How do you handle Hibernate in Enterprise environment

[VenkataPrasad Regula]

In any Hibernate tutorial we find the following steps

1. Create a Session Factory
2. Create a session
3. Do the unit of work
4. Close the session.

In an enterprise environment, we have the following issues as
1. How to create the session for different pages
2. If the page has multiple tasks to be done on a single page
3. If the result is returned to a page we return the POJO, which indicates the session will still be open. How to close the session
4. If the session is closed before return we cant return to the results page as the whole conversation gets closed by session.close()
