My next guess was going to be one thing mentioned on the page Murray links to below. Regardless of whether you are using Tomcat 5, JSTL 1.1 and JSP 2.0... if your web.xml doesn't say it's a servlet 2.4 app it will revert to Servlet 2.3/JSP 1.2 (and trying to use JSTL 1.1 with JSP 1.2 probably introduces many other problems...). As the page says, make sure your <webapp> element starts 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"> Otherwise the container will assume the servlet 2.3 spec and EL will not be allowed outside of JSTL (1.0) tags. The fn:length() function I originally mentioned is part of JSTL 1.1 anyway so it sounds like you just need to make sure everything is configured for the current specs and you should be good. Hope that will fix it up for you. -Christian Murray Steele wrote: > Perhaps this page might provide the solution? > > http://www.oreillynet.com/cs/user/view/cs_msg/32931 > > Wrong taglib uri's or wrong webapp specification in your web.xml. > > Muz > > On 2 Aug 2005, at 14:32, Marius Botha wrote: > > > You know your stuff hey :) > > > > I believe I do use Tomcat 5 (running inside JBoss 3.2) and as a result > > have > > their JSTL (looks like 1.1) and JSP-2.0.jar.
