HibernateUtil.getSessionFactory().close()  closes session factory, whereas session.close() closes particular session
I think there is big difference.

This is the explanation of the difference between Sessionfactory and the Session in Hibertnate Tuorial:

http://www.visualbuilder.com/java/hibernate/tutorial/hibernate-architecture-and-api/


1.5.1 SessionFactory (org.hibernate.SessionFactory)

SessionFactory is a thread safe (immutable) cache of compiled mappings for a single database. Usually an application has a single SessionFactory. Threads servicing client requests obtain Sessions from the factory. The behavior of a SessionFactory is controlled by properties supplied at configuration time.

1.5.2 Session (org.hibernate.Session)

A session is a connected object representing a conversation between the application and the database. It wraps a JDBC connection and can be used to maintain the transactions. It also holds a cache of persistent objects,used when navigating the objects or looking up objects by identifier.
