Subject Re: Cant load coprocessor
Date Wed, 17 May 2017 17:18:15 GMT
Its in the right path and it contains the class, could one of these be the
reason for my error:

   1. the observer class and the endpoint class are in the same jar file
   2. I viewed the MANIFEST.mf file of the jar and it only contains:

*        Manifest-Version: 1.0        Created-By: 1.8.0_102 (Oracle
   Corporation) *


Regards,

Cheyenne O. Forbes
