This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I see you placed JBoss AS into Program Files. Bad move. Spaces in path names can cause problems with various Java libraries. I suggest you place JBoss AS elsewhere (I have mine at d:\opt\jboss\jboss-5.0.1.GA).
You should also try starting JBoss AS from the command line. Once that is running properly we can tackle getting it to run in Eclipse.
