Managing message-driven beans

You can manage the Java™ EE Connector Architecture (JCA) Version 1.5-compliant message-driven beans that you deploy as message endpoints, and you can manage the message listener resources for non-JCA message-driven beans that you deploy against listener ports.

Before you begin

For WebSphere® Application Server Version 7 and later, listener ports are stabilized. For more information, read the article on stabilized features. You should plan to migrate your WebSphere MQ message-driven bean deployment configurations from using listener ports to using activation specifications. However, you should not begin this migration until you are sure the application does not have to work on application servers earlier than WebSphere Application Server Version 7. For example, if you have an application server cluster with some members at Version 6.1 and some at Version 7, you should not migrate applications on that cluster to use activation specifications until after you migrate all the application servers in the cluster to Version 7.

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

For more information about when to use listener ports rather than activation specifications, see Message-driven beans, activation specifications, and listener ports.

About this task

You can manage the following resources for message-driven beans:
  • JCA 1.5-compliant message-driven beans that you deploy as message endpoints, and the associated activation specifications.
  • The message listener service, listener ports, and listeners for non-JCA message-driven beans that you deploy against listener ports.
