JList dynamically adding items

Question

I am inserting items into a Jlist dynamically by reading from a network port .The items get added but my problem is list box always shows the top portion of the list.
Is there any way i can make the list to scroll down as and when i add items into it.
Thanks

No its still not working i am doing in an applet

public class QueryResults extends JApplet implements Runnable{
        Thread resultReader =null;
        Socket sock =null;
        BufferedReader in =null;
        PrintWriter pw =null;
        JList resultList = new JList(new DefaultListModel());
        JScrollPane sp =new JScrollPane(resultList);
        public void init(){
            try{
                sock= new Socket("localhost", 4444);
                pw=new PrintWriter(sock.getOutputStream(), true);
                in=new BufferedReader(new InputStreamReader( sock.getInputStream()));
                resultList.ensureIndexIsVisible(resultList.getModel().getSize());
                sp.setAutoscrolls(true);
                Container contentpane=getContentPane();
                contentpane.setLayout(new FlowLayout());
                contentpane.add(sp);
            }catch(IOException e){
                e.printStackTrace();
        public void start(){
            resultReader=new Thread(this);
            resultReader.start();
        public void run(){
            try{
                String line;
                while((line=in.readLine())!= null){
                    ((DefaultListModel)resultList.getModel()).addElement(line);
                    resultList.repaint();
                    SwingUtilities.invokeLater(new Runnable(){public void run()
                        sp.getVerticalScrollBar().getModel().setValue(sp.getVerticalScrollBar().getModel().getMaximum());
                        //spane.getVerticalScrollBar().setValue(spane.getVerticalScrollBar().getMaximum() );
                    //resultList.ensureIndexIsVisible(resultList.getModel().getSize());
                    //resultList.repaint();
                    //sp.getVerticalScrollBar().getModel().setValue(sp.getVerticalScrollBar().getModel().getMaximum());
            }catch(IOException e){
                e.printStackTrace();
        public void stop(){
            try{
                pw.close();
                in.close();
                sock.close();
            }catch(IOException e){
                e.printStackTrace();
