Why? Can you elaborate? Test against index value of 0 will work for collection size
of 1, 2, or n. The only problem I can see is if your collection is empty; in which
case this technique will result in a dot. You can work around this by testing before
iterating.

Using some Java.
<nested:nest
property="someProperty"/>
<nested:define
id="theCollection"
property="someCollection"/>
<%
int sizeMinusOne == theCollection.size() - 1;
%>
<nested:iterate
property="someCollection"
indexId="index">
<logic:notEqual
property="index"
value="<%=sizeMinusOne%>">,</logic:notEqual>
</nested:iterate>
.
</nested:nest>
