I am beginer in Hibernate and I see often
----------------------------------------------------------------
Session ssn = getSession();
Transaction tsn = ssn.beginTransaction();
// operation
tsn.commit();
ssn.close();
-------------- OR---------------------------------------------
EntityManager em = emf.createEntityManager();
EntityTransaction tx = em.getTransaction();
tx.begin();
// operation
tx.commit();
em.close();
----------------------------------------------------------------
How can I write method WITHOUT getSession(), beginTransaction, tsn.commit(), ssn.close() ? I would like it (container, or I don't know) was responsible for this

THANKS :)))

Even without getSession() anywhere, it's gonna be difficult. But without managing transactions, it's quite simple. For example, use a transactional proxy that will manage your tx demarcation. Spring provides one for instance (see TransactionProxyFactoryBean).

Hi,

If you run from within an app server such as JBoss, you can get the EntityManager injected with a call like so:


Then you can just use calls like em.persist(), em.merge(), em.flush() ... and so on. The container will manage the tranasaction for you.
