[jboss-dev-forums] [Design of JCA on JBoss] - Re: Problems JCA JMS inflow issue and tx NotSupported

[weston.price@jboss.com]

As I have said, I believe more than a few times now, the 4.0.5 code was backported randomly and really should never have been done (believe me, I yelled and screamed about this for quite awhile but to no avail). The code in HEAD should really be ported or installed as a patch. 

Please note, just because JCA starts/terminates a transaction does not mean that the onMessage method executes in this context. If NotSupported or BMT is used, the EJB container will suspend the transaction appropriately.

No, it's not. acknowledgement modes are used only in the case of a *non* tranascted session. The spec is merely saying that if the client is using a transacted session, then the ack mode is AUTO_ACKNOWLEDGE which is just simply a convention in this case as has no overall effect.

No, it doesn't.
