Hey Matt,
Yes, you got the point - the mbean server is exposed by management bundle.
Second part is registration of mbean. Because lack of jmx-whiteboard at the
begining of Karaf there was bunch of places where MBeans were registered by
hand (in XML). After all we extracted the "registrar" code and moved it to
management core. Now every Karaf management bundle which going to expose own
mbeans use it in following way:
<reference id="mbeanServer" interface="javax.management.MBeanServer">
<reference-listener ref="mbeanRegistrer" bind-method="registerMBeanServer"
unbind-method="unregisterMBeanServer"/>
</reference>
And then define mbeans
<bean id="mbeanRegistrer"
class="org.apache.karaf.management.MBeanRegistrer">
<property name="mbeans">
<map>
<entry value="domain:type=blabla,name=${karaf.name}"
key-ref="mbean-Implementation"/>
</map>
</property>
</bean>
That's how it's handled in Karaf. Of course the JMX whiteboard is way's better
to use because lack of direct dependencies to Karaf codebase.
