So Carlo, Are you asking for a *standard* way to get the list of entities. ie a EntityManagerFactory.getEntities() This is not be easy to get for a few reasons, one of them being that you probably want to return some metadata model rather than the plain class and that it would take time to do in the JPA EG (hence likely be -1ed). But if we all agree that it's the only solution, then I am willing to do it. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4221543#...
