    Ejb3Configuration => creating em and emf

    Olivier Vincent Newbie

      Hello,

      I don't want to use anymore the persistence.xml file because the use of jar-file doesn't work (with relative path) if I have the entities on another jar-file in the same ear.

      So I'm trying to create my own entityManagerFactory and entityManager to inject them into JNDI.

      So the code is above.

      But I have still this warning and no SQL Query works ! :
      "WARN [AbstractEntityManagerImpl] Calling joinTransaction() on a non JTA EntityManager"

      So, how can I force the transaction-type to JTA ??? Or another solution ?

      Thanks,

      Olv
