Re: Not a NotificationBroadcaster...

I don't know if this is your problem (if not, you may run into this as
well), but I had problems when client and server were not using the same VM
version, due to the different serial id of the ObjectName class. The only
solution I could find was to run them both with the same version.

Subject: Not a NotificationBroadcaster...


Hello List,
 
Some background...
We are moving more to JDK1.5, we have a central JMX MBean repository server
- the rest of app runs in multiple JVMs each of which registers their mbeans
with the central server (via RMI/jsr 160).
 
Admittedly we are still using MX4J 2.0.1 - I will try with 3.0.2 shortly.
My first thoughts are that some of the jsr 160 apis have changed since 2.0.1
and so the upgrade will fix this.
 
The problem we have noticed when the repository server is JDK1.5 and the
client is not, is that we sometimes get this error on the server:
