Hi, i'm using JBoss 4.0.5 and Java5. I registered my custom MBean on the JBoss MBeanServer like this MBeanServer server = MBeanServerLocator.locateJBoss(); | server.registerMBean(myMBean, new ObjectName("org.example:type=MyNotificationEmitter")); My MBean implements DynamicMBean and extends NotificationBroadcastSupport to emit notifications. I run jboss with the options JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote -Djboss.platform.mbeanserver -Djavax.management.builder.initial=org.jboss.system.server.jmx.MBeanServerBuilderImpl to see the registered MBean on jconsole. Now my problem is, that i can't subscribe for notifications because the notification-tab is disabled. When i select a also registered Service-MBean which extends from ServiceMBeanSupport the notification-tab is enabled and i receive notifications.
