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

Thanks for helping everyone. I realised it was a stupid mistake from my side..

Instead of

<fmt:formatDate value="date" var="${eventDate}" />

It should be

<fmt:formatDate type="date" value="${calendarEntry.date}"

Answer 2

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" %>

Answer 3

<fmt:formatDate value="date" var="${eventDate}" />

Switch value and var.

<fmt:formatDate var="date" value="${eventDate}" />

Answer 4

You should change attribute var to pattern,you can try as below:

<fmt:formatDate value="${eventDate}" pattern="yyyy-MM-dd HH:mm:ss"/>

You can change the value of pattern based on your own,and it has nothing to do with the order of value and pattern

In netbeans it does not create a web.xml file automatically now.(previously in j2ee it was created. it is optional for some cases.I face the same issue with the jstl remove attribute and after I created the web.xml file the issue was gone.but corrected one is a new project

Answer 6

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

Change the above to:

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

I had similar issue. I changed Tomcat version to- apache-tomcat-7.0.39 instead of -apache-tomcat-7.0.54 from SERVER- Runtime Environment
