what is the preferred way of dectecting a duplicate insert since most hibernate methods throw hibernate expection .. do I check the error code ? Based on this I would like to re-throw the expection as specialized form of a dataaccessexception .. such as a duplicatekeyexception.



Thanks

There is not common method unfortunatly.
This kind of root exception is DB vendor specific. So you'll need to do :
- try to read the entry before inserting it if you expect a high rate of failure
- check the exception cause hierarchy to find your DB specific exception and rethrow your business exception.

I know this could be a cool feature to abstract from the DB, but it probably has to come from the JDBC spec :(
