Are you sure you don't have something else which causes the parser
or the transformer to throw a NPE?
With the following code
try {
Driver driver=new Driver();
driver.setRenderer(Driver.RENDERER_PDF);
driver.setOutputStream(...);
Transformer transformer=TransformerFactory.newInstance()
.newTransformer(new StreamSource(new File("stuff.xsl")));
transformer.transform(new StreamSource(new File("stuff.xml")),
new SAXSource(driver.getContentHandler()));
}
catch( Exception e) {
System.out.println(e.getMessage());
}
I get the "page-sequence must be..." message without a problem, and
the caught Exception is a TransformerException.
