Deploy/install custom jmx mbean in tomcat 5.0.19

How does one actually deploy an mbean in tomcat5 so that it is
accessibile via the admin webapp or is this not actually possible?

I have created a TestMBean interface and a simple implementation class
with a get/set and int attribute and copied to
<TOMCAT_HOME>/shared/classes.  Along with the classes I created a
deployment descriptor named mbean-descriptor.xml

<?xml version="1.0"?>
<mbeans-descriptors>
    <mbean name="Stuff" className="Test" description="Test stuff"
domain="Test" group="Resources" type="TestMBean">
        <operation name="getNumber" description="gets the number"
impact="ACTION" returnType="int"></operation>
    </mbean>
</mbeans-descriptors>

I then updated the <TOMCAT_HOME>/conf/server.xml so that the listener
included the new mbean-descriptor.xml.

<Server>
  <Listener
className="org.apache.catalina.mbeans.ServerLifecycleListener"
descriptors="/mbean-descriptor.xml"></Listener>

I get no errors when restarting but also nothing in the admin webapp or
the jmxproxy.

What am I doing wrong?  I had hoped that this would have been as easy
as adding an mbean to JBoss.

Posted by Peter Rossbach <pr...@objektpark.de>.
Currently,

your bean are not started automaticly with this configuration. You must 
write a own LifecycleListener
that start your Mbeans.

Other options is you can configure at engine element is

<Engine mbeansFile="conf/tomcat5-mbeans.xml">
</Engine>

Look at commons-modeler project for documentation:

Here is my example to made a better support possible:

<bean>

    <mbean name="Bean:type=Bean"
        code="org.apache.commons.modeler.modules.MyBean">
        <attribute name="name" value="Peter"/>
    </mbean>
    <jmx-attribute objectName="Bean:type=Bean"
        name="street"
        value="Am Jo"/>

    <jmx-operation objectName="Bean:type=Bean"
        operation="start"/>
    <mbean name="Bean:type=Bean2"
        code="org.apache.commons.modeler.modules.MyBean">
    </mbean>
    <jmx-operation objectName="Bean:type=Bean2"
        operation="setall">
        <arg type="java.lang.String" value="Peter"/>
        <arg type="java.lang.String">Am Jo</arg>
    </jmx-operation>

    <mbean name="Bean:type=Bean3"
        code="org.apache.commons.modeler.modules.MyBean">
        <arg type="java.lang.String" value="Peter"/>
        <arg type="java.lang.String">Am Jo</arg>
    </mbean>

</bean>

I have send a patch for some month to the commons-modeler project 
(http://jakarta.apache.org/commons/modeler/) for better
suppport, but there wasn't accepted.
