There are two ways of doing that.
You can specify the target-attribute in the form that calls your
login-servlet just as you do in a normal link.
...<form action="whoKnows" target="_top">...
That would result in every servletresponse replacing your frameset, even
if the authentication fails. I don't know if that is what you want to
do.
The other way is to send an html-page with a JavaScript overwriting the
location of your top-object, like this. We use it because it allows us
to break out of our frameset conditionally.
public void doPost(HttpServletRequest req, HttpServletResponse res){
authenticate
ServletOutputStream out = res.getOutputStream();
if(authentication failed){
res.setContentType("text/html");
out.println("<html><head><title>DumbPage</title></head>");
out.println("<script>");
out.println("top.location.href=\"http://yourserver.com/theframeset.html\
"");
out.println("</script></html>");
}
else{
res.sendRedirect("http://yourserver.com/tryagain.html");
}
}
Hope it works,
