2) Copy the following configuration for the Struts2 FilterDispatcher (which acts as the Controller) in the web.xml file of the Web Application
<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>
3) Create the HelloWorld.java class which is a POJO (and acts as the action class in Struts 2)
package info.icontraining.struts2;
public class HelloWorld {
private static final String GREETING = "Hello ";
public String execute() {
setCustomGreeting( GREETING + getName() );
return "success";
}
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
private String customGreeting;
public String getCustomGreeting() {
return customGreeting;
}
public void setCustomGreeting( String customGreeting ) {
this.customGreeting = customGreeting;
}
}
4) Create the NameCollector.jsp in the WebContent folder
<%@ page contentType="text/html; charset=UTF-8" %>

<html>
<head>
<title>Name Collector</title>
</head>

<html>
<head>
<title>HelloWorld</title>
</head>
<body>
<h1><s:property value="customGreeting"/></h1>
</body>
</html>
6) Create the Struts2 Configuration file, struts.xml in the src folder of the Web Application (in the default package)
<?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">

</action>
<action name="HelloWorld" class="info.icontraining.struts2.HelloWorld">
<result name="success">/Hello.jsp</result>
