I think I see a potential problem. You are deploying EJBs so I'd imagine that you are deploying them as an EAR file, but you specify your loader repository in jboss-web.xml rather than jboss-app.xml. I don't think that will apply to the EJBs if it's even picked up by JBoss at all. Without that your EJBs would not be bound under testPro and the exception you are getting would make sense.
