If you by 2pc means two face connect, then yes there is a part of this
in the spec: use local transaction.
As far as I know, the JBoss connector is implemented in such a way that
you have to decide at config/deployment time if your resource adapter is
a "local transaction" one. This is the same for the jms-ra adapter. You
will have to configure a jms-ra adapter that uses local transactions and
use that. I have not turned this on by default (i fact is was a long
time ago since I last tested local transactions with the jms-ra).
