JSTL1.2 According to TLD or attribute directive in tag file, attribute var does not accept any expressions

Question

I have been searching all over google for an answer and it doesn't work.

I am getting this error:

org.apache.jasper.JasperException: /WEB-INF/pages/calendarEntry.jsp (line: 5, column: 46) According to TLD or attribute directive in tag file, attribute var does not accept any expressions

Here's my jsp file

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main">
    <c:set var="eventDate" value="${calendarEntry.date}"/>
    <h1 class="page-header">Calendar Event on <fmt:formatDate value="date" var="${eventDate}" /></h1>

The error is happening at the last line. fmt

Answer 1

I had a similar problem, and this answer points to basically trying two different taglib declarations. Perhaps try both of them?

Format Date with fmt:formatDate JSP

Switching to the taglib you have declared in your jsp file solved my problem, ironically.

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

vs

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