Oracle ADF Real World Developer's Guide

Chapter 2. Introduction to ADF Business Components

The crux of any enterprise application is its business logic implementation. The business service layer of a fusion web application is built using Oracle ADF Business Components. This chapter gives you an overview of ADF Business Components, which includes discussion on the following topics:

Business service layer
Overview of ADF Business Components
Building a simple business service
Oracle ADF Model Tester
Java test client for Business Components
Understanding the runtime behavior of ADF Business Components

The intention of this chapter is to provide you with a brief description of ADF business components. This should hopefully help you to understand the larger picture when we discuss individual business components in the next chapters. If you are already familiar with ADF Business Components, you are free to skip this chapter and move on to the next chapter.

Oracle ADF Model Tester

Smoke testing of the business model implementation is essential for the success of any application development. The JDeveloper comes with a Graphical User Interface (GUI) based Model Tester to test your business components.

To test the business components, select the application module in the Application Navigator window, right-click on it, and choose Run or Debug. JDeveloper will display the Oracle ADF Model Tester window as shown in the following screenshot:

The ADF Model Tester tool will let you test the data model that has been exposed through an application module. This includes executing view object instances to query the datasource, traversing master-child view object instances linked though view links by modifying the attribute values, committing or rolling back a transaction, and invoking business methods.

A quick walkthrough of the commonly used ADF Model Tester toolbar buttons is as follows:

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

Chris Muir Nov 12, 2012

Disclaimer: I'm an Oracle ADF Product Manager.As part of my regular job I've read *every* book on ADF. Given there's now several ADF beginners' books I thought the introductory level to ADF area was already amply covered, and I didn't know what Jobinesh's latest ADF text could add. However I must admit I was pleasantly surprised, as even though this book obviously covers many beginners topics, it also covers topics the others haven't making it another valuable addition to the ADF textbooks currently available.Of particular interest to me was the introduction of:1) Framework class diagrams - explaining for example how the ADF BC and binding layer classes relate to each other, therefore giving insight into what objects you actually work with programmatically when you drop to code in ADF2) JSF Servlet, ADF Servlet & Filter lifecycle - a soup-to-nuts discussion starting at the configuration of the web.xml, the importance of the order of the filters, and the overall lifecycle of the framework3) Application Module scenario diagrams - what objects and methods get called when an Application Module is instantiated so not only do you get an abstract discussion of the AM lifecycle, but how it relates to actual code.Don't get me wrong, Jobinesh covers all the usual beginner topics, ADF Business Components, task flows, ADF Faces and more, but the fact that he's focused on the Java and Java EE side of ADF brings two very useful discussions on the framework together, which I believe creates a good learning opportunity.A recommended read for beginners.

This is one of the best books available in the market to master ADF.Contains lot of practical examples which are really useful to become an expert in ADF.My favorite part is the bean snippets. You can see tons of code snippets which you can utilize in your projects.

Best book in ADF

Frank Nimphius Nov 23, 2012

This book really found itself a niche in the existing Oracle documentation and books that exist.In his book Jobinesh addresses beginners as well as expert ADF programmers. Unlike existing books, this book has a string focus and strong expertise shared on ADF Business Components as the business service. The book provides a detailed look at how entities, view objects and application modules are defined and how they work at runtime. In addition you learn a lot of advanced hints and tips that really will accelerate your skill set to a professional level.Though book has a strong set on ADF Business Components, this is not all Jobinesh has to share. The ADF binding layer, view layer and controller are covered equally well, making the book a joyful reading and a necessity for ADF developers. As mentioned, it founds it niche and - though having some overlaps - greatly adds to the written content available for Oracle ADF.My recommendation: Buy it. This book is worth every dime.

Serafeim Karapatis Dec 15, 2012

It is interesting to compare this book with Oracle's online developer's guide, which actually counts over 1800 pages. At first sight, the book structure resembles that of official documentation. However, it is superior to examples and abundance of source code. It covers in detail many of the interior aspects of the framework that have not been described elsewhere, such as how locking works, managing transactions in different layers, the ADF lifecycle, metadata files and much more. Particular emphasis is also given into ADF Java APIs. Jobinesh, a well respected ADF architect and blogger, when refers to a subject, he often describes very thoroughly how it works, providing examples of available APIs and also citing execution flows at runtime. On the other hand, on issues that are already well provided by official documentation or by online resources, he gives a brief description and direct referrals in order to avoid repetition. Finally, it is worth mentioning that the relevant (rich) code downloads section cover all examples of the book, and is perceived as a great gift.The contents of the book includes twelve chapters, half of which relate to the ADF BC and four to ADF Faces and ADF Controller. There are two chapters of mixed content about validations and best practices. The persistence on technical detail makes the book invaluable for middle-level and senior ADF developers ADF, but I would not recommend it for first ADF reading for those who are coming from a 4GL (Oracle Forms) or Java / JEE background.A quick walk-through of the content. The first chapter ("Getting started with Oracle ADF") describes a short demonstration of ADF development. Then ("Introduction to ADF Business Components") briefly deals with the ADF BC, the query and transactional modes of operation, accompanied with comprehensive UML sequence diagrams and corresponding details. We continue with the description of entity objects (chapter 3) and view objects (Chapter 4) covering all their great potential both at declarative and programming level. The lifecycle events of entities and view objects are the subject of "Advanced Concepts on Entities Objects and View Objects" which is a wonderful presentation of the related APIs for transactional and query operations. Equally interesting is the chapter on Application Modules, covering various aspects of customization (tuning parameters, shared modules, passivation, savepoints, etc.)In the chapter "Binding Business Services with the User Interface" we learn a lot about the different types of ADF bindings, the metadata files and a probable interfacing with Servlets. After that ("Building Data Bound Web User Interfaces") ADF Faces components are described, their binding with the ADF model, iterators, and the advanced configuration of ADF query panels. Chapters 9 and 10 refer to the ADF task flows, transactional management in regions, in ADF trains and there is also a interesting reference to savepoints. In "More on Validations and Error Handling" we see details about their handling at the level of ADF Faces and ADF Model. Chapter 12 ("Oracle ADF Best Practices") encapsulates several recipes for project organization and cites configuration options for achieving greater performance and scalability to our ADF applications and thus concludes the book perfectly.Therefore, for those who want to expand their knowledge in the ADF, to understand its internals and capabilities, and also learn many configuration options (and corresponding APIs) then this book is a one stop shop. The author describes each feature in high depth and by giving multiple perspectives. I believe that the book would be even more complete if it included more details about the ADF Faces as well as advanced features such as using javascript, personalization, testing practices, etc, which are also relevant to many real world cases.
