[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Re: Bug in transactional delivery in an MDB

[weston.price@jboss.com]

Adrian's comment are out of date. We always begin a transaction prior to the receive to support JMS providers where this is required (aka WebSpehreMQ). There was code at one point to be able to toggle this behavior on and off, but it has since been removed in the JCA adapter.

That's fine the underlying resource will simply not be enlisted. For inbound this is up to the JCA/JMS adapter which is described below.

I am not sure what you are asking. In the case of inbound messages the transaction behavior depends on the transaction attributes of the MDB. For CMT we use XA, for BMT and CMT/NotSupported we use local JMS transactions to support redelivery in the event of a RuntimeException.
