Instead of the hack of a hidden frame, use the have your jsp return the
proper http response code to instruct the browser to not update content.
<%
// do all your processing here as long as you send the following
// back as your response
response.setStatus(204);
%>
the 204 response code (No content) can be used by scripts that need to
respond to user clicks, but not send any content back - browsers should
not update their current view when receiving this response.
