Create a new listener port

Create a new listener port for the message listener service to define the association between a connection factory, a destination, and a deployed message-driven bean. This association enables the message-driven bean to retrieve messages from the associated destination.

To use message-driven beans with a messaging provider that does not have a JCA Version 1.5 or 1.6 resource adapter, we cannot use activation specifications and therefore configure beans against a listener port. There are also a few scenarios in which, although we could use activation specifications, we might still choose to use listener ports. For example, for compatibility with existing message-driven bean applications.

If we have existing message-driven beans that use the IBM MQ messaging provider (or a compliant third-party JMS provider) with listener ports, and instead we want to use EJB 3 message-driven beans with listener ports, these new beans can continue to use the same messaging provider.

A listener port defines the association between a connection factory, a destination, and a deployed message-driven bean. This association enables deployed message-driven beans associated with the port to retrieve messages from the destination. For more information, see Message-driven beans - listener port components.


Tasks

  1. Start the administrative console.

  2. In the navigation pane, click...

      Servers > Server Types > WebSphere application servers->server > [Communications] Messaging > Message listener service > [Additional Properties] Listener Ports > listener_port

    The Message listener port collection panel is displayed.

  3. Click New.

  4. Specify the following required properties:

    Name The name by which the listener port is known for administrative purposes.
    Connection factory JNDI name The JNDI name for the JMS connection factory to be used by the listener port; for example, jms/connFactory1.
    Destination JNDI name The JNDI name for the destination to be used by the listener port; for example, jms/destn1.

  5. Optional: Change other properties for the listener port, as required.

  6. Click OK.

  7. Save changes to the master configuration.

  8. To have the changed configuration take effect, stop then restart the application server.

If we set the initial state of a listener port to Started, the listener port is started automatically when a message-driven bean associated with that port is installed.
