Yes there is no difference afair in that area in jpa 2. Just to be sure, are you delivering hibernate within you webapp?
By default, we use openjpa so you need hibernate in your webapp. As per the spec and again afair entities get detected and added automatically if and only if they are fine the same persistence archive. So it clearly depends where are exactly the persistence.xml file and the entities. Jlouis Le 6 juin 2013 03:43, "John D.
