In this chapter, we covered an introduction to JMS and messaging systems in general. We talked about the two JMS messaging domains, namely the PTP messaging domain, in which a single listener processes a message, and the pub/sub messaging domain, in which all subscribed message listeners process the message.

Then, we covered how to create JMS resources such as message queues quickly and easily by taking advantage of the NetBeans JMS Resource wizard.

We also covered how to send JMS messages using JMS 2.0 included in Java EE 7, and we saw how NetBeans can generate most of the JMS boilerplate code.

Then, we turned our attention to developing code to receive and process JMS messages, specifically how to develop message-driven beans via the NetBeans Message-Driven Bean wizard.
