The second option that you are trying makes no sense at all.
You should continue trying with the first one.. looking how to create a persistence unit
and inject the current session that you have available.
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
