| |
| <p>Tomcat 5 uses JMX MBeans as the technology for implementing |
| manageability of Tomcat.</p> |
| |
| <p>The descriptions of JMX MBeans for Catalina are in the |
| org.apache.catalina.mbeans.mbeans-descriptor.xml file.</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="Including your own mbean-descriptor files"> |
| |
| <p>You may configure custom components (e.g. Valves/Realms) by including |
| your own mbean-descriptor file(s), and setting the "descriptors" |
| attribute to point to a ';' separated list of paths (in the ClassLoader sense) |
| of files to add to the default list under ServerLifecycleListener definition |
| in server.xml.</p> |
| |
| <source> |
| <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" |
| debug="0" |
| descriptors="/com/myfirm/mypackage/mbean-descriptor.xml"/> |
| </source> |

| |
| <p>You may also add MBean descriptions for custom components in |
| org.apache.catalina.mbeans.mbeans-descriptor.xml file.</p> |
