The Java Message Service (JMS) API is a messaging standard that allows Java EE applications and components to create, send, receive, and read messages. It enables distributed communication that is loosely coupled, reliable, and asynchronous. The Sun Java System Message Queue (MQ), which implements JMS, is tightly integrated with Enterprise Server, enabling you to create components such as message-driven beans (MDBs).
MQ is integrated with Enterprise Server using a connector module, also known as a resource adapter, defined by the Java EE Connector Architecture Specification 1.5. Java EE components deployed to the Enterprise Server exchange JMS messages using the JMS provider integrated via the connector module. Creating a JMS resource in Enterprise Server creates a connector resource in the background. So, each JMS operation invokes the connector runtime and uses the MQ resource adapter in the background.
You can manage the Java Message Service through the Admin Console or the asadmin command-line utility.
