Hi and I found a script at the below website but appears not to work for me. I'm using the Netbeans IDE and Java Version 6 and the link where I found how to use cookies in Java applets is at http://www.rgagnon.com/javadetails/java-0180.html
However my partial script below (snipped chunky code) seems to make the applet just report an error and not display at all and snipped is a gui as I use a easy drag and drop command method to get the gui which generates the code for me.

import java.io.*;
import java.net.URL;
import netscape.javascript.*;

public class chatroom extends extender {

    public String getCookies() {
      /*
      ** get all cookies for a document
      */
      try {
        JSObject myBrowser = (JSObject) JSObject.getWindow(this);
        JSObject myDocument =  (JSObject) myBrowser.getMember("document");
        String myCookie = (String)myDocument.getMember("cookie");
        if (myCookie.length() > 0)
           return myCookie;
        }
      catch (Exception e){
        e.printStackTrace();
        }
      return "?";
      }

     public String getCookie(String name) {
       /*
       ** get a specific cookie by its name, parse the cookie.
       **    not used in this Applet but can be useful
       */
       String myCookie = getCookies();
       String search = name + "=";
       if (myCookie.length() > 0) {
          int offset = myCookie.indexOf(search);
          if (offset != -1) {
             offset += search.length();
             int end = myCookie.indexOf(";", offset);
             if (end == -1) end = myCookie.length();
             return myCookie.substring(offset,end);
             }
          //else
            //System.out.println("Did not find cookie: "+name);
          }
        return "";
        }




//-----------------------------
// This section is snipped
//-----------------------------



public static void main(String[] args) { }
//do below on startup
    {
    Username.setText(getCookie("gm_team_developments"));
    }
}

Also the applet error is as follows:
