<c:forEach> supports a "varStatus" attribute. The value of that atrribute is a
String that names an instance of javax.servlet.jsp.jstl.core.LoopTagStatus. The
LoopTagStatus instance has nested visibility so that it's only available within
the enclosing <c:forEach> tag. LoopTagStatus exposes a number of properties,
but the one you're probably interested in is "index":
..
<c:forEach var="bean" varStatus="status" items="${entry.value}">
<%-- ${status.index} is the current index --%>
...
</c:forEach>
..
