I agree with Shawn that complex code should go in some other type of
component, but for simple sorts I sometimes use this trick:
<%-- Create a TreeMap: it sorts its keys automatically --%>
<jsp:useBean id="sorted" class="java.util.TreeMap" />
<%-- Add the values to be sorted as keys in the TreeMap --%>
<c:set target="${sorted}" property="z" value="" />
<c:set target="${sorted}" property="b" value="" />
<c:set target="${sorted}" property="x" value="" />
<%-- Use the sorted keys --%>
<c:forEach items="${sorted}" var="c">
<c:out value="${c.key}" />
</c:forEach>
