hi, u can communicate with a servlet from an applet by, 1.calling the servlet URL using showDocument method of applet context.(pass servlet URL as param) 2.Another way is to open a connection to servlet using URLConnection reference. URL url=new URL("servlet url here"); URLConnection uc=url.openConnection(); i think this will work. u have to prepare the query string yourself if u want to send some values in applet to servlet . try them.
