Acknowledgments

When acknowledging all the people involved in getting a book from concept to print, the list can be pretty big. But there are always a few who stand out in the task, both directly and indirectly. The major push came from the people who bought our ebooks which focused on niche topics. Without them we wouldn't have ventured into writing this full fledged book.

Writing is not our special skill but writing a technical book was much easier compared to any other book. A special thanks to be rendered for our friends and colleagues who had supported this book with their special review and inputs.

We are interested more in communicating the knowledge we acquired over the years rather than providing a novel book. Thanks for everyone who stood by this book and made it possible at the end.

As I keep on saying ' An expert is not the one who knows everything but willing to share what he knows'.

Introduction

From being a business super user to an implementer, I am a firm believer in utilizing ERP business systems to achieve the wealth of information required and standardization to run businesses effectively today. The technology we used for creating user interface for Oracle EBS is very ancient and today's modern world application support web interface for better user experience. Whenever we tried to access the Oracle EBS through internet,most often than not you will have some issues with jinitiator in case of 11i and ojvm incase of Oracle R12. OA Framework offers a convenient way to develop some stunning web application with lesser effort. In our earlier cycle of learning OA Framework,it was not smooth and we had done the tutorials that came with oracle again and again blindly without understanding what we are performing. Since none of us had the java background,it was really an uphill task. It took 6 long years to reach the current level of knowledge on OA Framework. Having trained more than 300 people on OA Framework now,we had learned a lot from the perspective of the learners. When we introduced the OA Framework online training for the first time,none of the learners were comfortable till we cracked the remote desktop approach for the learning methodology.

This book, while designed to be read from cover to cover, is also self-inclusive for each section, allowing the reader to go directly to a particular section and not be referenced back to other areas for more information. For Oracle or industry-specific terms, a glossary at the back is included for rapid access. Besides being a step-by-step and field-by-field how-to guide, this book includes many business considerations to think about during an development cycle and beyond.

Note : This book is not a replacement for Oracle's Developer Guide. Oracle OAF developer guide is very extensive and should be used as a primary reference and this book can be used by the beginners to understand the concepts and get accustomed to OAF development and extension.
