JSTL problems

I'm running WSAD 5.1.0 and deploying to the Portal 5.0 test
environment. I've configured my project so it knows where to go to get
the JSTL tlds. But if I run something like this:


<c:forEach var="num" items="1,2,3,4" >
<c:out value='${num}' />
</c:forEach>


or this:


<c:forEach var="num" items="1,2,3,4" >
${num}
</c:forEach>


I get this:


${num} ${num} ${num} ${num}


Obviously Websphere is finding the taglibs and the associated classes,
because I get the right number of iterations. But something is messed
up, because the variable doesn't resolve. Has anyone else had this
problem? Did you solve it?
