But I do appriciate this tutorial otherwise
I am new to Hibernate and this tutorial found it quite handy otherwise. 

example not working.
this example doesn't really work, I always get null whenever I run it. However I modified it a bit to make it work. Transaction tx = sess.beginTransaction(); Insurance ins = (Insurance)sess.load(Insurance.class, id); sess.delete(ins); t
