Hi John, I tried your example and I was able to deploy it to JBossAS 4.2.2 using JBossWS 2.0.2. (but I removed @Clustered annotation, because I don't have cluster configured on my local machine.) I compiled your service classes using JBoss AS 4.2.2 classpath. Did you try to remove @Clustered annotation? Maybe it is causing your problems. Do you have your cluster environment configured properly? Richard View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4107866#...
