Subject [jira] Created: (ARIES-430) Whiteboard registration support for JMX DynamicMBeans
Date Wed, 29 Sep 2010 09:01:32 GMT
Whiteboard registration support for JMX DynamicMBeans

                 Key: ARIES-430
             Project: Aries
          Issue Type: New Feature
          Components: JMX
            Reporter: Felix Meschberger

As proposed on dev [1] I have hacked together a small piece of code which implements support
for the whiteboard pattern for registering MBeans with MBean servers.

The code is in my Sling whiteboard at
but is intended to be added to the Aries JMX functionality.

The single-class implementation picks up DynamicMBean servies registered as "".
Each such service is registered with each registered MBeanServer service (similar to how the
framework MBeans are registered by jmx.core). The JMX ObjectName can either be provided with
a "jmx.objectname" service registration property (String type) or the DynamicMBean may implement
the MBeanRegistration interface in which case the ObjectName is provided by the preRegister
method during registration.

This is just a first hack which has not really been tested but mainly serves to show the idea.
It is currently implemented as a Declarative Services component but may as well be implemented
as a regular class using ServerTracker instances and instantiated by the BundleActivator (which
may be a good idea to make this as widely usable as possible - for example in Sling we don't
currently use Blueprint, so a Blueprint based implementation would be a no-go for us ;-) )

If there would be interest in this, I would try to test and validate this piece with the hopes
to get a release soon (may be released independently, hint hint ;-) )
