Kris,
Thanks for your tip. You lead me to the answer. Here is what works:
<c:set var="person" value="${requestScope.personForm}"/>
<c:set var="nestedProp" value="name.firstName"/>
<c:set var="val" value="${nestedProp}" property="${person}" />
Now, we can all stand around and scratch our heads and say "Duh! Why didn't I
think of that?" Setting the person as the property tells JSTL to use person
as a bean and allows it to do normal nested queries on nestedProp. Oh man do
I feel like a dummy.
