To avoid confusion, it is worth nothing that these functions are part of
the expression language in JSP 2.0 and JSTL 1.1 (both included in JWSDP
1.3), but not JSTL 1.0.

Yann, thanks. That functionality is excellent. This is I guess exactly
what the original poster was asking for.

Here's a good summary of the fn: library including an example using
fn:length:

Hi Yann,
can you give a quick example of the use of this function library, and
perhaps the taglib declaration.
I couldn't find anything in the spec.

If you can use JSTL1.1, you can use the fn: Function-Library
to query the length of properties

Hi Vijay,
you can't use portName.length() because length() is not one of the
javabean specification-compliant methods of String. In fact, I don't
think String has any.
What you can try and this is without testing, is:
<c:set var="portNameLen"><%="TEST".length() %></c:set>
<c:if test="${portNameLen > 15}">
....
</c:if>
