Hello,

I using JBoss 3.2.4 with Hibernate and I seem to be having a problem getting the 
TreeCache to participate in the containers transaction.   I seem to be getting the 
following exception with each transaction.  I've also added my treecache.xml file.  Is 
something missing from that file that is causing this error?

17:19:26,912 ERROR [TreeCache] getCurrentTransaction(): registration with transaction 
failed
