Catching Exceptions

I'm using EJB 1.0 and need to know how to catch a DuplicateKeyException in my CMP EJB.
My create method only throws CreateException (superclass of DuplicateKeyException) and when I attempt to use the bean to write a record with a duplicate PK, an SQLException is thrown, but by the time the exception reaches my session bean it's turned into this exception: "CORBA TRANSACTION_ROLLEDBACK 0 No; nested exception is: org.omg.CORBA.TRANSACTION_ROLLEDBACK:".
I can see the duplicate error in the stacktrace: it's nested deep within the above one - but I want to show the user the correct error.
Is there a way to do this?
You could argue that I should try and see if the record is already there, but that seems like a bit of an overhead.
TIA for any help.

There is only overhead is to extract the nested Exception
I would suggest to take out the nested Exception in Session bean and if it is DuplicateKeyException then handle accordingly.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link:
