Help... Super Urgent. Servlet Problem

Question

Anyone can help me this? My servlet wants to connect to another servlet. My supervisor tells me to use socket. This is my code.
Socket socket = new Socket(location, 8210);
          OutputStream os = socket.getOutputStream();
          boolean autoflush = true;
          PrintWriter out = new PrintWriter(socket.getOutputStream(), autoflush);
          ObjectInputStream objIn = null;
          Object obj = null;
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
          out.println("GET "+dir+"?class="+className+"&method="+method+"&machine="+request.getServerName()+"&port="+random+" HTTP/1.1");
          out.println("Host: localhost:8080");
          out.println("Connection: Close");
          out.println();
boolean loop = true;
          StringBuffer sb = new StringBuffer(8096);
          while (objIn==null)
               objIn = new ObjectInputStream(new BufferedInputStream(socket.getInputStream()));
               try
                    obj = objIn.readObject();
                    //Thread.currentThread().sleep(50);
               catch (Exception e)
                    e.printStackTrace();
My supervisor say that as my servlet opens socket connection to the other servlet, the other servlet just have to do outputstream then my servlet can received. I try but can't. Anyone can help me?? Very Urgent. tomorrow is the dateline.

Hi MelonSeed,
I believe that the other servlet needs to open a ServerSocket in order for the two servlets to communicate via a Socket.
Although I haven't tried it, you can open a URLConnection to the other servlet and then open an InputStream for reading the response from the other servlet.
Depending on the URL you use to connect to the other servlet, you will (as I'm sure you know) invoke its "doGet()" or "doPost()" methods.
Also, you may find some relevant examples in Jason Hunter's book, Java Servlet Programming, which are available online.
Good Luck,
Avi.
