deploy a gwt application into jboss AS7

Question

When I'm trying to deploy my gwt application (which I transformed to a web dynamic project) I got this error :

I am not using any persistence, and I don't need to use it.
Help me please!

While your gwt application has created, you may be select Use Google App Engine . Because of it, there were files created like `persistence.xml' etc.

If you want simple gwt application, Don't tick on Use Google App Engine option.
