Well, Until recently I was not very fond of open mbeans, since they are
way to cumbersome to create. You had to handcraft the serialization of
data. It was really SNMP-ish. Recent support of open mbeans in Java 6
simplifies it significantly, though...

Hi Francesco,
Notifications in JMX can embed custom data if you like. Take a look
at the javax.management.Notification#setUserData(Object o) and its
related getter. One thing to take into account is that you need to
have knowledge of the type in the client. Hope it helped!!
Hum, JMX best practices recommend to reuse open mbean types
So you can display your notified user data in off-the-shelves JMX
consoles (JConsole, ...)
You can have also a look on

Dear Stephan , Manuel,
I need some hint about the notification mechanism in JMX.
I've figured out that mbean notifications allow to send only simple
messages.
If a client needs to receive complex data it has to pull the data
using, for example, the sequence number obtained in a previous
notification message.
Is this correct or I'm missing something?
thanks in advance
francesco
