If you don't want to try MERGE, you could always make an anonymous PL/SQL block (which is certainly supported by PL/SQL) and so handle the insert-else-update (or update-else-insert - whichever is the best tradeoff) in one SQL round trip from application server to database; then there will never need to be an exception raised to (and handled by) JDBC.
