Re: Mixing JSTL & JSF

[Matthias Wessendorf <ma...@matthias-wessendorf.de>]

Hi,

<c:forEach/> does not work with JSF
but some other JSTL tags may work
(eg <jsp:include/> or <c:import/>)

See spec of JSF and/or this article:
http://www.onjava.com/pub/a/onjava/2004/06/09/jsf.html

BTW. Oracle's ADF Faces (a set of JSF components)
ship such a "forEach" component.

HTH,
Matthias
