[Saravana Kumar]

I have installed Jensor1.8. I created a project called TEST using the jensor GUI. And when i try instrumenting a WAR file it throws the below error :

I tried including jensorjdk14-v18-win32.jar in WEB-INF\lib folder in my WAR before instrumentation. But the same error appears even then.

Can you please help me in this issue.

Hi,

    We are trying to replicate the issue at our end, but have not succeeded till this point in time.
    However one point is that no need to include the jensorjdk14-v18-win32.jar in the WEB-INF\lib directory of the war file.
    We would revert back once the resolution is reached.

Regards,
Suresh.
