嵌套<iterator>，然后实现；
具体如下：

<s:iterator value="#request.assetCateSuperList" id="assetCateSuperList">

<s:property value='name'/> -- <s:property value='id'/>"
<s:iterator value="#assetCateSuperList.products">
(<s:property value="name"/> -- <s:property value="id"/>
</s:iterator>

</s:iterator>

<ww:iterator value="userlist" status="number">
<tr> <td> <ww:property />{??} </td>
<td> <ww:property value="topiclist[#number.index]" />{??} </td> <tr>
</ww:iterator>

Answer 3

采用list类，代码如下：
List users = new ArrayList();
users.add("zhangsan");
users.add("lisi");
Iterator its = users.iterator();
while (its.hasNext()) {
System.out.println(its.next());
}
