Jakarta Messaging

Jakarta Messaging provides a mechanism for Jakarta EE applications to send messages to each other. Jakarta Messaging applications do not communicate directly; instead, message producers send messages to a destination, and message consumers receive the message from the destination.

The message destination is a message queue when the point-to-point (PTP) messaging domain is used, or a message topic when the publish/subscribe (pub/sub) messaging domain is used.

In this chapter, we will cover the following topics:

• Working with message queues
• Working with message topics
