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

This is a whitespace issue.

JSP must dutifully respect whitespace in your
page. The result of your XSLT processor call
is likely producing an XML declaration which
(due to whitespace between your <%@ page %>
lines and the <% %> surrounding your java
end up producing a result like:

+----------
|
|<?xml version="1.0" ?>

It's illegal to have the XML declaration be
anywhere except the *very* beginning of
the file!

Try something like:

<%@ 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));

 %>

to see if it helps.
