In the documentation it says that the jmx-console provides a listing of all MBeans registered with the MBeanServer. but when I try: myrmiadaptor.invoke(new javax.management.ObjectName("JMImplementation:service=LoaderRepository","getLoaders",new Object[]{},newString[]{}); I get a InstanceNotFoundException:JMImpementation:service=LoaderRepsoitory is not registered although it is listed in jmx-console. Why is that? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3983002#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
