# MBean Descriptor How To

Table of Contents

> - Introduction
> - Adding MBean descriptions

Introduction

> Tomcat 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"/>
>         .
