在java應用程序中嵌入瀏覽器

最近做一個繳費的項目，直接用瀏覽器做終端不安全，

需要把瀏覽器嵌入到java application中，目的是爲了不把瀏覽器中的

工具欄，收藏夾，地址欄等去了，讓用戶不能刷新，關閉程序等。。。

方式一：用jdic開源組件，這種方式有個缺點，不支持firefox,如果把默認瀏覽器設爲firefox就會出錯

具體代碼如下：

import java.awt.BorderLayout;
import java.net.MalformedURLException;
import java.net.URL;

import javax.swing.JFrame;
import javax.swing.JPanel;

import org.jdesktop.jdic.browser.WebBrowser;
import org.jdesktop.jdic.browser.WebBrowserEvent;
import org.jdesktop.jdic.browser.WebBrowserListener;

public class MainFrame extends JFrame{

private WebBrowser webBrowser;
private JPanel jPanel;
private String url;

public MainFrame(String name,String url){
     super(name);
      this.url = url;
     init();
      //關閉
      this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

public void init(){
       //隱藏JFrame的標題欄，必須在顯示之前調用，否則就會拋出異常
       //this.setUndecorated(true);
      webBrowser = new WebBrowser();
       //註冊各種偵聽器
        webBrowser.addWebBrowserListener(
            new WebBrowserListener() {
            public void downloadStarted(WebBrowserEvent event) {;}
            public void downloadCompleted(WebBrowserEvent event) {;}
            public void downloadProgress(WebBrowserEvent event) {;}
            public void downloadError(WebBrowserEvent event) {;}
            public void documentCompleted(WebBrowserEvent event) {;}
            public void titleChange(WebBrowserEvent event) {;}
            public void statusTextChange(WebBrowserEvent event) {;}
            public void windowClose(WebBrowserEvent webBrowserEvent) {
            }
        });

      //打開某個網頁
        try {
        webBrowser.setURL(new URL(url));
        } catch (MalformedURLException e) {
            System.out.println(e.getMessage());
            return;
        }

        jPanel = new JPanel();
        jPanel.setLayout(new BorderLayout());
        jPanel.add(webBrowser, BorderLayout.CENTER);
        this.getContentPane().add(jPanel, BorderLayout.CENTER);
        this.pack();
        //全屏
        this.setExtendedState(JFrame.MAXIMIZED_BOTH);
        //this.setSize(500,500);
        this.setVisible(true);
}

public static void main(String[] args){
      String url = "http://...";
      new MainFrame("電信營業廳繳費終端",url);
}

}

方式二：用 DJ Native Swing 組件(http://djproject.sourceforge.net/ns/index.html),支持firefox

import java.awt.BorderLayout;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

import chrriis.common.UIUtils;
import chrriis.dj.nativeswing.swtimpl.NativeInterface;
import chrriis.dj.nativeswing.swtimpl.components.JWebBrowser;

public class EagleBrowser extends JPanel {

private JPanel webBrowserPanel;

private JWebBrowser webBrowser;

private String url;

public EagleBrowser(String url) {
     super(new BorderLayout());
     this.url = url;
     webBrowserPanel = new JPanel(new BorderLayout());
     webBrowser = new JWebBrowser();
     webBrowser.navigate(url);
     webBrowser.setButtonBarVisible(false);
     webBrowser.setMenuBarVisible(false);
     webBrowser.setBarsVisible(false);
     webBrowser.setStatusBarVisible(false);
     webBrowserPanel.add(webBrowser, BorderLayout.CENTER);
     add(webBrowserPanel, BorderLayout.CENTER);
   }

   public static void main(String[] args) {
    final String url = "http://";
    final String title = "電信營業廳繳費終端";
       UIUtils.setPreferredLookAndFeel();
       NativeInterface.open();

       SwingUtilities.invokeLater(new Runnable() {
       public void run() {
        JFrame frame = new JFrame(title);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(new EagleBrowser(url), BorderLayout.CENTER);
        frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
        frame.setLocationByPlatform(true);
        //frame.setUndecorated(true);
        frame.setVisible(true);
       }
     });
     NativeInterface.runEventPump();
   }
