Have I misinterpreted this?  I assume that if the tx is controlled by jboss
(ie, I'm inside a SLSB with appropriate configuration) that autocommit will
be _off_ yes?  I've always run under the assumption that autocommit is off
and all I need to do is call setRollbackOnly as required.

Could you clarify under what circumstances the JCA spec requiring autocommit
to be on will change this behaviour?

thanks
