appletter og sockets

Hej. Jeg er i gang med at lave en chat i en applet. Men det går ikke så godt, for når jeg prøver at få min applet til at connecte til min server så crasher appletten. Jeg forstår det ganske enkelt ikke. Det virker fint nok hvis jeg kører chatten i en JFrame, men i en applet eller JApplet vil den bare ikke. Her følger koden :

private DataOutputStream out;
private Socket stub;
private TextField inputField;
   
    public void init()
    {
    setLayout(new BorderLayout());
    inputHandler actionHandler=new inputHandler(this);
   
   
    TextArea outputArea=new TextArea(10,30);
    outputArea.setEnabled(false);

    inputField=new TextField(70);
    inputField.addKeyListener(actionHandler);
   
    Button send=new Button("Send");
    send.addActionListener(actionHandler);

    Panel write=new Panel();
    write.add(inputField);
    write.add(send);
    add(outputArea,BorderLayout.CENTER);
    add(write,BorderLayout.SOUTH);
    inputField.requestFocus();

inputField.setText(""+getCodeBase().getHost());

        try
        {
        stub=new Socket(ip,port);
        in=new DataInputStream(stub.getInputStream());
        out=new DataOutputStream(stub.getOutputStream());
            while (true)
            {

            }
        }
