JSTL 1.1 uri should be "core_rt" ?

[Vince Hon]

I cannot run JSTL smooth !

I have put the jtsl.jar and standard.jar from tomcat 5 to the webapp\lib according to HSB. And my web.xml is version 2.4:

<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/web-app_2_4.xsd" version="2.4">

In jsp, I put this:

 
<%@ page isErrorPage="true" %>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
 
<c:if test="${exception != null}">
  it is null
</c:if>

When I run, I got the error: According to TLD or attribute driective in tag file, attribute test does not accept any expressions.

After searching on the web, If I changed
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
to
<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c" %>

The JSTL work perfectly. Does any one can explain this ?

Thanks

Vince,

Make sure if you are using Tomcat 5.x the uri has the "jsp" in it. Example:-

 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>;

thanks Sadana !

I just realized that I use to old version of URI :
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

The correct one should be:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
