If you can use JSTL1.1, you can use the fn: Function-Library
to query the length of properties
http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html
     

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.
   

Here's a good summary of the fn: library including an example using
fn:length:
http://java.sun.com/webservices/docs/1.3/tutorial/doc/JSTL8.html#wp84680

 

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.

HTH,
   Yann
