Overview of this book

JBoss Application Server meets high standards of reliability, efficiency, and robustness, and is used to build powerful and secure Java EE applications. It supports the most important areas of Java Enterprise programming including EJB 3.1, Contexts and Dependency Injection, JAX-WS and JAX-RS web services, the security framework, and more. Getting started with JBoss application server development can be challenging; however, with the right approach and guidance, you can easily master it and this book promises that.Written in an easy-to-read style, this book will take you from the basics of JBoss AS—such as installing core components and plugins—to the skills that will make you a JBoss developer to be reckoned with, covering advanced topics such as developing applications with the JBoss messaging service, JBoss web services, clustered applications, and more.You will learn the necessary steps to install a suitable environment for developing enterprise applications on JBoss AS. You will also learn how to design Enterprise applications using Eclipse, JBoss plugins, and Maven to build and deploy your applications. Readers will learn how to enable distributed communication using JMS. Storing and retrieving objects will be made easier using the Java Persistence API. The core section of the book will take you into the programming arena with tested, real-world examples. The example programs have been carefully crafted to be easy to understand and useful as starting points for your applications. This practical guide will show you how to gain hands-on experience rapidly on Java EE development using JBoss AS with easy-to-understand and practical programming examples.

Chapter 7. Developing Applications with JBoss JMS Provider

Messaging is a method of communication between software components and applications. The Java Message Service (JMS) documented at http://java.sun.com/products/jms/docs.html is a Java API designed by Sun that allows applications to create, send, receive, and read messages.

Messaging differs from other standard protocols, such as Remote Method Invocation (RMI) or Hypertext Transfer Protocol (HTTP), in two ways. First, the conversation is mediated by a messaging server, so it's not a two-way conversation between peers. Second, the sender and the receiver need to know what message format and what destination to use. This is in contrast to tightly coupled technologies, such as Remote Method Invocation (RMI), which require an application to know a remote application's methods.

In this chapter, we will cover:

  • A brief introduction to message-oriented systems

  • The building blocks of the JBoss messaging subsystem

  • Setting up some proof of concept...
