本文将介绍如何在Struts2框架中使用JSP页面，并通过web.xml配置实现Struts2过滤器，演示了一个简单的helloworld示例。

1.helloworld.jsp

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>helloworld页面</title>
  </head>
  <body>
    helloworld,struts2!
  </body>
</html>

2.web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <filter>
  	<filter-name>struts2</filter-name>
  	<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
  	<filter-name>struts2</filter-name>
  	<url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

xwork-core-2.1.6.jar
4.Action类

package com.hitsoft.action;
public class HelloWorld{

	public String execute() throws Exception {
		return "success";
	}
}

<struts>
    <package name="struts2"  extends="struts-default">

		<action name="helloworld" class="com.hitsoft.action.HelloWorldAction">
