I wanted to embed brower into awt canvas.I wrote 
public class MyBrowser{  
 
   public static void main(String[] args)  
   {  
       final Display display = Display.getDefault();  
 
       Frame frm = new Frame("MyBrowser");  
       Canvas embedded = new Canvas();  
       frm.add(embedded, BorderLayout.CENTER);  
 
       frm.pack();  
 
       final Shell composite = SWT_AWT.new_Shell(display, embedded);  
       composite.setLayout(new FillLayout(SWT.VERTICAL));  
       final Browser browser = installBrowser(composite, "http://www.baidu.com");  
       frm.addWindowListener(new WindowAdapter()  
       {  
           public void windowClosing(WindowEvent e)  
           {  
           e.getWindow().dispose();  
           //composite.dispose();  
//            display.dispose();  
           }  
       });  
 
       JTextField addr = new JTextField(80);  
       addr.addActionListener(new ActionListener()  
       {  
           public void actionPerformed(final ActionEvent e)  
           {  
               display.syncExec(new Runnable()  
               {  
                   public void run()  
                   {  
                       browser.setUrl(((JTextComponent) e.getSource()).getText());  
                   }  
               });  
           }  
       });  
       frm.add(addr, BorderLayout.NORTH);  
 
       frm.setSize(800, 600);  
       frm.setVisible(true);  
       while (frm.isDisplayable())  
           if (!display.readAndDispatch())  
               display.sleep();  
//       display.dispose();  
   }  
 
   public static Browser installBrowser(Composite parent, String homeURL)  
   {  
       Browser browser = new Browser(parent, SWT.EMBEDDED);  
       browser.setUrl(homeURL);  
       return browser;  
   }  
}  
On Windows it works, 
On Linux, the bridge seems to work, but nothing is visible. So I want to know how to make it work on linux. Just swt browser component is OK.When embed it into awt-canvas. it can not work
