          How to pass user name and password when I use openConnection method? In java
          doc, this method looks like do not accept these two parameters.
          Thanks
          ----- my code in applet ---------
          URL url = new URL("http://127.0.0.1/xml/index.cfm");
          URLConnection connection = url.openConnection();
          connection.setDoInput(true);
          connection.setDoOutput(true);
          connection.setUseCaches(false);
          connection.setAllowUserInteraction(false);
          DataOutputStream dos = new DataOutputStream(connection.getOutputStream());
          dos.writeBytes("POST " + path + " HTTP/1.0\r\n");
          dos.writeBytes("Referer: http://127.0.0.1/XML/index.cfm\r\n");
          dos.writeBytes("Content-Type:
          multipart/form-data;boundary=---------------------------7d0b414b04\r\n");
          dos.writeBytes("Host: "+host+":"+port+"\r\n");
          dos.writeBytes("Content-Length:" + buff.length()+"\r\n");
          dos.writeBytes("Connection: Keep-Alive\r\n\n");
          dos.writeBytes("-----------------------------7d0b414b04\r\nContent-Dispositi
          on: form-data;name=\"xmlDoc\"\r\n\r\n");
          dos.writeBytes(buff.toString());
          dos.writeBytes("\r\n-----------------------------7d0b414b04--\r\n");
          dos.close();

you need to negotiate Authentication in ur applet code...
          For example:
          If u r using Form based auth u need to send Post a request with j_user_name &
          j_password to the action j_security_check. and when server returns back the
          cookie
          u need to hold it and pass that cookie to the each and every request made to the
          protected application.
          Basically u need to imitate the browser.
