Thanks for your reply.
I think ProcessInstanceInfo is mapped because it appear in the persistence.xml file. But I just see that, indeed, the table processInsatnceInfo is not created in the database.
I have no idea why. I can find the class in the libs so it is not due to a missing element.
I give you the war in attachement with the model of the generated tables. If it can give you more clues.
