Answer 1

public static void main(String[] args) {
    // Logo
    //
    JWindow frame = new JWindow();
    JLabel info = new JLabel("Initializing....", JLabel.CENTER);
    info.setForeground(Color.black);
    /** The default logging file = resources/logging.cfg */
    final String DEFAULT_LOGGING_FILENAME = "Log4j.xml";    try {
      {
        String loggingFileName = System.getProperty("logging");
        if (loggingFileName == null)
          loggingFileName = DEFAULT_LOGGING_FILENAME;
        URL fileURL = ClassLoader.getSystemResource(loggingFileName);
        DOMConfigurator.configure(fileURL);
        //frame.setUndecorated(true); // JDK 1.3
        ImageIcon logoIcon = ImageLoader.getImageIcon("splash.gif");
        JLabel lab = new JLabel(logoIcon) {
          public void paint(Graphics g) {
            super.paint(g);            Graphics2D g2 = (Graphics2D) g;
            g2.setRenderingHint(
                RenderingHints.KEY_ANTIALIASING,
                RenderingHints.VALUE_ANTIALIAS_ON);            g2.setFont(new Font("Arial", Font.BOLD, 15));
            g2.setColor(Color.WHITE);
            Composite originalComposite = g2.getComposite();
            g2.setComposite(
                AlphaComposite.getInstance(
                AlphaComposite.SRC_OVER,
                0.5f));
            g2.drawString("Workflow Designer", 12, 32);            //g2.setFont(new Font("Arial", Font.BOLD, 27));
            g2.setFont(new Font("Arial", Font.BOLD, 15));            g2.setColor(Color.BLACK);
            g2.setComposite(originalComposite);
            g2.drawString("Workflow Designer", 10, 30);            g2.setFont(new Font("Arial", Font.BOLD, 12));
            g2.drawString("v " + Version.getVersion(), 25, 50);
            g2.setFont(new Font("宋体", Font.BOLD, 10));
            String companyName = " " + Translator.getString("CompanyName");
            g2.drawString(
                "(c) "
                + Calendar.getInstance().get(Calendar.YEAR)
                + companyName,
                10,
                70);
          }
        };        frame.getContentPane().add(lab, BorderLayout.CENTER);
        lab.setLayout(new BorderLayout());
        lab.add(info, BorderLayout.SOUTH);
        lab.setBorder(BorderFactory.createRaisedBevelBorder());
        info.setPreferredSize(new Dimension(lab.getWidth(), 20));
        frame.pack();
        Utilities.center(frame);
        frame.show();
        //GPDesigner.init();
        //info.setText("Starting...");
        info.setFont(new Font("宋体", Font.BOLD, 12));
        info.setText("请  稍  等 ...");
      }      info = null;
      frame.dispose();
      frame = null;
      GraphModelProviderRegistry.addGraphModelProvider(
          new DefaultGraphModelProvider());      new GPDesigner();
    }
    catch (Exception e) {
      info.setText(e.getMessage());
      e.printStackTrace();
      System.err.println(e.getMessage());
    }
    finally {
      if (frame != null)
        frame.dispose();
    }
  }仔细看一下，应该对你有用
