Hibernate transaction not successfully started

Question

Consider this simple Hibernate scenario:

session = getHibernateSession();
tx = session.beginTransaction();
SomeObject o = (SomeObject) session.get(SomeObject         


        

Answer 1

This is a really old question and I figure you've already solved it (or given up on Hibernate) but the answer is tragically simple. I'm surprised no one else picked it up.

You haven't done a session.save(o), so there is nothing in the transaction to commit. The commit may still not work if you haven't changed anything in the object, but why would you want to save it if nothing has changed?

BTW: It is also perfectly acceptable to do the session.get(...) before the session.beginTransaction().
