Empty check is not working in JSP

I have my forEach in my code.

I try to check is the teams are empty, if that is true, result should be other than false.

<tbody>
<c:forEach items="${teams}" var="team">
    <c:choose>
        <c:when test="${not empty teams}">
            var1 is NOT empty or null.
        </c:when>
        <c:otherwise>
            var is empty!
        </c:otherwise>
    </c:choose>
</c:forEach>
</tbody>

The problem is with otherwise or if... empty teams.

It is'not working.

That string is not showing on a website.

Try using the fn function,

<tbody>
<c:forEach items="${teams}" var="team">

  <c:choose>
    <c:when test="${fn:length(teams) > 0}">
        var1 is NOT empty or null.
    </c:when>
    <c:otherwise>
        var is empty!
    </c:otherwise>
  </c:choose>
</c:forEach>
</tbody>

You have to include <%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%> for this.
