我第一次尝试Struts2。我正在尝试创建一个简单的登录应用程序。但是，我收到以下异常/错误：

SEVERE: Exception starting filter struts2
java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.FilterDispatcher

从晚上开始我就想把它修好，但修不好。我搜索了一些资料，但问题并没有解决。我已经安装了Struts 2应用程序所需的6个基本jar文件。以下是我的网站。xml和Struts。xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
    <display-name>Login-reg</display-name>

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>
</web-app>

这是我的支柱。xml文件

<?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" />

        <constant name="struts.custom.i18n.resources"
            value="ApplicationResources" />

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

            <action name="login" method="authenticate"
                class="com.struts2.login.LoginAction">
                <result name="success">Welcome.jsp</result>
                <result name="error">Login.jsp</result>

            </action>
        </package>
    </struts>
