关于MultiActionController中方法不能返回含有ModelAndView方法的问题

用的是MultiActionController，访问http://localhost:8080/WBReport/welcomeController.do?action=showList地址报错
错误如下：
[2010-09-28 23:50:12] - org.springframework.web.servlet.PageNotFound -2714414 [h
ttp-8080-5] WARN org.springframework.web.servlet.PageNotFound - No request han
dling method with name 'showList' in class [com.wolfbase.test.WelcomeController]
以前写的代码可以运行，从网上copy如下的例子也不能运行，晕死；后来终于找到问题的原因：
ModelAndView ：org.springframework.web.portlet.ModelAndView;
应该是来自:org.springframework.web.servlet.ModelAndView; 费了1个多小时呀！

package com.wolfbase.test;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.portlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

public class WelcomeController extends MultiActionController {

    private String successView;
    public void show(HttpServletRequest req,
       HttpServletResponse resp) {
     System.out.println("show-WelcomeController");
    }
    public ModelAndView showList(HttpServletRequest req,
            HttpServletResponse resp) {
        Map model = new HashMap();
        model.put("success", "成功");
        return new ModelAndView(this.getSuccessView(), model);
    }

     public ModelAndView addUser(HttpServletRequest req,
             HttpServletResponse resp) {
         Map model = new HashMap();
         model.put("success", "增加用户成功");
         return new ModelAndView(this.getSuccessView(), model);
     }

     public String getSuccessView() {
         return successView;
     }

     public void setSuccessView(String successView) {
         this.successView = successView;
     }

}
