I am working on a servlet generating pdf using fop-0.20.5rc2.
It uses a Templates object "stylesheet", like this:
//Setup XSLT
Transformer transformer = styleSheet.newTransformer();
Iterator entries = parameters.entrySet().iterator();
while (entries.hasNext()) {
Map.Entry entry = (Map.Entry) entries.next();
transformer.setParameter((String) entry.getKey(), entry.getValue());
}
//Resulting SAX events (the generated FO) must be piped through to FOP
Result res = new SAXResult(driver.getContentHandler());
//Start XSLT transformation and FOP processing
transformer.transform(xml, res);
When I run this from the IDE on my PC, it works. Under Tomcat on a unix
box, it works for some style sheets, but for some which work on the
PC I get an error, which I find very confusing. See attached file.
First FOP reports the pdf rendered with no problems, then Xalan throws
an exception.
Do any of you know what might be causing this?
The unix box uses j2sdk1_3_1_01 and xalan-2.0.0, the pc uses j2sdk1_3_1_07
Here is a short stylesheet that causes the error:

I have not been able to come up with a search string that finds anything
promising in the list archives or
on Google.
