Make sure you include:
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions"; prefix="fn" %>

I use bean:size. I don't know if there is a JSTL equivalent. Seems odd 
that there wouldn't be one, but I can't find one in my JSTL reference.

Obtaining size of java.util.Collection through Struts/JSTL

[Greg Pelly]

What is the prefered way to obtain the size of elements that implement the
Collection interface, such as a Vector?  I would like something like:

 elements exist in
this Vector!

But since the method is called "size()" and not "getSize()," Struts can't
handle it.  Right now I am using scriptlets:
<%
  java.util.Vector v = request.getAttribute("myVector");
%>

...and later...

<%= v.size() %> elements exist in this Vector!

Any advice?
