Passing parameters to XSL using JSTL?

I'm trying to pass a couple parameters back to XSL using the JSTL tag library, but the values are not getting passed.  My code is attached.  

The page loads, but the two values are not being passed.  All I get is a page without any content that would have been filled in the for-each loop.


///// JSP code ////
 
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jstl/xml" %>
<%
	String pageStart = "1";
	String pageLimit = "10";
	
	if (request.getParameter("s") != null)
	{
		pageStart = (String)request.getParameter("s");
	}
	
	if (request.getParameter("l") != null)
		pageLimit = (String)request.getParameter("l");
	
	pageContext.setAttribute("pageStart",pageStart);
	pageContext.setAttribute("pageLimit",pageLimit);
 
%>

The parameters are local to the template for match="/"
and should be global

 <?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" omit-xml-declaration="yes"/>
<xsl:strip-space elements="*"/>
      <xsl:param name="pageStart" />
      <xsl:param name="pageLimit" />
      <xsl:template match="/">
...

should work
