>The user through which I logged in is 'User' and it has all the possible authorizations.
I don't understand what your login user has to do with this. What user did you input into the job definition in the XSAdmin tool. This is the user which the job will run as.
>After I Activate and save the Job in xs admin tool, I must get the required output.Right?
Required output? From the XSAdmin tool you will only see the job log - success or failure of the job. You said earlier you were getting an error message.
