Hi Lee,
You need to run your script within the Grinder script execution
environment, not directly using Jython. There are a lot of supporting
Grinder classes that your script depends on. Have a look at the User Guide
here:
http://grinder.sourceforge.net/g3/getting-started.html
Specifically you need to create the start scripts "setGrinderEnv.cmd"
and "startAgent.cmd"
(assuming you're using Windows).
Also look at the docs for the grinder.properties file here, which is where
you tell The Grinder where your test script resides:
http://grinder.sourceforge.net/g3/properties.html
Regards,
Gary
