Why are my JSTL tags not being interpreted in my JSF page?

[Jehan Jaleel]

Hi all,

I have a JSF page (.xhtml extension). In it I have the following..

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:f="http://java.sun.com/jsf/core"
	xmlns:c="http://java.sun.com/jstl/core"
	xmlns:ui="http://java.sun.com/jsf/facelets"
	xmlns:p="http://primefaces.org/ui" template="/templates/template.xhtml">

 There is more code in between these snippets but I did not include because it is not relevant.                     
             <c:choose>
							<c:when test="${current.totalAdviceAmtAgntStlCur > 0}">
							<h:outputText value="Invoice" />
							</c:when>
							<c:otherwise>
								<h:outputText value="Credit Memo" />
							</c:otherwise>
						</c:choose>

But this JSTL code is not being interpreted. When the page loads it shows both Invoice and Credit Memo and I do view source I see "<c:choose" in my source. I made sure JSTL 1.2 jar is there in my WEB INF/lib.

What else could be missing? Is JSTL not supported on xhtml pages?

Thanks.>

Please be sure to ask JSF questions in the JSF forum. I have moved this post there for you.

Does this not do the trick for JSTL taglib directory..

<ui:composition
xmlns:c="http://java.sun.com/jstl/core">

I figuered it out. Seems JSTL tags do not work inside JSF datatable. When I changed to the following it worked...

<h:outputText value="Invoice"
							rendered="#{current.totalAdviceAmtAgntStlCur gt 0}" />

						<h:outputText value="Credit Memo"
							rendered="#{current.totalAdviceAmtAgntStlCur lt 0}" />

There is practically no reason for ever using JSTL in JSF pages, because the same functions are available via native JSF tags - which, unlike JSTL - are aware of the JSF environment.
