No client notification if EJB store fails

Question

We are using Oracle EJB's with bean managed persistence. The client app ends a transaction using the usertransaction.commit and doesn't get any exception if a update failed.
How can we make shure that the client gets an exception if an update fails ?
Thanks in advance

Thanks for taking out the time... really appreciate it.
The problem is as follows:

I have left out code for the generic/primary key classes, if you need that code too, please let me know.
As you can see ejbStore does an update and supposing it fails because the value being updated is too large or the tablespace fills up etc. I would expect to recieve an exception at the client side, but that doesn't happen.
Again I appreciate all the help.
Ashish.
