Introduction

Tomcat 5 uses JMX MBeans as the technology for implementing manageability of Tomcat.

The descriptions of JMX MBeans for Catalina are in the mbeans-descriptor.xml file in each package.

You will need to add MBean descriptions for your custom components in order to avoid a "ManagedBean is not found" exception.

Adding MBean descriptions

You may also add MBean descriptions for custom components in a mbeans-descriptor.xml file, located in the same package as the class files it describes.

  <mbean         name="LDAPRealm"
            className="org.apache.catalina.mbeans.ClassNameMBean"
          description="Custom LDAPRealm"
               domain="Catalina"
                group="Realm"
                 type="com.myfirm.mypackage.LDAPRealm">

    <attribute   name="className"
          description="Fully qualified class name of the managed object"
                 type="java.lang.String"
            writeable="false"/>

    <attribute   name="debug"
          description="The debugging detail level for this component"
                 type="int"/>
