I used Tomcat 5.16 and jakarta jstl 1.1 and when i use the functions it says not implemented. Did i make a mistake or is it normal ? Tomcat says : An error occurred while parsing custom action attribute "value" with value "${fn:length(ligne)}": org.apache.taglibs.standard.lang.jstl.parser.ParseException: EL functions are not supported.

Showing messages 1 through 3 of 3.

  Most likely, you're using the JSTL 1.0 URIs in the taglib directive instead of the JSTL 1.1 URIs, e.g.,
  
  http://java.sun.com/jstl/core
  
  instead of
  
  http://java.sun.com/jsp/jstl/core
  
  The JSTL 1.0 libraries handles EL expressions by themselves, so to the JSP 2.0 container, they look like custom actions that don't accept EL values.

  Hi. You probably don't have your web app set to be a servlet 2.4 web app.
  
  Your wep app declaration in your web.xml should look like this:
  
  <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">
