[jboss-user] [Management, JMX/JBoss] - RuntimeMBeanException caused while trying to do getAttribute

Hello, I am getting RuntimeMBeanException when i do getAttribute from ManagementBean(MEJB). Also i think this RuntimeMBeanException has occurred due to NullpointerExeception. I was using getattribute to get the Number of messages in the Queue or Topic. We send, receive the messages in the whole night and this Exception has occurred only once. Anybody knows what could be the problem? At what condition this might happen. regards Sanjeeth S View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4028661#...
