Hi, I deploy a simple MDB (MessageEJB) in JBOSS. In the jboss.j2ee in the JMX console MBean responsible for operating the MessageEJB is JMSContainerInvoker. MBean Name: Domain Name: jboss.j2ee service: EJB plugin: invoker binding: message-driven-bean jndiName: local/MessageEJB@14023097 MBean Java Class: org.jboss.ejb.plugins.jms.JMSContainerInvoker Binding name is binding=message-driven-bean,jndiName=local/MessageEJB@14023097,plugin=invoker,service=EJB In the code I have to look up the Object Name in the below mentioned way | MBeanServerConnection mconn = (MBeanServerConnection)ctx.lookup("jmx/invoker/RMIAdaptor"); | | ObjectName name = new ObjectName("jboss.j2ee:service=EJB,plugin=invoker,binding=message-driven-bean,jndiName=local/MessageEJB@32008150"); | | Object val = mconn.getAttribute(name, "Name"); | ObjectInstance objInst = mconn.getObjectInstance(name); | | System.out.println(name + "\n\tObject Instance Class Name =" + objInst.getClassName()); But for each and every time when I restart /deploy the JBOSS @32008150 is getting changed. And I am getting javax.management.InstanceNotFoundException: jboss.j2ee:service=EJB,plugin=invoker,binding=message-driven-bean,jndiName=local/MessageEJB@14023097 is not registered. How can I solve this problem? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4079538#...
