help with hibernate (Iknow it's off topic)

[Yucca Nel]

but the following forums seem dead.

I am horrified by the following code causing a untime exception because I want 
to make sure hibernate session is closed but even though the session is null, 
it appears to be open still?


finally {
            if(session!=null){
                session.close();
            }
        }
/I don't want a memory leak but it appears that the following exception is 
thrown with the above code...
