It is handled automatically if running within the context of a transaction and it references the XAConnectionFactory.

The JCA adapter already provides this (for JMS) but it is also possible for the scheduled listener/gateway to control the transaction and, from tomorrow, the message aware listeners will support it once again.

It should already be possible to configure the acknowledge mode.  I believe Daniel added this functionality so perhaps he can add a comment to this.
