<s:form action="saveOrUpdateList" method="post">
<s:push value="users">
<s:iterator value="userList" status="userStatus">
<tr
class="<s:if test="#userStatus.odd == true ">odd</s:if><s:else>even</s:else>">
<td><s:property value="name" /></td>
<td><s:checkbox name="mailingList" value="mailingList"/>

</s:iterator>
<s:submit />
</s:push>
</s:form>
</table>

And in my action class
public String saveOrUpdateList()
{
try {
System.out.println("inside saveOrUpdateList");
System.out.println("execute called size of list : " + userList.size());

for (Users nn : userList) {
System.out.println("dffsddf " + nn.getId());
