Bruce, welcome to
Java Ranch!
Are you looking for J2EE 1.4 resources? If so, the book
JBoss At Work most likely provides what you are looking for.
If you are looking for Eclipse guidelines, then perhaps a combination of installing
JBoss Tools and reading the
JBoss Tools Getting Started Guide will help. (I would not go this route if I were a new user - if something goes wrong it is hard to tell if the fault lies with Eclipse, Tools, or the app server.)
If you are looking for very simple tutorials, JBoss In Action might work. It is primarily focused on configuring JBoss AS 5.0, but we do show how to write some simple apps. But it is definitely not a Java EE 5 tutorial.
