Question

There is no Action mapped for namespace /jsp/user and action name user_add_action. - 怎么改啊

struts
<package name="mypackage" namespace="/user" extends="struts-default">
<action name="user_add_action" class="com.clps.bbs.action.User_Add_Action">
<result name="success">/login.jsp</result>
<result name="error">/jsp/error.jsp</result>
</action>
</package>
jsp
<FORM name="regForm" onSubmit="check()" action="user/user_add_action" method="post">

Answer 1

namespace="/"和namespace="/user"是不同的，你访问时网址上写的路径一样，

Answer 2

把
<package name="mypackage" namespace="/user" extends="struts-default">

改成
<package name="mypackage" namespace="/jsp/user" extends="struts-default">

试试
