Configure JMS system modules and add JMS resources

Before you begin

JMS system modules contains configuration JMS resources, such queues, topics, templates, and connections factories, and are defined by XML documents that conform to the weblogic-jmsmd.xsd schema. System modules configured through the Administration Console are stored in the config\jms subdirectory of the domain directory, and a reference to the module is added in the domain's configuration file as a JMSSystemResource element. This reference includes the path to the JMS module file and a list of target JMS servers, servers, and clusters on which the module is deployed.

System modules are globally available for targeting to servers and clusters configured in the domain, and therefore are available to all applications deployed on the same targets and to client applications.

Note: JMS configuration resources can also be managed as deployable application modules, either with a J2EE application as a packaged module, which is available only to the enclosing application, or as a stand-alone module that provides global access to the resources defined in that module. For more information about configuring JMS application modules, see Configuring JMS Application Modules for Deployment

To configure a JMS system module:

  1. Create a JMS system module to contain your JMS resources, such as queue and topic destinations, connection factories, quota, and JMS templates. See Configure JMS system modules.

    While creating a JMS system module, you can also add JMS resources to the module by selecting the Would you like to add resources? check box. The remaining steps explain how to create resources by using the Summary of Resources table on a JMS module's Configuration page.

  2. Before configuring any queue or topic resources in your module, you can optionally create other JMS resources in the module that can be referenced from within a queue or topic, such as quota settings, templates, and destination keys:
    • Quotas are used to control the allotment of system resources available to destinations. See Configure quotas for destinations.
    • Templates provide an efficient means of defining multiple JMS queues and topics with similar configuration settings. See Configure JMS templates.
    • Destination keys allow you to define the sort order of messages that arrive on a specific queue or topic. See Configure destination keys.
  3. Configure a topic in your JMS module. See Configure topics.
  4. Configure a queue in your JMS module. See Configure queues.
  5. If the default connection factories provided by WebLogic Server are not suitable for your application, create a new connection factory to enable your JMS clients to create JMS connections. See Configure connection factories.

    For more information on using the default connection factories, see Configuring and Managing WebLogic JMS.

  6. In a clustered environment, you can create a distributed destination, which is a set of queues or topics that are called under a single JNDI name so they appear to be a single, logical destination to a client. However, the members of the set are actually distributed across multiple servers within a cluster, with each destination member belonging to a separate JMS server.
  7. If you need to access a foreign JNDI provider, you can configure a Foreign Server, which represents a JNDI provider that is outside WebLogic server. It contains information that allows a local WebLogic Server instance to reach a remote JNDI provider, thereby allowing for a number of foreign connection factory and destination objects to be defined on one JNDI directory. See Configure foreign servers.
  8. If you need to reliably send messages to remote destinations outside the local server instance, the JMS SAF (store-and-forward) feature builds on the WebLogic SAF service to provide highly-available JMS message production. For example, a JMS message producer connected to a local server instance can reliably forward messages to a remote JMS destination, even though that remote destination may be temporarily unavailable when the message was sent. See Configure JMS SAF.
