Hi, I am sorry if I posted this message in the wrong topic. recently i have moved to jboss clustering. I mentioned the server nodes. while connecting the application from another application it is giving error like "javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException: No ClassLoaders found for: org.jboss.invocation.jrmp.interfaces.JRMPInvokerProxyHA (no security manager: RMI class loader disabled)" can you please suggest me. Thanks in advance View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227505#... Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&a...
