Not sure if you mentioned the Database version where this runs. A while ago I had written a short article on using ORA_ROWSCN to provide optimistic locking in 10g. Let me know if you need this article and I can email it to you.
The other side of the issue is this: What is your App Server tier that runs this application? If you are running a stateless connection, you really cannot (and should not) expect pessimistic locking to work.
