I looked at all the jar files relating to jboss.remoting on the server. I found one jboss-remoting.jar resided in the server\messaging\lib (595KB, dated today probably because I'd just reinstalled JBoss + JBoss Messaging) I also found another copy of jboss-remoting.jar in server\messaging\deploy\jboss-messaging.sar (848KB, dated 03/28/2007). Are they supposed to be where they are? And why are they different in sizes? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4034779#...
