I assume what you're after is the Last Resource Commit Optimization, but there may be a couple of things mixed in here.
Firstly, you don't have a choice as to what kind of resources are registered with JBoss TM - they have to be implementations of the XAResource interface since you're coming in through JTA. So, and here's where some of the confusion resides, if you want to register a non-XAResource participant but it's still two-phase aware, then you'd have to wrap it in an XAResource and ensure it obeys that protocol. However, if what you've got is a resource (derived from, or wrapped by XAResource again, of course) that isn't two-phase aware, then you do need to LRCO. And fairly obviously you don't necessarily commit on the last resource. Unfortunately it's not a required part of X/Open XA or JTA (JTA doesn't even mention it). Neither is ordering of participants in the transaction's intentions list, which you'd like to do for a number of other reasons. I don't think JBoss TM supports it. If that is the case, the Arjuna+JBoss integration may be worth a look.
