Now I'm getting another NoClassDefFoundError: [java] 09:43:40,649 WARN [PerformanceTest] job PING failed: java.rmi.ServerError: Error occurred in server thread; nested exception is: java.lang.NoClassDefFoundError: Could not initialize class org.jboss.jms.client.delegate.ClientConnectionFactoryDelegate | I have ensured that jboss-messaging-client.jar (contains ClientConnectionFactoryDelegate) is being included in the classpath for both the remote RMI executors and the runner jvm's. Any suggestions would be great. Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4108909#...
