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.

    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.

      <web-app xmlns="" xmlns:xsi="" xsi:schemaLocation="" version="2.4">
