[docbook-apps] Javahelp browser shows no contents

["Peter Desjardins" <pdesjardins at supplyscape dot com>]

I generated Javahelp files from my Docbook project using version 1.68.1
of the Docbook XSL stylesheets and Saxon.  I installed JavaHelp version
2.0.  The OS is Windows XP.

When I try to open the help file, I see the messages pasted below and
the JavaHelp browser shows no contents (but does display the document
title at the top of the browser window).

Am I misusing Javahelp?  Can anyone tell me what problem this message
might be pointing to?  The source Docbook files are valid and I can
generate HTML help successfully.
