session = sessionFactory.getCurrentSession(); problem

What is the difference between

Code:

Session openedSession = HibernateManager.openNewSession();

and

Code:

sessionFactory.getCurrentSession();

method.

Is the latter one, would open a session, if there isn't an opened session.
I know that latter one also need a configuration line in hibernate.cfg.xml file. ( <property name="current_session_context_class">thread</property>) And if I didn't write this line hibernate give me an error. Do I really need this line in my hibernate.cfg.xml file and How can I handle session management in my HibernateManager code ?

I am not really sure for this issue and need experts advices.

Thank you

Here's actually an interesting discussion on that very topic at JavaRanch:

The getCurrentSession() method looks at the current context to see if a session is stored in there. If there is one, it uses it, and if there isn't a session in the current context, it creates a new one and saves it in there.

On the other hand, openSession does not try to store the session, or pull the session from the current context. I think the expectation is that you, as the developer, are going to store the session in a special scope of your own.
