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 GlassFish Server automatically creates the physical destination. 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 Oracle GlassFish Server 3.0.1 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 Oracle GlassFish Server 3.0.1 Reference Manual.
To create a destination resource, see Creating JMS Resources: Destinations and Connection Factories.
