Before You Begin

The Sun Java Studio's Web Application Framework Tutorial introduces developers to the mechanics and techniques used to build Web applications using the Sun Java Studio's Web Application Framework (formerly Sun ONE Application Framework and JATO) tools.

It is intended for developers who are at least somewhat familiar with building web applications using existing Java 2 Platform, Enterprise Edition (J2EE platform)web technologies, but new to building web applications with the Web Application Framework.

Before You Read This Book

This tutorial helps the developer become more familiar with using the Web Application Framework tool within the Sun Java Studio Enterprise 6 developer environment (hereafter referred to as the IDE).

Before starting, you should be familiar with concepts used in building web applications using existing J2EE web technologies, such as servlets and JavaServlet Pages (JSP pages).

How This Book Is Organized

In the following chapter, you will see an overview of the primary features of the Web Application Framework and toolset (IDE) for developing an enterprise web application.

Chapter 1, Before You Start the Tutorial.

In the following chapter, you see an outline of the mechanics of using the Web Application Framework tools to build a J2EE web application.

Chapter 2, Getting Started.

In the following chapters, you create the application infrastructure needed for all subsequent chapters, and add your first Web Application Framework page.

Chapter 4, Tutorial--Section 1.1 Application Infrastructure.

Chapter 5, Tutorial--Section 1.2 Create Login Page.

Chapter 6, Tutorial--Section 1.3 Test Run the Login Page.

In the following chapters, you expand the existing application by adding a SQL-based model, and a page to display that model's data. You then link the two application pages together so they show coordinated data.

Chapter 7, Tutorial--Section 2.1 Prepare Application to Access SQL Database.

Chapter 8, Tutorial--Section 2.2 Create the CustomerModel.

Chapter 9, Tutorial--Section 2.3 Create Customer Page.

Chapter 10, Tutorial--Section 2.4 Test Run the Customer Page.

Chapter 11, Tutorial--Section 2.5 Link Login Page to Customer Page.

Chapter 12, Tutorial--Section 2.6 Run Application.

In the following chapters, you create a Command component that can be reused by many buttons and HREFs within the same application. This is the alternative technique to implementing request handling code in the button or HREF's handle request event inside its parent container view class.

Chapter 13, Tutorial--Section 3.1 Create a Command Component.

Chapter 14, Tutorial--Section 3.2 Add a Logout Link to the Customer Page.

Chapter 15, Tutorial--Section 3.3 Test Run the Login/Logout Command Component.

In the following chapters, you expand the existing application by adding a Web service-based model and a page to display that model's data. You need to register for and download the Google developer's SDK to build a model for a Web service.

Chapter 16, Tutorial--Section 4.1 Prepare to Create a Web Service Model.

Chapter 17, Tutorial--Section 4.2 Create the Google Search Page.

Chapter 18, Tutorial--Section 4.3 Test Run the Google Search Page.

Chapter 19, Tutorial--Section 4.4 Add Results Listing to the Google Search Page.

Chapter 20, Tutorial--Section 4.5 Test Run the Google Search Page.
