当我在ubuntu的摇摆代码中使用DJ浏览器时遇到libwebkitgtk的问题

Question

This is the sample code i'm using for Poc purpose......but i'm not able to go forward in linux environment(if i dont install libwebkitgtk package ) but this code is working fine in windows..but in linux libwebkitgtk is required.

public class SimpleWebBrowserExample {

  public static JComponent createContent() {
    JPanel contentPane = new JPanel(new BorderLayout());
    JPanel webBrowserPanel = new JPanel(new BorderLayout());
    webBrowserPanel.setBorder(BorderFactory.createTitledBorder("Native Web Browser    component"));
    final JWebBrowser webBrowser = new JWebBrowser();
    webBrowser.navigate("/home/mphs/Softwares/eclipse/Home/Softwares/ews/Platform     /src/Sample.html");
     webBrowserPanel.add(webBrowser, BorderLayout.CENTER);
    contentPane.add(webBrowserPanel, BorderLayout.CENTER);
    // Create an additional bar allowing to show/hide the menu bar of the web browser.
    JPanel buttonPanel = new JPanel(new FlowLayout(FlowLayout.CENTER, 4, 4));
    JCheckBox menuBarCheckBox = new JCheckBox("Menu Bar",    webBrowser.isMenuBarVisible());
    menuBarCheckBox.addItemListener(new ItemListener() {
      public void itemStateChanged(ItemEvent e) {
        webBrowser.setMenuBarVisible(e.getStateChange() == ItemEvent.SELECTED);
      }
    });
buttonPanel.add(menuBarCheckBox);
contentPane.add(buttonPanel, BorderLayout.SOUTH);
return contentPane;
}
public static void main(String[] args) throws IOException {
    NativeInterface.open();
    UIUtils.setPreferredLookAndFeel();
    SwingUtilities.invokeLater(new Runnable() {
      public void run() {
        JFrame frame = new JFrame("DJ Native Swing Test");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(createContent(), BorderLayout.CENTER);
        frame.setSize(800, 600);
        frame.setLocationByPlatform(true);
        frame.setVisible(true);
      }
    });
    NativeInterface.runEventPump();
}

}

This is the StackTrace i'm getting...

Install Weblibs in Ubuntu.

command

sudo apt-get install libwebkitgtk-1.0-0

It worked for me. Restart your application after installing this. Hope this will help you too.
