|I think you missed one of the old messages (way to many today).

|It appears that if you changes the transaction isolation in the middle of a

|the fly.
well that is EXCELLENT NEWS... ?
you are saying that I can actually change the isolation level on a jdbc
connection for a new transaction ? ( I don't want to change in the middle)
what I want to do is
connection A gets assigned to transaction B
transaction B encompasses bean C
The container gets connection D
Connection D was use with bean E previously
bean C is ISOLATION1 and D is ISOLATION2
my question is can we reconfigure connection D with the new stuff?
you seem to say that yes...because you are aware of problems that arise if
we do it INSIDE a transaction, when I really don't care about this fine a
feature...
