To encapsulate this data, we'll use a simple Java class that follows the basic Java Bean specifications (public set/get methods for each instance field). If you're following along add this class to package org.apache.struts.register.model in the Coding Struts 2 Actions example.

Code Block

	java
	java
title	Person.javajava

public class Person
{
    private String firstName;
    private String lastName;
    private String email;
    private int age;

    public String getFirstName()
    {
        return firstName;
    }

    public void setFirstName(String firstName)
    {
        this.firstName = firstName;
    }

    public String getLastName()
    {
        return lastName;
    }

    public void setLastName(String lastName)
    {
        this.lastName = lastName;
    }

    public String getEmail()
    {
        return email;
    }

    public void setEmail(String email)
    {
        this.email = email;
    }

    public int getAge()
    {
        return age;
    }

    public void setAge( int age)
    {
        this.age = age;
    }


    public String toString()
    {
        return "First Name: " + getFirstName() + " Last Name:  " + getLastName() + 
        " Email:      " + getEmail() + " Age:      " + getAge() ;
    }
}

...

To collect the above information we'll use a Struts 2 form. When creating this form the key concept we need to employ is to tie each form field to a specific instance field of an object of type Person. Let's look over the form first and then discuss some key points. Create a view page named register.jsp (in WebContent (Ant version) or src/main/webapp (Maven version) )

Code Block

<h3>Register for a prize by completing this form.</h3>

<s:form action="register">

 	  <s:textfield  name="personBean.lastName" label="Last name" />
 	  <s:textfield name="personBean.email"  label ="Email"/>  
 	  <s:textfield name="personBean.age"  label="Age"  />
 	  
   	  <s:submit/>
   	  
</s:form>	
 
</body>
</html>

Here is the Action class used for this example. Place it in package org.apache.struts.register.action.

Code Block

	java
	java
title	Register.java Struts 2 Action Classjava

package org.apache.struts.register.action;

import org.apache.struts.register.model.Person;

import com.opensymphony.xwork2.ActionSupport;

public class Register extends ActionSupport {
	
	private static final long serialVersionUID = 1L;
	
	private Person personBean;
	

	@Override
	public String execute() throws Exception {
		
		//call Service class to store personBean's state in database
		
		return SUCCESS;
		
	}
	
	public Person getPersonBean() {
		
		return personBean;
		
	}
	
	public void setPersonBean(Person person) {
		
		personBean = person;
		
	}

}

...

When SUCCESS is returned by the execute method we want to display a simple thank you page that shows the user's registration. Add the thankyou.jsp below to either WebContent (Ant) or src/main/webapp (Maven).

Code Block

title	thankyou.jsphtml

<?xml version="1.0" encoding="ISO-8859-1" ?>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Registration Successful</title>
</head>
<body>
<h3>Thank you for registering for a prize.</h3>

<p>Your registration information: <s:property value="personBean" /> </p>

<p><a href="<s:url action='index' />" >Return to home page</a>.</p>

</body>
</html>

...

To specify the relationship between the form submission page, the Struts 2 Action class, and the success view page we need to add an action node to struts.xml. Add this action node to struts.xml (src folder (Ant version) or src/main/resources (Maven version) ) after the hello action and before the closing package node.

Code Block

	xml
	xml
title	action node for struts.xmlxml

<action name="register" class="org.apache.struts.register.action.Register" method="execute">
  <result name="success">/thankyou.jsp</result>
</action>

...

So that the user can find the registration page, add this link to index.jsp
