Overview of the `simplemessage` Example

The simplemessage application has the following components:

SimpleMessageClient: An application client that sends several messages to a queue
SimpleMessageBean: A message-driven bean that asynchronously receives and processes the messages that are sent to the queue

Figure 25-1 illustrates the structure of this application. The application client sends messages to the queue, which was created administratively using the Administration Console. The JMS provider (in this case, the GlassFish Server) delivers the messages to the instances of the message-driven bean, which then processes the messages.

The source code for this application is in the tut-install/examples/ejb/simplemessage/ directory.
