Re: c:empty doesnt work on sets

Hi Martyn, 

I tested your code as follows:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

  <jsp:useBean id="mySet" scope="page" class="java.util.HashSet" />

  <c:if test="${!empty mySet}">
      NOT EMPTY
  </c:if>

  <c:if test="${empty mySet}">
      EMPTY
  </c:if>


The above code does not print NOT EMPTY. It only prints EMPTY, on JSTL1.1 + Tomcat 5.5 (Servlet2.4 web.xml)

All I can think of is that your JSTL1.1 settings might be a little incorrect. 

You may want to check the taglib directives, web.xml version (if you're using Servlet 2.4), the correct JAR files.

Hi All

I have a question concerning the c:empty tag. I'm sure this question has 
been asked before but I cant find an answer anywhere.

If I test a set if it's not empty by coding like this:

<c:if test="${!empty mySet}">
    NOT EMPTY
</c:if>

I see NOT EMPTY printed on the screen if mySet is empty. If I'm not 
mistaken this should be fixed in Standard-1.1 Taglib.

Any help would be appreciated.

Martyn
