How to access the first item in a Collection in a JSP?
I have a Collection in my ActionForm, and want to access just the
first object in that Collection.
How can I do this?

Mick-
Or you could use map entry..
<c:forEach var="entry" items="${QUERYRESULT["FormName"]}">
<c:out value="${entry.key}"/> -
<c:forEach var="eo" items='${entry.value}'>
${eo.name.value}
</c:forEach>
</c:forEach>
HTH,
Martin-
