I'm aware of the configuration changes needed to enable XA recovery for JBoss Messaging resources listed in chapter 8 of the manual ( http://docs.jboss.org/jbossmessaging/docs/userguide-1.4.0.GA/html/recovery.html). I was wondering, however, is there a manual way to trigger the recovery?

I was also wondering about some of the details of the work of the XA recovery - does recovery happen after a container crash/restart cycle? What kind of transactional problems trigger the recovery?(I'd imagine that some transactions are simply rolled back, so something should go really wrong for the recovery to kick in)

Thanks in advance for your help.
