Error after uploading .jar

[nmodin]

Hi all,

I've run into some issues after uploading a jar file with client code I use in my tests to test a web socket product. The error seems to be related to the .jar itself and how it is loaded as I'm also unable to run even a
very basic test based on the template you get when creating a new script.

I really can't see what see what is going on here so any pointers would be greatly appreciated. Let me know
if you want any additional information


This is the result after creating a new script and just running it as is (the simple HTTP example) after just
pointing the URL used to localhost:8080 (nGrinder admin).

If I remove my jar from the lib folder the example runs to completion with no errors.

This is the error message:
