Frank, I believe I have solved at least the first of your problems, from
your note 03/17/2002 "problem with apply-templates in content of
with-param".
The problem had to do with calling a variable within an RTF that is being
passed in a xsl:with-param. The first RTF screwed up the access of the
frame for the second variable ref. Inside an xsl:with-param is a tricky
situation, because we are accessing variables from behind the frame that we
are defining.
Anyway, I'm guessing, but do not know, that this will also fix your
"Stylesheet Reuse NullPointerException" bug. HOWEVER, it's a little
surprising that any of this would be related to stylesheet reuse, so maybe
not.
Can you run off the current CVS, or do you need me to send you a jar to try
out?

Thanks, Scott. I'll look forward to the fix.

Not sure about Hugo's code. Here's mine:
public static void exampleTransformerReuse(Vector sources, String xslID)
throws TransformerException, TransformerConfigurationException
{
TransformerFactory tfactory = TransformerFactory.newInstance();
Transformer transformer = tfactory.newTransformer(new
StreamSource(xslID));
for (Enumeration e=sources.elements(); e.hasMoreElements(); )
{
String sourceID = (String)e.nextElement();
System.out.println("\n=========" + sourceID + "\n");
transformer.transform( new StreamSource(baseDir + sourceID),
new StreamResult(destDir + sourceID));
}
}
