First, let me say that I haven't followed this thread too closely, nor
did I look at the original poster's problem/situation too deeply.
But I think you're looking at this all wrong. A servlet does not open
new windows, it just responds to a request with HTML (generally).
What you need to do is figure out what HTML you need, and then figure
out a way you can have a servlet generate it. I'd even suggest going
so far as to manually create the HTML (perhaps a simplified version of
it), and use that to guide you. Things can get tricky when you're
dealing with frames, and sometimes you need to get back to basics to
figure things out.
