ejempo if con jstl

Agregar esto al ppio  (para usar fn:length)
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

despues se utiliza asi (notar "gt" en vez de > )

<c:if test="${fn:length(companies) gt 0}">
   <p>It is greater than 0</p>
</c:if>

si solo queremos ver si esta vacio
<c:if test="${empty companies}">

si queremos IF-ELSE
<c:choose> 
  <c:when test="${condition}">
    //this will be executed when condition is true
  </c:when>
  <c:otherwise>
    //this will be executed when condition is false
  </c:otherwise>
</c:choose>
 <c:if test="${enableDemanda != true}">class="disabled"</c:if>
