EJB problem

[Dono Learn To Java]

hi all
I have a problem using Eclipse 3.0.1 using Lomboz and JBoss 4.0.1. I've tried to create EJB Project, but i get the message bellow when I'm doing "debug server". I've tried all possible modification on creating EJB by changing the path, the server but there are so many error message.

I need help from you to solve this problem. Thank's
