dwr的include有关问题

昨天碰到一个问题无法解决，知道的话帮一下。谢谢

将这个类暴露给客服端：

public class MessageDwr 
{
	//该前端处理类所依懒的业务逻辑组件
	private MessageService messageService;
	public void setMessageService(MessageService messageService)
	{
		this.messageService = messageService;
	}
	//创建一条消息
	//虽然提供了HttpSession参数，但浏览器javascript调用时无需传入该参数由DWR负责导入
	public int createMessage(String title , String content , HttpSession session)throws MessageException
	{
		Integer userId = (Integer)session.getAttribute("userId");
		Message m = new Message();
		m.setTitle(title);
		m.setContent(content);
		return messageService.createMessage(m, userId);
	}
	//创建一个用户
	public int createUser(String user , String pass , HttpSession session)throws MessageException
	{
		User u = new User();
		u.setName(user);
		u.setPass(pass);
		int userId = messageService.createUser(u);
		session.setAttribute("userId", userId);
		return userId;
	}
	//处理用户
	public int loginPro(String userName , String pass , HttpSession session)throws MessageException
	{
		User user = new User();
		user.setName(userName);
		user.setPass(pass);
		int userId = messageService.validateLogin(user);
		if(userId>0)
		{
			session.setAttribute("userId",userId);
		}
		return userId;
	}
	//判断当前页面浏览者是否已登录
	public int isLogin(HttpSession session)throws MessageException
	{
		Integer userId = (Integer)session.getAttribute("userId");
		if(userId != null && userId>0)
		{
			return (Integer)userId;
		}
		return -1;
	}
	//根据消息Id返回消息
	public MessageBean getMessage(int msgId , HttpSession session)throws MessageException
	{
		return messageService.getMessage(msgId);
	}
	//返回指定也所显示的全部消息
	public List<MessageBean> getAllMessageByPage(int pageNum , HttpSession session)throws MessageException
	{
		return messageService.getAllMessageByPage(pageNum);
	}
}

dwr.xml文件是：

<dwr>
	<allow>
		
		<create creator="spring" javascript="ms">
			<param name="beanName" value="messageDwr"/>
			<include method="createMessage"/>
			<include method="createUser"/>
			<include method="loginPro"/>
			<include method="isLogin"/>
			<include method="getMessage"/>
			<include method="getAllMessageByPage"/>
		</create>
		<convert match="vo.MessageBean" converter="bean"></convert>
		<convert match="com.message.exception.MessageException" converter="bean"/>
	</allow>
	
</dwr>

我已经使用了include为什么还会这样：

怎么会有Object类里的方法,不是已经使用的include了吗，怎么回事,?
