Swing中的Java YoutubePlayer

我正在尝试将YouTube视频直接嵌入IntelliJ中的JFrame。 我添加了以下库：DJNativeSwing.jar、DJNativeSwing-SWT.jar和SWT.jar。我必须编译三个.jar文件

youtubeplyer_Swing.java：

public static void main(String[] args) {
    NativeInterface.open();
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            JFrame frame = new JFrame("YouTube Viewer");
            frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
            frame.getContentPane().add(getBrowserPanel(), BorderLayout.CENTER);
            frame.setSize(800, 600);
            frame.setLocationByPlatform(true);
            frame.setVisible(true);
        }
    });
    NativeInterface.runEventPump();
    // don't forget to properly close native components
    Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
        @Override
        public void run() {
            NativeInterface.close();
        }
    }));
}

public static JPanel getBrowserPanel() {
    JPanel webBrowserPanel = new JPanel(new BorderLayout());
    JWebBrowser webBrowser = new JWebBrowser();
    webBrowserPanel.add(webBrowser, BorderLayout.CENTER);
    webBrowser.setBarsVisible(false);
    webBrowser.navigate("https://www.youtube.com/v/b-Cr0EWwaTk?fs=");
    return webBrowserPanel;
}

错误：

我做错了什么？

您使用哪些版本的jar文件？我可以使用（for

DJNativeSwing.jar

和

DJNativeSwing SWT.jar

）和（for

SWT.jar

）成功运行您的代码

这描述了一个类似的场景，可能对您很有用。

我已经在我的包所在的文件夹中添加了.jar文件，但它不起作用
