Re: Register a bean as a MBean (JMX)

[Charles Moulliard]

The code that I tried to use is for Karaf 3.X.

The following blueprint file works fine :

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
           xsi:schemaLocation="
           http://www.osgi.org/xmlns/blueprint/v1.0.0
              http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd";>

    <!-- ServiceMBean -->
    <bean id="serviceMBean"
class="com.fusesource.poc.service.impl.MyService"/>

    <service ref="serviceMBean" auto-export="interfaces">
        <service-properties>
            <!-- Karaf 3.x -->
            <entry key="jmx.objectname"
value="com.fusesource.poc.service:type=service,name=feedback" />
            -->
        </service-properties>
    </service>

    <!-- Reference to the MBean Server -->
    <reference id="mbeanServer" interface="javax.management.MBeanServer">
        <reference-listener ref="mbeanRegistrer"
bind-method="registerMBeanServer" unbind-method="unregisterMBeanServer"/>
    </reference>

    <!-- MBean Registrer -->
    <!-- method destroy has been added after karaf 2.2.x
destroy-method="destroy" -->
    <bean id="mbeanRegistrer"
class="org.apache.karaf.management.MBeanRegistrer" init-method="init">
        <property name="mbeans">
            <map>
                <entry
value="com.fusesource.poc.service:type=service,name=feedback"
key-ref="serviceMBean"/>
            </map>
        </property>
    </bean>

</blueprint>
