GWT 1.6 Jetty problem?

[Paul van Hoven]

I know that this question doesn't refer directly to GWT but i think it
refers to the Jetty server bundled with GWT 1.6. After making a
correction in the web.xml file according to this dicussion (
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/fa738eeca9da6daf/37390477a05d32ca?lnk=gst&q=expression+language#37390477a05d32ca
) i now got a new problem.
By using
"<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>"
the EL
"${params.value}"
works but
"<c:out value="${params.value}"/>"
does not.

I get the following error message by jetty:
"According to TLD or attribute directive in tag file, attribute value
does not accept any expressions"

Has this something to do with the jetty server?
