|  | <p>Tomcat uses JMX MBeans as the technology for implementing | 
|  | manageability of Tomcat.</p> | 
|  |  | 
|  | <p>The descriptions of JMX MBeans for Catalina are in the mbeans-descriptors.xml | 
|  | file in each package.</p> | 
|  |  | 
|  | <p>You will need to add MBean descriptions for your custom components | 
|  | in order to avoid a "ManagedBean is not found" exception.</p> | 
|  |  | 
|  | </section> |

|  | <section name="Adding MBean descriptions"> | 
|  |  | 
|  | <p>You may also add MBean descriptions for custom components in | 
|  | an mbeans-descriptors.xml file, located in the same package as the class files | 
|  | it describes.</p> | 
|  |  | 
|  | <p>The permitted syntax for the mbeans-descriptors.xml is defined by | 
|  | the <a href="mbeans-descriptors.dtd">DTD</a> file.</p> |
