entityManager.getTransaction().rollback() detaches entities?

Question

I have the following piece of code:

EntityManagerFactory emf = Persistence.createEntityManagerFactory(\"test\")
EntityManager entityManager = emf.createEntityMan         


        

Answer 1

In a PersistenceContext of "Transaction" then commit/rollback will detach objects used in the transaction. In PersistenceContext of "Extended" then commit/rollback do nothing like that, and objects are detached at close of the EM. Depends on your context
