RE: can XML-XSL do what Lisp and s-expressions do?

["Paul Beer" <paul.beer@xxxxxxxxxxxx>]

does anyone have any idea why this jsp code would produce the error dump
below ?


<%@ page import="org.apache.xalan.xslt.XSLTProcessor"%>
<%@ page import="org.apache.xalan.xslt.XSLTResultTarget"%>
<%@ page import="org.apache.xalan.xslt.XSLTInputSource"%>
<%@ page import="org.apache.xalan.xslt.XSLTProcessorFactory" %>
<%@ page import="org.xml.sax.SAXException"%>

<%

    XSLTProcessor processor = XSLTProcessorFactory.getProcessor();
    processor.process(new XSLTInputSource("invoice.xml"),
                      new XSLTInputSource("invoice.xsl"),
                      new XSLTResultTarget(System.out));
