[Paul Clapham]

Line 20 of your code is this one, right?

finally{sess.flush();

(Check that in your Java editor. If that isn't line 20, then look at the line of code which is line 20.)

If so, that means that the "sess" variable is null. It hasn't been assigned a value.

[Mary Chellapa]

yes it is, but sess.save worked so sess may not be null

but i do think the issue may be with hibernate.cfg.xml
cant figure out what

[Mary Chellapa]

What should be directory structure?
is my cfg.xml placed in wrong place ?
