Display collection size with jstl

[Linus Nikander <li...@nikander.net>]

How do I output the size of a collection whilst NOT in a loop ?

I've tried all the

<c:out value="collectionName.size" />
<c:out value="collectionName.length" />

variations I can think of but it doesn't seem to work.

Do I have to use a loop-structure to get at the size ? or do I have to bind
the collection to a page-variable before I can get the size ? Or is there a
syntax for getting it directly ?

The variable I'm trying to access is in session-scope

There is not a way to do it with JSTL 1.0 -- there is a way using the 
function tag lib in JSTL 1.1. If you are using Struts ;) use the 
<bean:size> tag to create a page-scoped variable which can then use.

Hi Robert!

My news-server doesn't give me access to the JTSL list unfortunately. Since
many Struts developers use JSTL for presentation I thougt it'd be the proper
place to ask. Thank you for your answer anyhow.

Linus, this question belongs on the JSTL mailing list.
The answer can also be found in the JSLT 1.1 (mr) specification
section 15.8. 

<c:out value="${fn:length(collectionName)}"/>
