Subject Re: Taglibs ; error in a JSP using expression langluage
Date Tue, 08 Aug 2006 11:43:11 GMT
which version of tomcat are you using?

is Expression Language enabled? as it looks like it's passing the ${0}
variable as a string rather than evaluating it.

Try setting the following attribute in your JSP 'page' directive.

<%@ page ... isELIgnored="false" %>
