What Is a Message-Driven Bean?
A message-driven bean is an enterprise bean that allows J2EE applications to process messages asynchronously. It normally acts as a JMS message listener, which is similar to an event listener except that it receives JMS messages instead of events. The messages can be sent by any J2EE component—an application client, another enterprise bean, or a Web component—or by a JMS application or system that does not use J2EE technology. Message-driven beans can process either JMS messages or other kinds of messages.
For a simple code sample, see Chapter 28. For more information about using message-driven beans, see Using the JMS API in a J2EE Application (page 1212) and Chapter 34.
