帮我修改下不听话的代码

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
public class applet extends JFrame
{  JLabel l1;
  public applet()
  {
      setSize(200,200);
      l1=new JLabel();
      l1.setToolTipText("sohu");
      l1.setDisplayedMnemonic('0');
      l1.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
      l1.setForeground(Color.red);
      l1.setText("<html><body><a href=http://www.sohu.com>sohu</a></body></html>");
      l1.setBounds(new Rectangle(50,50,80,30));
      l1.addMouseListener(new java.awt.event.MouseAdapter()
               {
                 public void mouseReleased(MouseEvent e)
                 {
                   try
                   {
                    Runtime.getRuntime().exec("cmd/c start http://www.sohu.com");
                   }
                   catch(Exception e1)
                   {
                   
                   }
                 }
               });
      add(l1,null);
      setLayout(null);
      setVisible(true);
  
  }
   public static void main(String[] args)
     {
      new applet();
     }
   
   
}
//我的希望是打开连接www.sohu.com的网页，怎么就是连接不上，忘高手指点
