    <!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd"><xwork>    <include file="webwork-default.xml" />    <package name="default" extends="webwork-default">        <default-interceptor-ref name="completeStack" />        <action name="HelloWorld" class="com.aeolia.action.HelloWorld">            <result name="success">hello.jsp</result>            <result name="input">name.jsp</result>        </action>    </package></xwork>
    View Code

    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"    pageEncoding="MS932"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><%@taglib prefix="ww" uri="webwork"%><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Insert title here</title></head><body>    Show message    <ww:property value="message" /></body></html>
