It is my problem.. I have an applet that connects against Servlet for authentification stuff.. If authentificacion is good, I need servlet sends the ID of authentified user to the external Web.
I tried in servlet:
Nothing... When I runs the applet, I used it to authentify, but the servlet doesn't redirect to the new web..
Is possible that the problem was I runs an applet, so the servlet returns the form, or RequestDispatcher to that applet and not to the browser??
I could redirects from Applet, but It had security problems...
How is the applet connecting to the servlet - using (Http)URLConnection? If so, then nothing the servlet does will cause the web page to change. The applet needs to do that using Applet.showDocument. If the next web page needs parameters to work with, then those can be appended as GET parameters to the URL passed to the showDocument method.
