What file(s) do you have in the directory?
It sounds like a genuine error in my experience. Most error messages from CMs are much less helpful than this!
We are awaiting for the correct version of SAP JCO files. Below are the files we have in place
sapjco3.jar[EXT SENDER] Case 00476199 While creating connection profile, its showing val [ ref:_00D30MODz._5001O1CTc3m:ref ]
We got the correct files from SAP admin, and hence the connection profilecs could be created and job are running successfully on it.
