WebSphere JMS Provider Publish and Subscribe messaging support
 Technote (troubleshooting)
 
Problem(Abstract)
Does the internal WebSphere® JMS™ Provider provide Publish and Subscribe messaging support?
 
Resolving the problem
Yes.

In J2EE™ 1.3, the Java Messaging Service becomes an integral part of the J2EE platform.  In v5.0, WebSphere satisfies this requirement with the Internal WebSphere JMS Provider that is installed with WebSphere Application server.  This component provides embedded Point-to-Point and Publish and Subscribe support by introducing a new kind of WebSphere Application Server server, the JMS Server.

 Point-to-Point messaging employs a queue as the JMS destination. Each message in the queue is delivered only to a single consumer. Publish and Subscribe service employs a topic as the JMS destination.  Subscribers register their interest in a particular topic. Publishers create messages that are distributed to all of the subscribers.  Multiple subscribers can subscribe to this topic, and each subscribing client receives the message.

Each WebSphere Application Server Embedded Messaging JMS Server is responsible for managing a Queue Manager and a roker.  The broker is the provider of the Publish and Subscribe service.
