about monitor Weblogic 8.1+SP5

The version of Application Manager is Professional Edition.
i had modified 2 parameters in my startWeblogic.cmd according to User GUIDE document.
when i restart my Weblogic, a message had be displayed:
disableMBeanAuthorization is not a recognized attribute......
then i can add a new weblogic monitor in Application Manager 7, but i can not see the JDBCConnectionPool and EJBRuntime monitors.
i had ask this question to the supporter of Application Manager in China, but they tell me there are same problems exist.
who can tell me the solution?
