Why JSTL number format value does not support runtime expressions?

Question

I have this code:

<         


        

Answer 1

Ensure that you are using the correct @ taglib directive. Replace:

<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt"%>

with:

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

The /jsp makes the difference.
