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.

JBoss AS 7 clustering


JBoss AS comes out of the box with clustering support. There is no all-in-one library that deals with clustering, but rather a set of libraries that cover different kinds of aspects.

The following diagram shows the basic clustering architecture adopted by JBoss AS 7:

The backbone of JBoss clustering is the JGroups library, which provides communication between members of the cluster using a multicast transmission.

Note

Multicast is a protocol where data is transmitted simultaneously to a group of hosts that have joined the appropriate multicast group. You can think about multicast as a radio or television streaming, where only those tuned to a particular frequency receive the streaming.

The next building block is Infinispan , which handles the consistency of your application across the cluster by means of a replicated and transactional JSR-107-compatible cache.

Note

JSR-107 specifies the API and semantics for temporary, in-memory caching of Java objects, including object...
