XMBeans and ServiceMBeanSupport problems with attribute chan

[fpa1974]

I have an XMBean that used to be implemented as a POJO (no inheritance from any JBoss support classes). I also have a listener in the system that waits for the automatic attribute changes that the XMBeans emits. Everything worked like a charm. This was until I decided to extend ServiceMBeanSupport with my regular XMBean POJO. From this moment on all the automatic attribute change notifications stopped working. I have a suspicion that the problem is related to the fact that now my POJO is a NotificationEmitter (by inheriting from ServiceMBeanSupport).
I also looked/debugged JBoss code and noticed that model mbeans have their own subscription list (different from the one in ServiceMBeanSupport/NotificationBroadcasterSupport) and the internal subscription list in the model mbean class implementation is being used to fire the attribute change notifications (and not the one in ServiceMBeanSupport).

BTW I am using JBoss 3.2.6.

Any ideas about this problem would be appreciated.

Thanks,

I think I've solved this at 3.2.7, see

Thanks a lot!

In the meantime since I cannot switch to 3.2.7 yet I will have to devise a fix. I think the easiest way is to get the code from ServiceMBeanSupport minus the notification broadcaster part and inherit from that instead.

you'll have to remove the sendNotification() calls in your modified ServiceMBeanSupport

Yes, I already did that! And it works like a charm :)

Thanks again,
