[jboss-user] [JBoss Portal] - using jstl 1.1.2 problem

[k3nnymusic]

I am using jboss portal 2.4.2 and jboss as 4.0.5 GA.
I depoloyed my portlet with jstl, and its sucessfull, but i have got errors when I rendering it.
My web.xml configuration:
<web-app>
  | 	<taglib>
  | 	   	<taglib-uri>/tags/jstl-c</taglib-uri>
  | 	   	<taglib-location>/WEB-INF/tld/c.tld</taglib-location>
  | 	</taglib>
  | </web-app>

jsp tags:
<%@ taglib uri="/tags/jstl-c" prefix="c"%>
  | <%@ page isELIgnored="false" %>

and I am added jstl.jar and standard.jar to my war package.
Should I configure something else? Might be I using wrong version of jstl?
This is error:
