Hello....

I have a system using JBoss + Hibernate that access a database (for example Oracle) and another one in .Net that access the same database, what happens if this second one try to access a data that it's being using
by the first one.

The Hibernate lock tells to the database to lock the objects that i'm using?

Thanks very much for the help...

the best way is that both of your apps use optimistic lock with versionning.
