    No Persistence provider for EntityManager

    dheeraj segapalli Newbie

      HI,
      I have tried to test my application using Testng methods.
      But my tests are failed and it returns the error::

      javax.persistence.PersistenceException: No Persistence provider for EntityManager named...

      Can anyone tell me why I am unable to test even when the persistence file is correct.

      How can I solve this?

                  Hi Loaone,

                  I suppose you will not get an answer if you recycle such old thread. Maybe your JBoss version and environment is also very different.

                  You should open a new thread and provide informations about your problem.
