Has anyone successfully utilized JBoss 3.0 CMP with a database schema utilizing identity columns? Specifically with MS SQL Server? If JBoss does not have this capability, can someone point me to a reasonably-priced O/R mapper that can do this and will integrate with JBoss?

Please refrain from directing me to patterns for PK generation -- this is not what I need. I need to deploy on top of an existing DB schema with no modifications.

Thanks in advance.
