無法找到Struts調度程序

Question

我可以在我的代碼中發現一個錯誤，請幫助我處理以下錯誤。

在build.xml

<?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_2_5.xsd" 
    id="WebApp_ID" version="2.5"> 
    <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> 

的index.jsp

<s:form action="verify"> 

    <s:textfield name="uname" label="Enter Username"/> 
    <s:textfield name="pass" label="Enter the Password"/> 

    <s:submit value="Click" align="center" /> 

</s:form> 

異常

org.apache.jasper.JasperException: 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]

廣場web.xml文件ü nder WEB-INF文件夾。我也遇到了同樣的問題，但將web.xml文件放在正確的位置解決了問題。
