Craig, Amy - or anyone who knows JMX, I need help :-) I just can't find any way to add an attribute change listener in the whole JMX spec, unless I have the instance of the model mbean. And there is no way to get that instance.
All query and get methods in MBeanServer return ObjectInstance - i.e. name and class, but no 'instance'. There is an 'addNotificationListener' that takes the object name - but the spec ( and implementation ) doesn't allow this to register attribute change listeners, and att changes are not sent to listeners registered with this method ( there is an "all other but attribute changes" in the PDF file ). I'm stuck. I can add some code to the modeler mbean to work around, but the solution won't work for other mbeans. What I want to do is find all attribute changes done via JMX and persist them - if you remember my old proposal. At the moment I'm not very sure it can be implemented. The only possible solution to revive it would be to force all attribute changes to go through a modeler-specific interface or to require the use of the modeler for all mbeans.
