Hi,

I started trying Gatlin quite recently. I am working on windows 7 ans using Gatling 2.2.4.  
I tried a recording using HAR mode and converted it into simulation file . I am having trouble executing the gatling.bat file . I have added the Java path wherever needed .  
But i keep getting this error “Error: Could not find or load main class goto”.  
Kindly let me know what was the mistake.

Thanks  
Spandana
