As you might have noticed in other posts, JBoss in Action is about configuration and not about development. Thus we do not cover any IDEs. There is a
Java EE 5 Development with NetBeans book out (it was featured as a Java Ranch promo a few months ago), and I know of a book on JBoss Tools that is coming out soon. Also, the JBoss Tools documentation is pretty good - they even have videos showing how to perform various tasks.
