Hello,
I am trying to repackage a small EJB3 application moving the EJB jar file to

EJB3.1 specs.
The Entity EJBs in that jar are recognized OK as hibernate logs show, but JBoss
seems to ignore the Stateless Session

I don't use native queries as my components are supposed to work, for example,
both with SQLServer and MySQL. I change the mappings in persistence.xml and
