java.net.MalformedURLException from XMLVersionDetector.determineDocVersion?

I'm having problems parsing an xml config doc of an
open source scheduling tool (Quartz).  The document
(below)is well formed and valid. I'm able to
successfully validate it using and xml editor (Stylus
Studio) and with Xerces in a stand-alone command line
parsing utility.  However, when the document is parsed
during server startup (Tomcat v5.0.25) I get the
following exception:

What is the root cause for this failure?  What is it
that Xerces is trying to do that it can't?

Re: java.net.MalformedURLException from XMLVersionDetector.determineDocVersion?

Posted by Jon Wilmoth <jo...@yahoo.com>.
Thank you!  That was the key I needed.  It turns out
the file was being deployed to the web-app's WEB-INF
directory.  The quartz code that parses the document
uses ClassLoader.getResourceAsStream to get the
document.  Unfortunately the servlet container class
loader didn't wasn't reading the WEB-INF directory,
but rather the WEB-INF/classes & WEB-INF/lib
directory.  Moving the deployment location allowed the
classloader to find the doc and parse it.

Thanks again!

Hello Jon,
