I have found a very good explanation of JMS with an example.

That is a simple chat application with JMS queues are used to communicate messages between users and messages stay in the queue if the receiver is offline.

In this example implementation they have used

• XSD to generate domain classes.
• Eclipse EE as IDE.
• JBoss as web/application server.
• HTML/JavaScript/JQuery for UI.
• Servlet as controller.
• MySQL as DB.

The JBoss configuration step for queue is explained nicely Its available at http://coder2design.com/messaging-service/

Even the downloadable code is also available there.
