I think you want to use socket timeouts instead of a timer:

Thread listener = new Thread() {
    ServerSocket ss;

    @Override
    public void run() {
        try {
            ss = new ServerSocket(5000);
            ss.setSoTimeout(2000);
            try {
                while (true) {
                    try {
                        final String text = acceptText();
                        SwingUtilities.invokeLater(new Runnable() {
                            public void run() {
                                jTextArea1.append(text);
                            }
                        });
                    } catch (final Exception ex) {
                        SwingUtilities.invokeLater(new Runnable() {
                            public void run() {
                                setLbl(ex.getMessage());
                            }
                        });
                    }
                }
            } finally {
                ss.close();
            }
        } catch (IOException ex) {
            Logger.getLogger(NewClass.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    private String acceptText() throws IOException {
        Socket s = ss.accept();
        try {
            InputStream is=s.getInputStream();
            try {
                DataInputStream dis=new DataInputStream(is);
                return dis.readUTF();
            } finally {
                is.close();
            }
        } finally {
            s.close();
        }
    }
};
listener.setDaemon(true);
listener.start();
