The goal of this book is to get you up and running J2EE 1.4 applications on JBoss 4.0 as quickly as possible. At the time of writing, the latest release is version 4.0.0. You should use this version or later with the examples. We will use Sun’s J2EE 1.4 tutorial examples (http://java.sun.com/j2ee/1.4/docs/tutorial/doc/) to illustrate the deployment and configuration of J2EE applications in JBoss. While the book is not intended to teach you J2EE, we will be covering the subject from quite a basic standpoint, so it will still be useful if you are new to J2EE. If you would like to use JBoss to run the standard Sun J2EE tutorials then this is the book for you. It should ideally be read in parallel with the tutorial texts.
