Instead of doing this:
Onbeginrequest() { mysession=factory.opensession();
mysession.begintransaction(); }
Session getSession() { return mysession; }
Do this:
Onbeginrequest() { mysession=null; }
Session getSession() { if (mysession==null) {
mysession=factory.opensession(); mysession.begintransaction(); } return
mysession; }
Then when an error occurs just reset mysession back to null and next time
you need one you will get a fresh one
