You can run the WebRun test case via two mechanisms:
java WebRun -l http://www.sinz.org/Michael.Sinz/WebRun/ test<args>
java WebRun http://www.sinz.org/Michael.Sinz/WebRun/test.html
The first case has you providing the class to run and its arguments.
The second case has you just providing this web page which has a meta tag in it that provides the arguments.
