Maybe this will help you, it works for me with the Sun Java compiler:

public class HTMLDisplayer extends    JPanel
                           implements HyperlinkListener
{
   /**
    * Pane where the HTML document will be displayed
    */
   JEditorPane d_HTMLEditor;


   /**
    * Given the URL to the document, display it.
    *
    * @param url The url where the document is
    */
   public HTMLDisplayer ( URL url )
   {
      super ( new BorderLayout () );
      initialize ( url );
   }

   /**
    * Do the actual initialization
    *
    * @param url URL with the document to be displayed
    */
   private void initialize ( URL url )
   {
      try {
         d_HTMLEditor = new JEditorPane ( url );
      } catch ( IOException e ) {
         JOptionPane.showMessageDialog ( this,
                                         "File read error!",
                                         "Open",
                                         JOptionPane.ERROR_MESSAGE );
      }
      d_HTMLEditor.setEditable ( false );
      d_HTMLEditor.addHyperlinkListener ( this );
      JScrollPane scroller = new JScrollPane ( d_HTMLEditor );
      scroller.setBorder ( new BevelBorder ( BevelBorder.LOWERED ) );
      add ( scroller, BorderLayout.CENTER );
   }

   /**
    * Notification of a change relative to a hyperlink.
    */
   public void hyperlinkUpdate(HyperlinkEvent e)
   {
      if ( e.getEventType() == HyperlinkEvent.EventType.ACTIVATED )
         try {
            d_HTMLEditor.setPage ( e.getURL () );
         } catch ( IOException x ) {
            JOptionPane.showMessageDialog ( this,
                                            "File read error!",
                                            "Open",
                                            JOptionPane.ERROR_MESSAGE );
         }
   }

}

However, this has a problem following hyperlinks in the same document.
Apparently you need to include the document name as part of the HREF
link, otherwise the call to setPage ( e.getURL () ) won't work. In
other words, in your HTML source you need to:

<A HREF="filename.html#refname">The link</A>

Hope that helps.
