I am not experiencing the "The MBean named exists but does not implement the
NotificationBroadcaster interface"-error that you get as long as I specify the
mbean and not the management interface (type=Management) as a broadcaster.
But my problem is that although the log files tells me that my broadcaster has
been subscribed to by the listener, the listener does not receive any
notifications.
After some investigation I found out that when using a
ListenerServiceMBeanSupport together with a SubscriptionList configuration to
subscribe to notifications sent by an EJB3 service bean it seems like the
ListenerServiceMBeanSupport bean subscribes to the ServiceDelegateWrapper class
instead of the defined bean in the SubscriptionList.
To work around this the following code could be added to the
ServiceDelegateWrapper class:
| @Override
| public void addNotificationListener(NotificationListener listener,
| NotificationFilter
filter,
| Object handback)
| {
|
| if (delegate instanceof ServiceContainer)
| {
| try
| {
| ((ServiceContainer) delegate).invoke("addNotificationListener",
| new Object[] {listener, filter, handback},
| new String[] {"javax.management.NotificationListener",
| "javax.management.NotificationFilter",
| "java.lang.Object"});
|
| }
| catch (Exception e)
| {
| throw new RuntimeException(e);
| }
| }
| }
|
| @Override
| public void removeNotificationListener(NotificationListener listener,
|
NotificationFilter filter,
| Object handback)
| {
|
| if (delegate instanceof ServiceContainer)
| {
| try
| {
| ((ServiceContainer)
delegate).invoke("removeNotificationListener",
| new Object[] {listener, filter, handback},
| new String[] {"javax.management.NotificationListener",
| "javax.management.NotificationFilter",
| "java.lang.Object"});
|
| }
| catch (Exception e)
| {
| throw new RuntimeException(e);
| }
| }
| }
|
This has been tested with the 4.0.5 GA release and it seems to work fine. Is
this a good way of solving this? Any other suggestions?
