Summary

In this chapter, we learned that WebSphere provides a level of abstraction to messaging configuration by allowing resources to be referenced by JNDI. We deployed a message-enabled application which required a queue connection factory and queue destination which it used to send and receive messages. We configured two different implementations of JMS. One implementation used the internal Default Messaging Provider, which required a SIB to be created, and we covered how to create the QCF and queue destinations and bound the applications resource references to those configured in WebSphere.

We then covered how to install WebSphere MQ and learned how to create a queue manager and a queue. Then, in WebSphere, we created a QCF and queue destination using the WebSphere MQ provider and demonstrated how to to re-map our applications resource references to re-point the application to use MQ messaging subsystem as opposed to the internal messaging subsystem.
