Hi,

I'm trying to write an Java applet that will send an object, via a TCP
socket, to a Java application running on the same machine.  It works
in Opera and Mozilla, but it doesn't work in Firefox - the Java
application appears to receive an incoming connection, but never
actually reads the object.

Any ideas how to resolve this problem?

Code:

/////////////////////// APPLET ////////////////////////////

import java.applet.Applet;
import java.io.BufferedOutputStream;
import java.io.ObjectOutputStream;
import java.net.Socket;

public class AppletClient extends Applet {

   private Socket socket;
   private ObjectOutputStream oos;

   public void start() {
       System.out.println("Hello there!");
       try {
           String host = getCodeBase().getHost();
           socket = new Socket("127.0.0.1", 55000);
           oos = new ObjectOutputStream(new
BufferedOutputStream(socket.getOutputStream()));
           TestObject t = new TestObject("Hello!");
           oos.writeObject(t);
           oos.flush();
           oos.close();
       }
       catch (Exception e) {
           e.printStackTrace();
       }
   }
}

/////////////////////// APPLICATION ////////////////////////////

import java.io.BufferedInputStream;
import java.io.ObjectInputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {

   private static ServerSocket serv;
   private static Socket sock;

   private Server() {
   }

   public static void main(String[] args) {

       try {
           serv = new ServerSocket(55000);

           System.out.println("Server listening on port " +
serv.getLocalPort());
           sock = serv.accept();
           System.out.println("Received connection: " +
sock.getInetAddress()
                                          + ":" + sock.getPort());
           ObjectInputStream ois = new ObjectInputStream(new
BufferedInputStream(sock.getInputStream()));
           System.out.println("Opened input stream.  Attemping to
read object.");
           TestObject t = (TestObject) ois.readObject();
           ois.close();

           t.print();
       }
       catch (Exception e) {
           e.printStackTrace();
       }
   }
}

/////////////////////// OBJECT TO SEND ////////////////////////////

import java.io.Serializable;

public class TestObject implements Serializable {
   private String s;

   public TestObject(String s) {
       this.s = s;
   }

   public void print() {
       System.out.println(s);
   }
}

Thanks,
