Httpunit error while running javascript on orkut

Hello folks,

I was trying to use Httpunit to log into my orkut profile. But then ocurred
a error. Here is the source code and the stack trace of the error. Sorry if
this is a lame question, but I'm unexperienced on web programming and
alikes, and i'm totally lost on what I can do. Thanks for the attention ;-)

        form.setParameter("Email", "[email protected]");

                    form.submit();
