federating mbeans servers

[luca-30]

I've to manage some mBeans in few mBeanServers. At the moment I'm managing them via remote connection and query on remote mbean servers, but I'd like to try mbean servers federating.
I've two doubts:
- How is possible to have a dynamic mirror of my managed Mbeans?...e.g. I connect with mBean servers once, and I'd be notified when an mbean register/deregister;
- What happen when jmx connection shut down?

thanks
luke

There's a chapter of the JDMK tutorial dedicated to federation.
You will find it here.
http://docs.sun.com/app/docs/doc/816-7609/6mdjrf87n?a=view

When you create a cascading agent it creates one proxy per MBean found
in the MBeanServer. This makes the master agent's
MBeanServerDelegate MBean emits an MBean creation notification
for each registered MBean proxy.
The cascading agent also register for MBean creation/deletion
notifications with the sub agent it manages. When an mbean appears
or disappears from the sub agent, a proxy is created or deregistered in
the master agent.  This makes the master agent's
MBeanServerDelegate MBean emits an MBean creation or deletion
notification for that MBean proxy.

If you're federating remote MBeanServers the best way is to use
the CascadingService MBean, which will in turn create
the ProxyCascadingAgents required.
If you're federating local MBeanServers - then you will have
to use  ProxyCascadingAgents directly as shown on my blog.

I believe the cascading agent will unregister the MBean proxies, emit a
notification, and become inactive.
