Hi experts,

Some time ago I installed a label security feature on 8.1.7.4 database. Then when I try to run policy manager by typing "opm" it straight away gave me this kind of error:

Class not found: oracle.sysman.LbacClient.LbacClientApp

nothing more. just one line error and the GUI didn't show up.

Have you guys encountered similar problems before with other products GUI? I suspected it is because of a corrupted JRE but customer wanted to know the root of the problem first.

Thanks for the help.

Ric
