If you're going to use JSTL, you'll probably want to switch to the Struts-EL
tags so you can use expressions with them as well.
The form is a bean, so you can just use the name you configured in
struts-config.xml.
<c:out value="${someForm.elementIndex}"/>
You don't really need the <c:set> in your example above, just use the form
element directly:
<c:if test="${!empty myBean.list[someForm.elementIndex]}">
but it will work either way.
If you're using a dynamic form, you'll need to go through the map to get at
the properties.
