Course Description
The Java Message Service is a Java API for sending and receiving messages. The API has variants for both Java SE and Java EE, with additional features such as JTA (XA) transactions available for Java EE. This course will cover the use of the JMS API in Java EE applications. It will cover the JMS messaging styles, how to handle messages synchronously and asynchronously, and the use of queues and topics as well as using EJBs as messaging clients. Message-driven beans (MDBs) are intended as message consumers and this course will also cover how to create and use MDBs in Java EE applications.
