<s:iterator>使用request输出不了

public class ReserveCheck extends ActionSupport {

   public String execute() throws Exception{

	   ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");

	   IUserDao userDao=(IUserDao)ctx.getBean("userDAO");

	   ActionContext loginCtx= ActionContext.getContext();

	   Map request=(Map)ActionContext.getContext().get("request");

	   List log=userDao.findAllReserve();

       System.out.println(log.size());

       request.put("log", log);

	   return SUCCESS;

   }

}

action使用的类，输出log.size()显示里面有三条记录，但在JSP页面就输出不了。。

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

          <tr>

            <td>

              <s:property value="#log.name"/>

            </td>

             <td>

              <s:property value="#log.gender"/>

            </td>

             <td>

              <s:property value="#log.telphone"/>

            </td>

             <td>

              <s:property value="#log.email"/>

            </td>

             <td>

              <s:property value="#log.intentionbuytime"/>

            </td>

            <td>

              <s:property value="#log.intentioncar"/>

            </td>

          </tr>

        </s:iterator>
