Great, it's good know it  :)  I will discard the second option and continue with the first.

> I remember an article that explains how to create a new persistence unit using a persistence.xml file and then inject the session inside it once is created. You should try that option. 
My partner is doing tested using a persistence.xml file but I think it's different that you mention. Coincidentally he gets the same error I get in my first choice.


EntityManagerFactory emf = Persistence.createEntityManagerFactory( "manager" ); //manager name file persistence
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);



persistence.xml
