提交后就报这个错:The requested resource (There is no Action mapped for action name Sum.)

已采纳

The requested resource (There is no Action mapped for action name Sum.) is not available.

下面是代码,很简单的,提示是说没这个映射,麻烦把为什么这样改说下,谢谢

    你这个URL生成没有命名空间是../Sum.action





    /page/positive.jsp

    /page/negative.jsp




    你这个要../struts2/Sum.action才能访问到吧
