when session should be closed?

I have an application, and in the DAO layer where the database transactions occur I have the following sample code:

Code:

public User getUser() {

Session session = HibernateUtil.getCurrentSession();
Transaction tx = session.beginTransaction();
......

tx.close();
session.close();

}

1)I want to ask if I must close session in every DAO method as I am doing above?Or I should never close it?
2)Is session.flush() necessary;
3)When I get session --> HibernateUtil.getCurrentSession();
if there is existing session, Hibernate will not create a new one right?If there is no session, Hibernate will create a new one?

Thanking you in advance...
