Struts 2 running hello world application

Simple Hello world example to show how to run a struts 2 application in eclipse and tomcat

Step 1:

Create an html file and design a simple form using struts tag lib

<%@ taglib prefix="s" uri="/struts-tags"%> 
<html>
<body> 
	<h4>
		<u>Struts2 Hello World Example</u>
	</h4>
	
	<s:form action="hello" >
		<s:textfield name="uname"  label="Enter Username"/>
		<br>
		<s:password name="pass" label="Enter Password" />
		<br>
		<s:submit value="Sign In" align="center" />
	</s:form>  
	<br>

	
</body>
</html>

Step 2:

Configure your web.xml file to map all request to Struts built in filter StrutsPrepareAndExecuteFilter

<?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.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>



</web-app>

Step 3:

Create struts.xml file in src directory(default location to keep your struts configuration file)

<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<package name="default" extends="struts-default">			
		<action name="hello" class="com.candidjava.controller.HelloWorld">		
			<result name="success">/success.jsp</result>			
		</action>		
	</package>
</struts>

Step 4:

Create an Controller class that extends ActionSupport and override execute method init.

package com.candidjava.controller;
import com.opensymphony.xwork2.ActionSupport;
public class HelloWorld extends ActionSupport{	
	
	private static final long serialVersionUID = 1L;
	
	private String uname;
	private String pass;

	public String getUname() { 
		return uname;  
	}

	public void setUname(String uname) {
		this.uname = uname;
	}
	  
	public String getPass() {
		return pass;
	}

	public void setPass(String pass) {
		this.pass = pass;
	}

	public String execute()
	{		
		System.out.println(uname);
		System.out.println(pass);
		
		return "success";
	}
	
	
}

Step 5

Create success.jsp file to redirect view page

<%@ taglib prefix="a" uri="/struts-tags" %>


Properties binded in Struts controller can be retrived in view pages. <br>

Welcome <b><a:property value="uname"/>,</b><br/>
