I've a stand alone application that uses hibernate. At the moment, when the application starts, it opens a session, which is closed when the application ends.
However, I suppose that opening and clossing sessions is better. But Why? Which is the advantatge of open/close strategy? Is because the database will work faster?

Thanks!

In hibernate openSession means to get a connection to the db and similarly close session means release the connection.
So this is no strategy, its simply getting/releasing a connection to the db.

Hi,
Hibernate comes with connection pooling. The "hibernate session" does not imply "database session". The connection pool decides, based on config, whether to close/open the physical db connection so don't worry about it. You just need to have a valid "hibernate session" reference and let hibernate do the rest.

Thanks!
