SSI框架 No result defined for action

Question

小弟这几天用 struts2 + spring + ibatis 搭了一个程序。能进入登陆界面，登陆后我用 debug 看了，action 能正常运行，并返回 success(or error)。但是页面上却显示type Status reportmessage No result defined for action login.action.LoginAction and result successdescription The requested resource (No result defined for action login.action.LoginAction and result success) is not available.
我找了几天也没找出问题，麻烦各位大牛帮忙看看。下边是代码struts.xml<?xml version="1.0" encoding="UTF-8" ?>
