I will check that out.

You don't understand that it can have nothing to do with a RDBMS. I'm
not talking about transaction control within the context of a database
within a RDBMS. As I wrote to another user on this list, say you have
two database servers and you need to implement a process which operates
on each database in order. Maybe you move an item from on to the other.
What if the second operation fails? Natually you want to roll-back to
before the operation on the first. That's what J2EE transactions are
about. See how RDMBS transactions are a different deal in this
situation?
