You can extend JFrame to have a JTextPane with scrollbars. Then use JTextPane's setPage() method to point to the html file.
Below code snippet will provide you the clues,

JTextPane tp = new JTextPane();
  JScrollPane js = new JScrollPane();
  js.getViewport().add(tp);
  JFrame jf = new JFrame();
  jf.getContentPane().add(js);
  jf.pack();
  jf.setSize(400,500);
  jf.setVisible(true); 
  
  try {
    	File f = new File("test.html");
	URL url = f.toURL();
    tp.setPage(url);
    } 
  catch (Exception e) {
    e.printStackTrace();
    }

It is compliant to HTML 3.2 only.

Or you can also use internal browsers like Lobo

Or if you are using jdk6 than you also you the Desktop APIs to launch browser

Hello shashikant.v,

If you what you need is to open the html page from your help menu app, you can use the Desktop API in SE 6... like this:

Desktop desktop = null;
		URI uri = null;
		
		if (Desktop.isDesktopSupported()){
			desktop = Desktop.getDesktop();
		}
		if (desktop.isSupported(Desktop.Action.BROWSE)){
			try {
				uri = new URI("http://www.daniweb.com/");
				desktop.browse(uri);
			} catch (URISyntaxException e) {
				e.printStackTrace();
			} catch (IOException e) {
				e.printStackTrace();
			}
			
		}
