Hi Tharaka,

Before asking session.getCurrentSession() you need to perform session.openSession() first.

Hope this resolve your issue.

@King
That's incorrect. You can get the currentSession even if there is not one opened, it will open it for you and store in the context you configured it to be. That's whole point of using it.

@Tharaka
Your error message comes from the line:

Code:

session.close();

, you need to remove that. Hibernate session will auto close when you invoke

Code:

trans.commit();

. So you are closing a session that's already closed, thus the error msg.
