Chapter 3. Creating Task Flows and Pages

In Chapter 2, Creating Business Services, we built the first layer of the application: the business service layer. In this chapter, we will build the actual user interface that the user will interact with. This part of the application consists of the View, Controller, and Model layers, as shown in the following diagram:

As you may remember from Chapter 1, My First ADF Essentials Application:

  • The View layer consists of the pages that are displayed to your users (JSF pages or JSF page fragments)

  • The Controller layer consists of ADF Task Flows that control the flow between the elements of the view layer

  • The Model layer consists of the Data Controls that connect the view/controller layers to the underlying business services
