While adding a Custom Application Monitor, the WebLogic Model MBeans are not listed for configuration. What can I do?

For WebLogic Model MBeans to be displayed in CAM, perform the following steps:

1. Copy the file weblogic.jar from WebLogic installed directory (eg: C:\bea\weblogic81\server\lib\weblogic.jar). Rename this file as     weblogicclient7_0_common.jar and place it       under <Applications Manager Home>/working/classes directory.
2. Edit the file startApplicationsManager.bat/.sh located in <Applications Manager Home> directory. Set the system property as following
      -Djava.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
3. Restart the Applications Manager.
