The primary focus of this book is the presentation of the standard JBoss 4.0 architecture components from both the perspective of their configuration and architecture. As a user of a standard JBoss distribution you will be given an understanding of how to configure the standard components. Note that this book is not an introduction to J2EE or how to use J2EE in applications. It focuses on the internal details of the JBoss server architecture and how our implementation of a given J2EE container can be configured and extended.

As a JBoss developer, you will be given a good understanding of the architecture and integration of the standard components to enable you to extend or replace the standard components for your infrastructure needs. We also show you how to obtain the JBoss source code, along with how to build and debug the JBoss server.
