My requirement is really a bit different. I have an expression, which
returns a List, the size of which I would like to display. I.e. I have
${myController.activitiesForResource}, which returns a list.
If I try <c:out
value="${fn:length(${myController.activitiesForResource})}"/> I get an error
saying "EL expressions are not supported". Any ideas?
Thanks,
Marius

Hi Marius,
Check out the fn:length() function, this is what you are looking for.
size() is a method and you cannot call methods directly from JSTL (only
getters and setters), but the fn taglib provides a function for length
of Collections and strings. See the JSTL 1.1 documentation for more
information, but basically fn:length() is what you are looking for:
<c:out value="${fn:length(myList)}"/>
Hope this helps.
