If you are POSTing the form data, I think you'd have to resort to some
javascript. something like:
in frameB (the lower frame), capture the onSubmit(), call a javascript
function in frameA that reads the form data into a bunch of hidden fields in
a form in frameA and then submit the new form.
Like Mike, if anyone has a non-JavaScript solution, I'd love to hear about
it! Actually, I haven't tried setting the target attribute of a form tag,
you might try that too (set it to the name of the frame you want--wonder if
this would work with window names too).
AFAIK, there's no way to do it once your servlet has gotten hold of the
form--no way for your servlet to specify in the response headers what
window/frame it should target =)
