JBoss 4.0.4GA. Java 5.07 We have a 7 machine cluster. When we start our cluster, the first machine starts and deploys the application. I think we have some code that brings an entity bean into cache when a service is started. On each subsequent machine, when we start jboss, the cache discovers the other node and when it transfers the state, we get a NoClassDefFoundError because the machine starting up hasn't deployed the application yet. My question: Is this a big deal? Will it synch up at another time? I mean, what happens if you want to add a machine to a all-ready running cluster? You would see the same thing, right? Thanks for your help, Michael View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3995300#...
