Good overall book on how to deploy J2EE apps to JBoss. It follows a step-by-step approach (which at times might be annoying, but it does the job). Not much theory, though. If you want to learn how to deploy to JBoss, then this is a good book. Otherwise, a good overview of J2EE and Hibernate, but the examples are very basic. The advanced topics like clustering and session management are missing. So, if you are new to JBoss, and are looking to deploy a J2EE app, then this book will help you. For a more detailed treatment of JBoss and J2EE, look elsewhere.
