Subject Getting mad with jsp 2.0 <jsp:directive.include file="file_to_include.jsp"/>
Date Wed, 30 Jun 2004 08:10:30 GMT
Hello, hope somebody knows whats going on here...

I have a main.jsp with the following start..

<?xml version="1.0" encoding="utf-8"?>
<jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page" 
	xmlns="http://www.w3.org/1999/xhtml"
	xmlns:c="http://java.sun.com/jsp/jstl/core"
	xmlns:fn="http://java.sun.com/jsp/jstl/functions"
	xmlns:html="/WEB-INF/struts-html-el.tld"
	xmlns:am="/WEB-INF/AccessManager2.tld"
	xmlns:bean="/WEB-INF/struts-bean-el.tld">
<jsp:output doctype-root-element="html"
         doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"
 
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" />
<jsp:directive.page contentType="text/html; charset=utf-8" language="java"
/>
<html:html locale="true" xhtml="true"> 
<head>
  <html:base/>
  <title><bean:message key="login.title"/></title>
  <c:url value="/css/style.css" var="link">
	</c:url>
  <link rel="stylesheet" href="${fn:escapeXml(link)}" type="text/css"/>
  	
		<jsp:directive.include file="/jsp/ascript.jsp"/>
	
</head>
....

the /jsp/ascript.jsp looks like that:

<script type="text/javascript">
    var newWindow;

    function openInsertWindow()
    {
    	<c:url value="/messdatenPreloadAction.do" var="link">
    		<c:param name="operation" value="insertDataset"/>
		</c:url>
      newWindow =
window.open("${fn:escapeXml(link)}","_blank","resizable=yes,scrollbars=yes,w
idth=800,height=600,status=yes");
    }
...

ok, now the problem:
when i call the jsp tomcat (jasper) throws the following exception:

org.apache.jasper.JasperException: /jsp/ascript.jsp(9,33) The attribute
prefix fn does not correspond to any imported tag library

I thought ok, and added the same declaration to the /jsp/ascript.jsp include
file like in the main.jsp:

<?xml version="1.0" encoding="utf-8"?>
<jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page" 
	xmlns="http://www.w3.org/1999/xhtml"
	xmlns:c="http://java.sun.com/jsp/jstl/core"
	xmlns:fn="http://java.sun.com/jsp/jstl/functions"
	xmlns:html="/WEB-INF/struts-html-el.tld"
	xmlns:am="/WEB-INF/AccessManager2.tld"
	xmlns:bean="/WEB-INF/struts-bean-el.tld">
<script type="text/javascript">
    var newWindow;

    function openInsertWindow()
    {
    	<c:url value="/messdatenPreloadAction.do" var="link">
    		<c:param name="operation" value="insertDataset"/>
		</c:url>
      newWindow =
window.open("${fn:escapeXml(link)}","_blank","resizable=yes,scrollbars=yes,w
idth=800,height=600,status=yes");
    }
...


but then i got the exception:

org.apache.jasper.JasperException: <h3>Validation error messages from
TagLibraryValidator for c</h3><p>null: 
org.xml.sax.SAXParseException: Attribute "bean" bound to namespace
"http://www.w3.org/2000/xmlns/" was already 
specified for element "jsp:root".</p>

ok, this seems to be logical to me, because it is alredy declared in
main.jsp.

What can i do to fix this, to get the taglib known in the include but not
double import it???

thanks in advance
