Looking for help in understanding this error with my persistence unit (and/or resolving it!).

Application is an originally working jboss5 app being ported to jboss7.

I have re-examined my persistence.xml and looked at my standalone.xml's data source.  I cannot find anything I am doing.

Attached: log generated setting a TRACE level, standalone.xml, and the ear.

I really need to get this working in Jboss 7.  Thanks.
