I almost guessed that was the reason you wanted to create a specifik
tag.
Could it be that you try to iterate over a Map? Afaik a Map value is
accessed in a fashion different from Lists. You must reference the
values in the Map on the form ${var.value} where a List value is
accessed just as ${var}. From there on the get for example the
Person.getName() you should be able to say ${var.value.name}.

Example 1:
<c:forEach items="${myMap}" var="m">
Key: ${m.key} Value: ${m.value}
</c:forEach>
<c:forEach items="${myList}" var="l">
Value: ${l}
</c:forEach>
------------------------------------------------------------------
Example 2 (tag):
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root
xmlns:jsp="http://java.sun.com/JSP/Page";
xmlns:c="http://java.sun.com/jsp/jstl/core";
xmlns:tags="urn:jsptagdir:/WEB-INF/tags"
version="2.0">
<jsp:directive.attribute name="objects"
type="java.lang.Object"
required="true"/>
<!-- Start the tag rendering -->
<c:forEach items="${objects}" var="item">
Value: ${item}
</c:forEach>
</jsp:root>
