I disagree.

Let's take the example of JBM for a minute. We already have a recovery mechanism in place (we use an XAResourceRecovery instance).

Now whether the transaction was started via JCA or directly by the user is of no consequence.

The JBoss TS recovery manager will just get an xaresource from our XAResourceRecovery instance and return a list of xids, some of these may come from transactions initiated by JCA and others not. It doesn't matter.

In this scenario there is absolutely no need for JCA to do anything.

I think the same logic applies to any resource manager for which you can write an XAResourceRecovery.
