   ReadableByteChannel rbc = Channels.newChannel(website.openStream());
   FileOutputStream fos = new FileOutputStream("information.html");
   fos.getChannel().transferFrom(rbc, 0, 1 << 24);

 

and this my java page i want it to work in.

 

   package layout;

   /*
 * TabDemo.java
 */

   import java.awt.*;
   import javax.swing.*;

   public class TabDemo {
   final static String HOMEBUTTONPANEL = "Home";
   final static String MAINBUTTONPANEL = "Main Plugins";
   final static String ECONOMYBUTTONPANEL = "Economy Plugins";
   final static String FUNBUTTONPANEL = "Fun Plugins";
   final static String PERMBUTTONPANEL = "Permissions Plugins";
   final static String WORLDMODBUTTONPANEL = "World Modifiers";
   final static int extraWindowWidth = 600;
   final static int extraWindowHeight = 600;

   public void addComponentToPane(Container pane) {
   JTabbedPane tabbedPane = new JTabbedPane();

   //Create the "cards".
   JPanel card1 = new JPanel() {
   //Make the panel wider than it really needs, so
   //the window's wide enough for the tabs to stay
   //in one row.
   public Dimension getPreferredSize() {
   Dimension size = super.getPreferredSize();
   size.width += extraWindowWidth;
   size.height += extraWindowHeight;
   return size;
   }
   };



   JPanel card2 = new JPanel();

   card2.add(new JButton("Chest Shop"));
   card2.add(new JButton("Essentials"));
   card2.add(new JButton("Factions"));
   card2.add(new JButton("GroupManager"));
   card2.add(new JButton("Iconomy"));
   card2.add(new JButton("Kingdoms"));
   card2.add(new JButton("PermissionsEx"));
   //Breakline here
   card2.add(new JButton("Towny"));
   card2.add(new JButton("World Border"));
   card2.add(new JButton("World Edit"));
   card2.add(new JButton("World Guard"));


   tabbedPane.addTab(HOMEBUTTONPANEL, card1);
   tabbedPane.addTab(MAINBUTTONPANEL, card2);

   pane.add(tabbedPane, BorderLayout.CENTER);
   }

   /**
  * Create the GUI and show it. For thread safety,
  * this method should be invoked from the
  * event dispatch thread.
  */
   private static void createAndShowGUI() {
   //Create and set up the window.
   JFrame frame = new JFrame("Minecraft Server Plugin Downloader");
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

   //Create and set up the content pane.
   TabDemo demo = new TabDemo();
   demo.addComponentToPane(frame.getContentPane());

   //Display the window.
   frame.pack();
   frame.setVisible(true);
   }

   public static void main(String[] args) {
   /* Use an appropriate Look and Feel */
   try {
   //UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
   UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");
   } catch (UnsupportedLookAndFeelException ex) {
   ex.printStackTrace();
   } catch (IllegalAccessException ex) {
   ex.printStackTrace();
   } catch (InstantiationException ex) {
   ex.printStackTrace();
   } catch (ClassNotFoundException ex) {
   ex.printStackTrace();
   }
   /* Turn off metal's use of bold fonts */
   UIManager.put("swing.boldMetal", Boolean.FALSE);

   //Schedule a job for the event dispatch thread:
   //creating and showing this application's GUI.
   javax.swing.SwingUtilities.invokeLater(new Runnable() {
   public void run() {
   createAndShowGUI();
   }
   });
   }
   }
