Re: [docbook-apps] Advice on Java DocBook DOMSource() to PDF

["Don Adams" <dga@sgi.com>]

Thanks, Bob.  Your analysis has lead me to
find this bug description:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4459167

Just for anyone following or searching on
this thread, I tried the following in
my URIResolver:

URL myURL = this.getClass().getResource("/xsl/xhtml/");
streamSource.setSystemId(myURL.toString());

But, I got "(Access is denied)" errors.
