[jboss-user] [EJB 3.0] - EJB3 MBean does not support NotificationBroadcaster

I use EMBEDDED_JBOSS_BETA3 I deploy a MBean EJB3 @Service(objectName = InstrumentManagerMBean.MDBName) | @Management(InstrumentManagerMBean.class) | public class InstrumentManagerImpl extends NotificationBroadcasterSupport | implements InstrumentManagerMBean {... | When I try to add a notification listener I have an exception: MBeanServer mbs = (MBeanServer) MBeanServerFactory.findMBeanServer(null).iterator().next(); | ObjectName oName = new ObjectName(InstrumentManagerMBean.MDBName); | System.out.println(mbs.isRegistered(oName)); | mbs.addNotificationListener(oName, new ClientListener(), null, null); Exception in thread "main" javax.management.RuntimeOperationsException | at org.jboss.mx.server.MBeanServerImpl.addNotificationListener(MBeanServerImpl.java:749) | at fr.biomerieux.nextgen.commandexecutor.Main.main(Main.java:50) | Caused by: java.lang.IllegalArgumentException: The MBean nextGen:service=InstrumentManagerMBean exists but does not implement the NotificationBroadcaster interface. | ... 2 more Object rerieved in MBeanServerImpl is a ServiceMBeanDelegate . It is a delegate around my MBean. This delegate does not implement the NotificationBroadcaster . Consequently I cannot register to notification listeners. Any idea to fix that issue ? I looks like an defect. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4205142#...
