Hi,
I'm using Hibernate in a web application framework and have a thread local object that has a method used by a lot of different classes during the request cycle to get a hibernate session.

In regards to this I'm stuck on something very simple. When a class requests a session does the thread local object call sessionfactory.createSession() for each getSession() request or does it create the session just once at the begining of the page request cycle and return a reference to that single session object in the getSession() method?

If a session should be created for each call to getSession() then what is the point of using a thread local object?

Thanks for any input.

this is because the session is not thread safe . you can refer ThreadLocal implementation
