使用struts2标签再JSP页面中 遍历出我的Action 肿的LIST，应该怎样写啊？

// 查书
public String select() {

list = bookServices.bookServiceSelect(book);
if (list.size() > 0) {
return SUCCESS;
}
return ERROR;
}

使用struts2标签再JSP页面中用s:iterator方法可以遍历action中的list：
1、action中的list

public class ToMainAction extends ActionSupport implements RequestAware
{
private IBoarderDao boardDao = new BoardDaoImpl();
private ITopicDao topicDao = new TopicDaoImpl();
private IUserDao userDao = new UserDaoImpl();
private Map<String, Object> request;
public void setBoardDao(IBoarderDao boardDao)
{
this.boardDao = boardDao;
}
public void setTopicDao(ITopicDao topicDao)
{
this.topicDao = topicDao;
}
public void setUserDao(IUserDao userDao)
{
this.userDao = userDao;
}
public String execute()
{
// 板块列表
List<Board> boards = boardDao.getAllBoard();
List<Integer> count = new ArrayList<Integer>();
List<User> users = new ArrayList<User>();
List<Topic> lastTopic = new ArrayList<Topic>();
if (null != boards)
{
for (Board b : boards)
{
// 回帖数
List<Topic> topic = topicDao.getTopicByBoardId(b.getBorderId());
if (null != topic)
{
int num = topic.size();
count.add(num);
} else
{
count.add(0);
}
// 最近更新
Topic t = topicDao.getLastTopic(b.getBorderId());
lastTopic.add(t);
// 最近更新的作者
User u = userDao.getUserByuId(t.getUid());
users.add(u);
}
request.put("boards", boards);
request.put("count", count);
request.put("users", users);
request.put("lastTopic", lastTopic);
}
return SUCCESS;
}
public void setRequest(Map<String, Object> request)
{
this.request = request;
}
}
2、jsp中遍历写法：
list.jsp
<%@ taglib uri="/struts-tags" prefix="s"%>
<s:if test="#request.boards!=null">
<s:iterator value="#request.boards" id="b" status="st">
<tr>
<td width="6%" height="68">
</td>
<td width="67%">
<div align="left" class="blueSpan">
<img src="images/topic.gif" width="18" height="21" />
<a href="logined/ToListAction?boardId="+<s:property value="#b.borderId"/>+">
<s:property value="#b.borderName" />
</a>
</div>
</td>
<td>
<s:property value=" #request.count[#st.index]" />
</td>
<td>
<br />
<p align="left">
<s:property value="#request.lastTopic[#st.index].title" />
</p>
<br />
<p align="left">
<s:property value=" #request.lastTopic[#st.index].userName" />
</p>
<br />
<p align="left">
修改时间：
<br/>
<s:property value=" #request.lastTopic[#st.index].modifyTime" />
</p>
<br />
</td>
</tr>
</s:iterator>
</s:if>
