Question

I’m trying to make a program which listens to the client input stream by using socket programming and timer

but whenever timer executes..
it gets hanged

Please help me out

here is the code…

private void jButton1MouseClicked(java.awt.event.MouseEvent evt) {
    // TODO add your handling code here:
    try

    {
        ServerUserName=jTextField1.getText();
        ss=new ServerSocket(5000);
        jButton1.enable(false);
        jTextArea1.enable(true);
        jTextField2.enable(true);
        Timer t=new Timer(2000, new ActionListener() {

            public void actionPerformed(ActionEvent e) {
                try
                {
                    s=ss.accept();                    
                    InputStream is=s.getInputStream();
                    DataInputStream dis=new DataInputStream(is);
                    jTextArea1.append(dis.readUTF());

                }
                catch(IOException IOE)
                {
                }
                catch(Exception ex)
                {
                    setLbl(ex.getMessage());
                }

            }
        });
        t.start();
    }
    catch(IOException IOE)
    {

    }
}

Thanks in advance

Make the program multi-threaded; one thread listens on the socket, the other one handles the GUI. Use SwingUtilities.invokeLater to let the GUI thread (“event dispatching thread”) do the GUI updates whenever the network thread receives data.
