I want to know if it is possible to deploy a MBEAN into a JBOSS cluster and if it is possible to see this MBEAN on each clustered JMX server. I mean that each clustered JMX server display the same MBEAN (with the same value) at the same time. If a server is down, I can use the other. MBEAN properties values are not lost.
I want to do a High Availability standalone JMX server.
This functionality doesn't exist out of the box.
You'd have to implement it yourself with an mbean of yours, backed by a JBossCache storage, deployed through the farm service.
