If you have followed the exercises in this book, you are ready to build real-world ADF Essentials applications and can consider yourself an ADF Essentials journeyman.I cannot agree more. If you are new to ADF (Oracle Application Development Framework) programming, you probably need to add this cookbook to your toolbox. Unfortunately, some hyperlinks embedded in the book are broken. At the end of this article, you can find the correct links to some of the important topics covered in the book.
ADF Essentials toolkit is used in this book to help you learn ADF programming. The recent released ADF Essentials gives developers a free version of the core components of the ADF framework which they can use to build an end-to-end ADF-based solution including advanced UI components, taskflows, the binding layer and business components or EJBs.
In this book, the author uses a bottom-up approach which introduces you to the ADF programming. A full-blown DVD rental application (in Chap 6) was built, tested and deployed using the following technology stack:
- The free MySQL database
- The free GlassFish application server
- Note that you also need Java Development Kit
- The free ADF Essentials toolkit
- The free JDeveloper development tool
- Oracle also supports ADF Essentials as part of their Oracle Enterprise Pack for Eclipse (OEPE) product.
- Logging configuration
- ADF logging is controlled by the logging.xml file.
- JDeveloper offers a nice interface for managing this file for the built-in WLS.
- Log monitoring
- WLS—logging can be read and analyzed using Oracle Enterprise Manager Grid Control.
- GlassFish—logging can only be read directly from server.log file.
All ADF applications consist of the following parts:
- View layer
- The View layer consists of the pages that are displayed to end users (JSF pages or JSF page fragments).
- ADF Faces is based on JSF and built on top of Trinidad, an open source JSF framework.
- Controller layer
- The Controller layer consists of ADF Task Flows[4,17] that control the flow between the elements of the view layer
- Model layer
- ADF Model is a binding layer to bind the UI (ADF Faces based on JSF) without tight coupling UI components to the back end data model.
- Business Service layer
- The Business Service layer provides services to query and manipulate data.
- There are many ways to build business services—in this book, it uses ADF Business Components, but you can also use, for example, JPA Entities and EJB 3.0 Session beans, POJOs, web services, and so on.
- Database layer
- The Database layer is where your data is stored persistently.
