how can we pass parameter from applet to servlet , I mean in
<applet code=applet.class height=30 width=30>
<param name=adclient value=sun>
in my applet.class i can retrive parameter adclient value using
getParameter("adclient") , then in my applet i am opening urlconnection to servlet like this
URL upurl = new URL("http://comp7:8080/servlet/DisplayerServlet");
URLConnection urlcon = upurl.openConnection();
PrintStream pt = new PrintStream(urlcon.getOutputStream());
str += " got printstream";
now I can retrive every string in servlet that is passed by applet using printstream.print(string) , but how can i get parameter "adclient" value of applet in servlet ,

If you add the parameter to your URL string it will be available as a parameter in the servlet request. For example:
URL upurl = new URL("http://comp7:8080/servlet/DisplayerServlet?adclient=hello");

thanks for your reply , I have done this also
"http://comp7:8080/servlet/DisplayerServlet?adclient=hello" but then applet can not establish connection to url and it throws exception , is there any other way to do this , I also tried to encode the url but then applet throws not protocol exception and can not establish connection with servlet , same with
"http://comp7:8080/servlet/DisplayerServlet?adclient=hello" ,applet can not establish connection to servlet and throws exception , how can i pass parameter to servlet ???
