Struts2 struts 2开发登录时的问题

我有几个问题，如果有人能帮我用Struts 2解决这个问题，我会很高兴的。这就是我的问题。当我运行我的简单登录应用程序时，我犯了以下错误：

org.apache.jasper.jaspereException:找不到Struts调度程序

这通常是由于使用Struts标记而没有关联的过滤器造成的。Struts标记仅在请求通过其servlet过滤器时可用，servlet过滤器初始化此标记所需的Struts dispatcher。-[未知位置]

日志如下所示：

Advertencia: StandardWrapperValve[jsp]: PWC1406: Servlet.service() for servlet jsp threw exception
The Struts dispatcher cannot be found.  This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]

}

在src内部，我还有struts.xml：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC
 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

<constant name="struts.enable.DynamicMethodInvocation" value="true" />
<constant name="struts.devMode" value="false" />

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

<action name="Login" class="com.uniway.action.LoginAction">
<result name="input">/Login.jsp</result>
<result name="success" type="redirectAction">/index.jsp</result>
</action>


</package>


<!-- Add packages here -->

</struts>

在WebContent之后，我有index.jsp和Login.jsp，我有以下代码：

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Sign On</title>
</head>

<body>
<s:form action="Login.action"> 
<s:textfield key="username"/>
<s:password key="password" />
<s:submit method="execute"/>
</s:form>  
</body>
</html>

我的404.jsp页面出现了这个问题，这是我的解决方案：

如果您直接访问jsp页面，我们不应该使用
，页面中不能有S2标记——这些标记期望S2特定的功能不会出现在S2未处理的请求中。@Dave Newton
标记仍然有效@如果堆栈上没有文本提供程序，那么它必须做一些明确的事情。嗨，非常感谢，但它不工作：（，为什么？
<action name="Login" class="com.uniway.action.LoginAction">
     <result name="input">/Login.jsp</result>
     <result name="success">/Login.jsp</result>
</action>

<s:submit value="Login"/>
