Hi Tom, I want to add that we've recently made some major fixes on the JBossRemoting / JBossMessaging boundary in Remoting 2.2.3 and JBM 1.4.0.SP3_CP08. They are related to the ConnectionValidator, so they may be relevant to your situation. The same changes will be ported to Remoting 2.5.2. I don't know which versions of JBossMessaging have been updated - you could ask on the "JBoss Messaging" forum (http://www.jboss.org/index.html?module=bb&op=viewforum&f=238). In general, I think that anyone using JBossMessaging should probably upgrade to these new jars. I suppose it's too late for the beer? :) -Ron View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4244479#...
