Day 15. Using the JMS API

Yesterday's session focused entirely on understanding transaction concepts and the use of the Java Transaction API (JTA) in applications deployed on WebLogic Server. You started the day studying the basic ACID properties of a transaction namely, atomicity, consistency, isolation, and durability and the life cycle of a transaction. Then you covered the concepts of transaction architecture and the Java transaction API. After this, yesterday's lesson covered the two possible ways to configure transactions in WebLogic Server: container-managed transactions (that is, the declarative method) and bean-managed transactions (that is, the programmatic method).

Today's lesson covers another technology supported by WebLogic Server, the Java Message Service (JMS) API. You will start the day by studying simple messaging concepts such as point-to-point and publish-subscribe protocols. Then you will study the different classes and interfaces in the JMS API. Finally, you will study how to configure a message queue connection factory in WebLogic Server and learn the concepts of the last type of EJB: the message-driven bean.
