getSystemResource not working in servlet

["Allen,Eva" <al...@oclc.org>]

I'm still having problems with getting xmlrules to work within a Tomcat
servlet container.  I pretty much snagged the code I use from the
xmlrules example that comes with the digester source.  The problem comes
with the getSystemResource call.  I keep getting a null URL.  I finally
named the rules file x.xml and placed it in every directory under
$TOMCAT_HOME and used the following code:
            
URL rulesURL = ClassLoader.getSystemResource("x.xml");

but still the returned URL is null.  This works fine as long as I'm not
running within the Tomcat servlet container.  It also works fine if I do
this instead

            URL rulesURL = null;
            File f = new File("x.xml");
            try {
                rulesURL = f.toURL();
            } catch (MalformedURLException e1) {
                e1.printStackTrace();
            }

but I'd much prefer to do it the "right" way if I could.  Any hints?

This only retrieves resources accessible to the System class loader,
which typically only looks at the $TOMCAT_HOME/bin directory.
