Hi.
Not sure what you mean by "SELECT FOR UPDATE".
Two instances of the same Entity Bean over the same row still have different
transaction contexts.
You may expect isolation from transactions so you can rely on them.
If two users try to update the row almost at the same time from different
instances of the same class of Entity Bean then the standard transaction
approach applies.

Regards.
