JSTL is probably a better option that struts logic tags, as you gain
the benefits of containers being optimised for c:if and
c:choose/c:when while not needing scriptlet code. logic tags where
written before jstl was kicking around.
<c:if test="${empty myvar}">
My variable exists
</c:if>
rather than
<%
if(null != myvar && !"".equals(myvar)) {
%>
My variable exists
<%
}
%>
If your container supports jstl then I'd choose it over scriptlets any
day, and in theory containers are optimised for it.
