Book Review: Developing Web Applications with Oracle ADF Essentials

Book cover from
Oracle ADF is a framework for building Rich Web applications with Java which is built on top of Java EE. So if you have previous experience in building Web applications using JSF you are likely to start developing with Oracle ADF pretty fast. On the contrary, if you are just beginning with Web development, the visual and declarative development that this framework offers will let you build your applications in a fast pace.

In this post, I'll be reviewing the book "Developing Web Applications with Oracle ADF Essentials" written by Sten E. Vesterli and published by PACKT. Although this book covers the version, the concepts are the same as of the latest version ( released a couple of months ago), it is a great book to get you started with Oracle ADF Essentials. The chapters are easy to read, they follow a tutorial approach and a summary at the end. You will learn what you need in order to build a Web application using a "free software" stack: JDeveloper IDE, ADF Essentials, Glassfish application server and MySQL database. This is an introductory book, so you won't find what every single property of the framework means, but it does have advance topics such as: how to configure ADF applications to be developed as shared libraries, how to implement security for an ADF Essentials application (remember ADF security is not part of ADF Essentials), among others.

IMHO when you are using ADF Essentials with other databases rather than Oracle DB you won't be able to use the full power of ADF (or ADF Essentials) and sometimes you'll find yourself looking for workarounds in order to achieve some behavior that with Oracle DB you get out-of-the-box.

From chapters 1 to 4 you will learn the basics of building an Orace ADF Essentials application and whenever there's a different behavior for using MySQL database, you'll get a tip or note clarifying this. You will also get several useful URLs pointing you to other sources of information. The chapters are tutorial like, you will be building an application with two use cases covering the core ADF Essentials technologies: Business Components for Java (BC4J) and ADF Faces.

On chapters 5 to 8 is where you get the advance training. Building enterprise like applications requires changes in your application structure and this book teaches you how to do it and what you need to have in mind when building such applications. Another important feature is debugging and ADF has its own way to deal with it, the book shows you the way you can configure your application in order to enable debugging at different levels. I really liked that chapter 7 is about securing your ADF Essentials application but it was not only limited to using JAAS, you will learn how to configure and use the Apache Shiro security framework in order to address the lack of the security mechanism in ADF Essentials. Last but not least, you'll see how to configure ANT in order to automate your building process, this is pretty useful when you are working on big projects.

Overall, I liked the book, learned new things and from now I'll try to blog about some ADF + MySQL workarounds that I have used in my projects.
