Thanks Manik for looking into this issue--I had another forum post which cleared it up for me: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=109512 I was running a distributed transaction manager with JBoss Cache and none of my transactions were being committed. I'm now running local transactions + a REPL_SYNC policy and letting JBoss do its internal prepare/commit across the cluster. For now I'm handling sync failures in my application as you mentioned. thanks again, Frank[/url] View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053299#...
