Answer 1

忘贴了 HTTP Status 404 - /shopping/admin/orderAction--------------------------------------------------------------------------------type Status reportmessage /shopping/admin/orderActiondescription The requested resource (/shopping/admin/orderAction) is not available.

Answer 2

路径写错了啊，你是从一个模块转到另一个模块还是就在shopping模块中请求这个action?

Answer 3

shopping是系统的名字，这是订单查询功能，输入订单号后按确定，在新的页面中显示结果

Answer 4

404，没有找到请求的资源，好好看看自己的路径，注意区分web应用路径和域名访问路径。

Answer 5

配置没问题，jsp路径写错了。
form就直接 <form action="/admin/orderAction.do">

Answer 6

action的配置错误，或者访问的地址不对
