To configure the JMS Service and prepare JMS resources for use in applications deployed to the Enterprise Server, you must perform these tasks:
For more information about JMS administration tasks, see Chapter 4, Configuring Java Message Service Resources, in Sun GlassFish Enterprise Server v2.1.1 Administration Guide and the Sun GlassFish Message Queue 4.4 Administration Guide.
The JMS Service configuration is available to all inbound and outbound connections pertaining to the Enterprise Server cluster or instance. You can edit the JMS Service configuration in the following ways:
server.jms-service.init-timeout-in-seconds = 60 server.jms-service.type = EMBEDDED server.jms-service.start-args = server.jms-service.default-jms-host = default_JMS_host server.jms-service.reconnect-interval-in-seconds = 60 server.jms-service.reconnect-attempts = 3 server.jms-service.reconnect-enabled = true server.jms-service.addresslist-behavior = random server.jms-service.addresslist-iterations = 3 server.jms-service.mq-scheme = mq server.jms-service.mq-service = jms
You can also set these properties:
server.jms-service.property.instance-name = imqbroker server.jms-service.property.instance-name-suffix = server.jms-service.property.append-version = false server.jms-service.property.user-name = server.jms-service.property.password =
You can use the asadmin get command to list all the JMS service attributes and properties. For details, see the Sun GlassFish Enterprise Server v2.1.1 Reference Manual.
You can override the JMS Service configuration using JMS connection factory settings. For details, see Chapter 4, Configuring Java Message Service Resources, in Sun GlassFish Enterprise Server v2.1.1 Administration Guide.
The Enterprise Server instance must be restarted after configuration of the JMS Service.
A JMS host refers to a Sun GlassFish Message Queue broker. A default JMS host for the JMS service is provided, named default_JMS_host. This is the JMS host that the Enterprise Server uses for performing all Message Queue broker administrative operations, such as creating and deleting JMS destinations.
If you have created a multi-broker cluster in the Message Queue software, delete the default JMS host, then add the Message Queue cluster’s brokers as JMS hosts. In this case, the default JMS host becomes the first JMS host in the AddressList. For more information about the AddressList, see JMS Connection Features. You can also explicitly set the default JMS host; see Configuring the JMS Service.
When the Enterprise Server uses a Message Queue cluster, it executes Message Queue specific commands on the default JMS host. For example, when a physical destination is created for a Message Queue cluster of three brokers, the command to create the physical destination is executed on the default JMS host, but the physical destination is used by all three brokers in the cluster.
Use the asadmin create-jms-host command. For details, see the Sun GlassFish Enterprise Server v2.1.1 Reference Manual.
For machines having more than one host, use the Host field in the Admin Console or the -–mqhost option of create-jms-host to specify the address to which the broker binds.
You can use the asadmin jms-ping command to check whether a Sun GlassFish Message Queue instance is running. For details, see the Sun GlassFish Enterprise Server v2.1.1 Reference Manual.
Produced messages are delivered for routing and subsequent delivery to consumers using physical destinations in the JMS provider. A physical destination is identified and encapsulated by an administered object (a Topic or Queue destination resource) that an application component uses to specify the destination of messages it is producing and the source of messages it is consuming.
If a message-driven bean is deployed and the Queue physical destination it listens to doesn’t exist, the Enterprise Server automatically creates the physical destination and sets the value of the property maxNumActiveConsumers to -1 (see Load-Balanced Message Inflow). However, it is good practice to create the Queue physical destination beforehand.
You can create a JMS physical destination in the following ways:
Use the asadmin create-jmsdest command. This command acts on the default JMS host of its target. For details, see the Sun GlassFish Enterprise Server v2.1.1 Reference Manual.
To purge all messages currently queued at a physical destination, use the asadmin flush-jmsdest command. This deletes the messages before they reach any message consumers. For details, see the Sun GlassFish Enterprise Server v2.1.1 Reference Manual.
To create a destination resource, see Creating JMS Resources: Destinations and Connection Factories.
You can create two kinds of JMS resources in the Enterprise Server:
In either case, the steps for creating a JMS resource are the same. You can create a JMS resource in the following ways:
To create a JMS resource using the Admin Console, open the Resources component, then open the JMS Resources component. Click Connection Factories to create a connection factory, or click Destination Resources to create a queue or topic. For details, click the Help button in the Admin Console.
A JMS resource is a type of connector. To create a JMS resource using the command line, see Deploying and Configuring a Stand-Alone Connector Module.
All JMS resource properties that used to work with version 7 of the Enterprise Server are supported for backward compatibility.
