The service is created such that it is controlled by the
OS-level user, who owns the folder where the configuration of the DAS
resides. To run this command, you must have solaris.smf.* authorization.
