Question

Trying to use JSTL but have the following problem:

Index.xhtml page:

Answer 1

I could solve the problem with adding xmlns:fmt="http://java.sun.com/jsp/jstl/fmt" in my xhtml file.

OR

declaring this in my web.xml, and copying the c.tld in /WEB-INF/jsp from my application:

<jsp-config> 
        <taglib> 
               <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri> 
               <taglib-location>/WEB-INF/jsp/c.tld</taglib-location> 
        </taglib> 
</jsp-config>

Warning: xmlns:c="http://java.sun.com/jstl/core" throws exception, collected in my h:messages Tag

Answer 2

Seems that:

The solution is to remove the /jsp from the jstl namespace:

xmlns:c="http://java.sun.com/jstl/core"
