Matt Wright has been involved with standards-based Service-Oriented Architecture (SOA) since shortly after the initial submission of SOAP 1.1 to the W3C in 2000, and has worked with some of the early adopters of BPEL since its initial release in 2002. Since then, he has been a passionate exponent of SOA and has been engaged in some of the earliest SOA-based implementations across EMEA and APAC.
He is currently a Director of Product Management for Oracle Fusion Middleware in APAC, where he is responsible for working with organizations to educate and enable them in realizing the full business benefits of SOA in solving complex business problems. As a recognized authority on SOA, Matt is also responsible for evangelizing the Oracle SOA message and is a regular speaker and instructor at private and public events. He also enjoys writing and publishes his own blog (http://blogs.bpel-people.com ). Matt holds a B.Sc. (Eng) in Computer Science from Imperial College, University of London.
It seems a long time ago that I first suggested to Antony that we write this book. Since that day there have been numerous twists and turns, not least the acquisition of BEA which resulted in many revisions and re-writes. Having Antony as my co-author throughout this process was invaluable; Antony's continued conviction and enthusiasm throughout was instrumental in ensuring the book finally made the light of day.
Throughout this process, everyone at Oracle has been very supportive. I would like to make a special mention to Andy Gale for guiding us in the right direction when we first suggested the idea and to John Deeb for his continual support and encouragement throughout. I would also like to express my gratitude to everyone in the SOA Development team; in particular to David Shaffer, Demed L'Her, Manoj Das, Neil Wyse, Ralf Mueller, and Mohamed Ashfar who contributed to this book in many ways.
A major part in the quality of any book is down to the reviewers, so I would like to say a big thank you to Phil McLaughlin, Jason Jones, and James Oliver for all their incredibly valuable feedback, which has made this a clearer and simpler book to read.
The staff at Packt Publishing Pvt. Ltd. helped a great deal to make this book a reality. I would like to thank Rajashree Hamine the Project Coordinator, Swapna Verlekar the Development Editor, and Gagandeep Singh the Technical Editor.
Finally, writing a book is challenging at the best of times, to do it whilst re-locating half way round the world from the UK to Australia probably isn't the best timing! So I would like to say a special thank you to my wife Natasha and my children Elliot and Kimberley for their constant support and understanding throughout this period.
Antony Reynolds has worked in the IT industry for more than 24 years, since getting a job to maintain yield calculations for a Zinc smelter while still an undergraduate. After graduating from the University of Bristol with a degree in Maths and Computer Science he worked first for a software house, IPL in Bath, England, before joining the travel reservations system Galileo as a development team lead. At Galileo he was involved in development and maintenance of workstation products before joining the architecture group. Galileo gave him the opportunity to work in Colorado and Illinois where he developed a love for the Rockies and Chicago style deep pan pizza. He joined Oracle in 1998 as a sales consultant and has worked with a number of customers in that time, including a large retail bank's Internet banking project for which he served as chief design authority and security architect.
Antony currently is lucky to work with customers on the early stages of many interesting projects, providing advice on sizing models and architecture for the SOA Suite.
Outside of work Antony is a bishop in the Church of Jesus Christ of Latter Day Saints (Mormons) and is responsible for a congregation of 350. His wife and four children make sure that he also spends time with them, playing games, watching movies, and acting as an auxiliary taxi service.
I would like to thank my wife Rowan, and my four very patient children, who have put up with their husband and father disappearing into his office in the roof far too often. Several reviewers have provided invaluable advice and assistance. Phil McLaughlin of Oracle has been a constant source of encouragement and constructive criticism as the book has homed in on its target platform. Iswarya Dhandapani of Luton Borough Council took the time to try out all my code samples and identify ones which didn't work as well as providing feedback on my chapters from the view of someone who has to use SOA Suite to provide real solutions. Oracle ACE Jason Jones came a little late to the reviewing but managed to review every chapter and made clear what worked for him and what didn't. Simone Geib of Oracle Product Management provided valuable feedback on the sections covering Oracle Service Bus. I particularly appreciated the way all the reviewers not only pointed out the problems in the book but also identified the positive parts. Edwin Khodabachian is no longer with Oracle, but his team created the BPEL Process Manager at Collaxa, which was bought by Oracle and became under Edwins guidance the foundation of the SOA Suite. Finally, I would like to express appreciation to Thomas Kurian at Oracle who had the vision of a single integrated product suite, the Oracle SOA Suite, and has always been willing to listen to provide advice and guidance to me.
