"None of tags will work .They will just print out ${amount} and
{fn.length(pmts)} instead of values"
I assume you're putting them within a <c:out...> and not just expecting
${amount} to print something in the JSP.

Subject: RE: Urgent: urgent jstl foreach tag is not working
Hi,
I am sorry for pestering you. But I need your help desperately. Please
let
me clarify with you about my JSTL setup.
1.Downloaded jakarta-taglibs-standard-1.1.2
2.Copied jstl.jsr,standard.jar to web-inf/lib
3.Copied tlds to web-inf/tlds folder
4.Added taglibs to web.xml as below
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/tlds/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/functions</taglib-uri>
<taglib-location>/WEB-INF/tlds/fn.tld</taglib-location>
</taglib>
If I use below tag uris
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions"; prefix="fn"%>
None of tags will work .They will just print out ${amount} and
{fn.length(pmts)} instead of values
And if I use
<%@ taglib uri="http://java.sun.com/jstl/core"; prefix="c"%>
<%@ taglib uri="http://java.sun.com/jstl/functions"; prefix="fn"%>
Alteast core tags are working and prints values and function tags they
just
print {fn.length(pmts)}.
Can anyone let me know if I am missing anything in my configuration?
Thanks
Suneetha

That's because you're using JSTL 1.0 URIs but trying to use JSTL 1.1
functionality. If you correct your URIs, it should work (assuming you
actually have a JSTL 1.1 implementation).
