java - Passing parameters between jsp and xsl -

i have problem between jsp page , xsl, want pass parameter between jsp , xsl never set in xsl.

jsp page ;

<%@ page language="java" contenttype="text/html; charset=iso-8859-1"     pageencoding="iso-8859-1"%> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <%@ taglib uri="http://java.sun.com/jsp/jstl/xml" prefix="x"%> <%!     private string getval(string param, httpservletrequest request) {         return request.getparameter("fname");     } %> <%     string num = getval("value", request); %>  <div id="section" class="col-xs-10 col-sm-10 col-md-8">             <c:import url="/monxml.xml" var="inputdoc" />              <c:import url="/viewannonce.xsl" var="stylesheet" />             <x:transform xml="${inputdoc}" xslt="${stylesheet}" >                  <x:param name="numannonce" value="${num}"/>             </x:transform>          </div> 

xsl :

<xsl:stylesheet version="1.0"     xmlns:xsl="http://www.w3.org/1999/xsl/transform">     <xsl:output method="html" encoding="utf-8"         doctype-public="-//w3c//dtd xhtml 1.0 transitional//en"         doctype-system="http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd" />    <xsl:param name="numannonce"/>   <xsl:template match="/">     <xsl:template match="/">         <!-- creation de la liste des annonces -->         <xsl:for-each select=".//annonce[attribute::id=$numannonce]">             <div id="article" class="row"></div>         </xsl:for-each>  </xsl:template> 

`

the getval("value", request); return correct value.

thanks.

you have declared num variable using jsp scriptlet, don't think can access ${num} , try accessing scriptlet :

<x:param name="numannonce" value="<%=num%>"/>
