Migrating from WebSphere Application Server Version 5 embedded messaging

This set of topics describes the migration of JMS applications from the embedded messaging in WebSphere Application Server Version 5 to the default messaging provider in WebSphere Application Server Version 6.

About this task

You can temporarily use Application Server Version 5 JMS resources with service integration in WebSphere Application Server Version 6, however you should ideally migrate all resources to Version 6 as soon as possible.

For general migration considerations, see General considerations for migrating from Version 5 embedded messaging.

When migrating a Version 5 node to Version 6, you do not have to modify your JMS applications; they can continue to use most of the existing Version 5 JMS deployment, installation, and configuration settings. However, when migrating a Version 5 message-driven bean (MDB) application, you must modify the configuration to provide a JMS activation specification, not a listener port (MDBs do not use listener ports), then redeploy or reinstall the MDB application.

Note: It is intended that WebSphere Application Server Version 5 will no longer support connections from application servers or J2EE application clients to the JMS server component of embedded messaging. When this happens, it will no longer be possible to define JMS resources for the Version 5 default messaging provider. It is also intended that WebSphere Application Server Version 5 will also no longer support connections from client applications executing in a Version 5 environment, or applications using Version 5 default messaging provider resources, to the messaging engines in WebSphere Application Server Version 6. When this happens, it will no longer be possible to define a WebSphere MQ client link property for messaging engines.
