i iterate over the arraylist in a c:forEach loop. there i set the
properties of the arraylist like this:
<c:forEach var="currentp" items="${buyOnlineForm.chosenProducts}"
varStatus="itemStatus">
<html:select name="currentp" property="product" indexed="true"
style='width: 100px;'>
<html:options name="currentp" property="productSelectionOptions"/>
</html:select>
....
</c:forEach>
where chosenProducts is an array list with beans. the bean has the
property product. you can see that the html:select tag is indexed. so i
can iterate dynamically with regexp over all the parameters passed on
submit.

sorry, i meant "implement in a ActionForm class".
