I would like to make a webapp to put it in my portfolio.

as you can tell, I am a newbie.

I don't know why or what make the persistence.xml block the deployment. but that's what jboss said it's persistence unit.

Could someone help me out?

below is my persistence.xml and the stack trace.

<?xml version="1.0" encoding="UTF-8"?>
