How to select the first element of a set with JSTL


I managed to do it with the next code but there must be an easier way.

<%@ taglib prefix="c" uri="" %>
<%@ taglib prefix="fn" uri="" %>

<c:if test="${fn:length(attachments) > 0}">
    <c:forEach var="attachment" items="${attachments}" varStatus="loopCount">
        <c:if test="${loopCount.count eq 1}">

Best Solution

You can access individual elements with the array [] operator:

<c:out value="${attachments[0].id}" />

This will work for arrays and lists. It won't work for maps and sets. In that case you must put the key of the element inside the brackets.
