Weird. I observe the opposite effect:
- ---------------
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %>
<c:set var="foo" scope="request" >FOO-VALUE</c:set>
<p>
Using JSTL: <c:out value="${foo}" />
</p>
<p>
Direct-to-request using JSTL: <c:out value="${requestScope.foo}" />
</p>
<p>
Using direct request fetch <%= request.getAttribute("foo") %>
</p>
- ------------
The above emits the following for me:
- ---------------
Using JSTL: ${foo}
Direct-to-request using JSTL: ${requestScope.foo}
Using direct request fetch FOO-VALUE
- ---------------
Can you get the JSTL to print your values using <c:out>?
