1) Is it mandatory to configure klockwork installation in jenkin's global configurations?
if yes what is the meaning of project port (default 1106)? is it server port that we need to fill here?

2) we have upgraded the klocwork plugin for jenkins to 1.41.1 and if we configure it for "Klocwork v9.6 or later" then it doesn't do anything on klockwork server (i.e updating database for this new build) and also klocwork reports are not available for klocwork 9.6 but only klocwork review is available.

3) As we are using Klocwork version 9.6 and it doesn't generate xml file for reports automatically, manually we have generated report file but when we try to use it, it gives error as below:

Starting the klocwork analysis.
