Sams Teach Yourself BEA WebLogic Server 7.0 in 21 Days

In today's lesson, you learned about the emergence of the Java Message Service (JMS). You studied concepts about point-to-point messaging and publisher-subscriber messaging. There was then a brief discussion of the JMS API. You read about the J2EE specifications to which the JMS server must conform and the JMS API architecture. You then learned about the individual components of a message object and a few important interfaces of the API used in creating queues and topics.

From there, you went on to look at the WebLogic JMS architecture, the special features in point-to-point and publisher-subscriber messaging, and the important API of WebLogic JMS architecture. You saw the WebLogic-specific features of JMS.

The life cycle of a JMS application was the next topic. You saw how to configure destinations on the WebLogic Server and then implemented the sample restaurant application using JMS functionality.

The last topic was message-driven beans. The important methods and the important points of message-driven beans were covered in this lesson. Sample code snippets for developing a message-driven bean and its deployment descriptors were shown.
