If all you want to do is expose a Spring bean as an MBean it's actually=20
pretty easy and doesn't require any code.

Create an MBeanServer registered as a bean

=A0 <bean id=3D"mbeanserver"
=A0 =A0class=3D"org.springframework.jmx.factory.MBeanServerFactoryBean">
=A0 =A0 <property name=3D"defaultDomain"><value>MyDomain</value></propert=
y>
=A0 </bean>

Wrap an MBean adapter around my repositorymanager bean (not shown),=20
which is a completely ordinary java object. In this case, public=20
methods are exposed as attributes/operations. Alternatively, metadata =A0
can be used.

=A0 <bean id=3D"mbeanadapter"
=A0 =A0class=3D"org.springframework.jmx.JmxMBeanAdapter">
=A0 =A0 <property name=3D"server"><ref local=3D"mbeanserver"/></property>
=A0 =A0 <property name=3D"beans">
=A0 =A0 =A0 <map>
=A0 =A0 =A0 =A0 <entry key=3D"MyDomain:id=3DRepository">
=A0 =A0 =A0 =A0 =A0 <ref bean=3D"repositorymanager"/>
=A0 =A0 =A0 =A0 </entry>
=A0 =A0 =A0 </map>
=A0 =A0 </property>
=A0 </bean>

Create a connector listening, by default, on=20
service:jmx:jmxmp://localhost:9876 (this requires=20
jmxremote_optional.jar)

  <bean id=3D"jmxconnector"
    class=3D"org.springframework.jmx.support.ConnectorServerFactoryBean">
    <property name=3D"server">
      <ref local=3D"mbeanserver" />
    </property>
    <!-- This is the default URL anyway -->
    <property name=3D"serviceUrl">
      <value>service:jmx:jmxmp://localhost:9876</value>
    </property>
    <property name=3D"threaded">
      <value>true</value>
    </property>
    <!-- Ensure the connector thread doesn't keep the
         servlet container running -->
    <property name=3D"daemon">
      <value>true</value>
    </property>
  </bean>
