ClassNotFoundException when running ejb3 clustered in 4.0.5
I've been trying to test EJB3 clustering performance on JBoss AS 4.0.5.GA using a small demo application. The application works correctly under a single instance of jboss using the "all" configuration. If, however, I start up a second instance of jboss after having executed an order on the first instance, I get a ClassNotFoundException during startup. I have been able to bypass this issue by copying my classes into the lib directory, but this is not a very workable solution. Any suggestions? The stack trace I'm seeing is below:
