Displaying HTML Page

Question

I am having problems getting my HTML file to actually display. I think I can retrieve the file properly - I'm not getting any errors saying I can't. But when I do retrieve it, I just get a white scrollpane, instead of a scrollpane containing the webpage it should be. The following code is for an object constructor that creates the window that shows the webpage. Any help would be greatly appreciated. Thanks.
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import java.net.URL;
import java.io.IOException;
public class OnlineHelpWindow extends JFrame
     public OnlineHelpWindow()
          super("Online Help");
          Container c = getContentPane();
          JEditorPane editorPane = new JEditorPane();
          editorPane.setEditable(false);
          String s = null;
          try
               String prefix = "file:" + System.getProperty("user.dir") + System.getProperty("file.separator");
               URL url = new URL( prefix + "index.html" );
               System.out.println(url);
          catch (Exception e )
               JOptionPane.showMessageDialog(null, "Unable to load URL: " + s,
                                                            "Unable to load URL",JOptionPane.WARNING_MESSAGE);
          JScrollPane editorScrollPane = new JScrollPane(editorPane);
          editorScrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
          editorScrollPane.setPreferredSize(new Dimension(250, 145));
          editorScrollPane.setMinimumSize(new Dimension(10, 10));
          c.add(editorScrollPane);
          pack();
          show();
}

I think you forgot to put the html page in the editor
try putting the url in the constructor, so the url must be define first.
JEditorPane editorPane = new JEditorPane(url);
It should work
