fn:length cannot be found: org.apache.taglibs.standard.functions.Functions

I have included tag library in jsp as mentioned below:

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

And I am trying to use it in this code:

<c:when test="${fn:length(training.trainingevents) gt 0 }">

But getting below error

org.apache.jasper.JasperException: The class org.apache.taglibs.standard.functions.Functions specified in TLD for the function fn:length cannot be found: org.apache.taglibs.standard.functions.Functions

Solution

  • Not sure, about the error of jstl tag library, but I could solve the problem by using below code,

    <c:when test="${not empty training.trainingevents}">
