The JMQ Notification plug-in allows you to deliver notification messages using the Java Messaging Service (JMS) standard. You can now configure plug-ins to send notifications to two different messaging services:
Sun Java System Message Queue 3.6 or later, which implements the JMS standard
Event Notification Service
With Message Queue, you can produce topics to a message or a queue, or to both of these delivery methods. Message Queue also provides enhanced load balancing, scalability, and reliability. See Chapter 22, Configuring the JMQ Notification Plug-in to Produce Messages for Message Queue, in Sun Java System Messaging Server 6.3 Administration Guide.
