Optimistic Locking

[freiburg]

Hello to all,
I'd like to know how I can set jboss for using Optimistic locking instead of pessimistic locking as default. Which xml files I have to modify? Which tags I have to write?
Thank you very much,
Andrea

I'm sorry for the mistake,
in which one you think I can post it?
Thanks,
bye,
Andrea
