What I'd like to do is... <c:if test="${services.size() gt 1}"> <!-- markup... --> </c:if> But you can't invoke methods on Java objects in EL (I think this is perhaps the 364823782 time I've regr...

I have a navigation bar and, for some pages, a sub-navigation bar as well. I'd like to make this a module so I can easily import the navigation bars on each page. Easy enough to simply put the code in a JSP file and call: <%@include file="/WEB-INF/jsp/includes/sub_nav_bar.jsp"%> the only issue is the links and their labels change de...
