EJBException when calling entityManager.getTransaction()

Question

This is probably something trivial, but I\'d love some help.

I get:

 javax.ejb.EJBException: java.lang.IllegalStateException: Illegal to call this me         


        

Answer 1

You don't need to instantiate the EntityManager by hand, your container does that for you because of the @PersistenceContext annotation. Also, you don't need to begin the transaction manually, it's also provided by your containter. Just use your em field and forget about the other ones.
