I am trying to run my struts application but I am getting a error action is not mapped I have seen the namespace it is correct but still getting the error?
struts.xml ：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="false" />
<include file="register.xml"/>
<!-- Add packages here -->
</struts>
我的 register.xml ：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="register" namespace="/" extends="struts-default">

<result name="input">/register.jsp</result>
<result type="redirectAction">register.jsp</result>
</action>
<!-- Add actions here -->
</package>
</struts>
我正在验证我的注册页面和验证XML如下
I am validating my register page and the validation XML as follows
RegisterAction-validation.xml：
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
<field name="username">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
</field>
<field name="password">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
<field-validator type="stringlength">
<param name="minLength">6</param>
<param name="trim">true</param>
<message key="requiredpassword"/>
</field-validator>
</field>
<field name="email">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
<field-validator type="email">
<message key="requiredemail"/>
</field-validator>
</field>
<field name="gender">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
</field>
<field name="postalcode">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
<field-validator type="regex">
<param name="expression"><![CDATA[^\d*$]]></param>
<message key="requiredinteger"/>
</field-validator>
</field>
</validators>
我的 register.jsp 如下：
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Validation Struts page</title>
<s:head/>
</head>
<body>
<s:form action="Register">
<s:textfield key="username"/>
<s:password key="password" />
<s:textfield key="email" />
<s:select headerKey="" headerValue="Select Gender"
key="gender" list="#{'M':'Male','F':'Female'}" />
<s:textfield key="postalcode" />
<s:submit/>
</s:form>
</body>
</html>
我的项目结构如下：
Strutsvalidation
--src-->
com.struts2(package)-->
register.xml,
registeraction-validation.xml,
javaclasses,
struts.xml
--webcontent-->
web-inf-->
web.xml
register.jsp(in web content)
我是得到错误如下？

推荐答案
此配置错误
<result type="redirectAction">register.jsp</result>
使用
<result>/register.jsp</result>
redirectAction 结果应该用于重定向到该操作，该名称用于位置。
The redirectAction result should be used to redirect to the action, which name is used for location.
当您使用 s：form 标记时，例外情况来自试图提交它。实际打包在命名空间 / 中的操作注册。这不是默认命名空间，因此应该在s：form标签上使用。
The exception comes from the s:form tag when you tried to submit it. The action Register actually packaged in namespace /. This not a default namespace and therefore should be used on the s:form tag.
<s:form namespace="/" action="Register">
