Session or EntityManager

I'm new to persistence frameworks, and wonder whether to use Java Persistence API or Hibernate in my Java Desktop application.

JPA:

Code:

EntityManager em = Persistence.createEntityManagerFactor ("MyProjectPU").createEntityManager();
EntityTransaction tx = em.getTransaction();
tx.begin();
em.persist(myObject);
tx.commit();

Hibernate:

Code:

Session session = SessionFactoryUtil.getInstance().getCurrentSession();
Transaction tx = session.beginTransaction();      
session.save(myObject);      
tx.commit();

What's the difference between these two ways of saving an object? Why should I use JPA? Why should I use Hibernate?

Thanks in advance!

Well, as you are finding out, the two approaches are very similar! They both are essentially JPA implementers.
