Foreword

First and foremost, let me say what an honor it is to participate in the great work

that Antony Reynolds and Matt Wright are doing through this Oracle SOA Suite

Developer Guide. The original edition of the book provided SOA developers with

practical tips, code examples, and under-the-covers knowledge of Oracle SOA Suite

and has received extremely positive feedback from our developer community. This

edition carries forward all of those benefits, but is completely updated for the 11gR1

release of Oracle SOA Suite, which brings with it not only new features and APIs,

but also some very significant architectural changes.

The original edition filled a very important need for the developer community,

going beyond basic documentation to provide best practices and tips and tricks for

Oracle SOA Suite developers. Antony and Matt were just the right people to create

such content, each having many years hands-on experience of enabling Oracle

SOA Suite implementations for customers and partners, as well as a close working

relationship with Oracle's SOA engineering and product management teams.

However, I believe this update for the 11gR1 release will be even more valuable

to the developer community.

With 11gR1, Oracle invested a tremendous amount of engineering work to not

just integrate, but unify the components that make up the Oracle SOA Suite. This

was done across many areas - adapters, service bus, routing, process orchestration,

business rules, B2B / partner integration, business activity monitoring, and complex

event processing. To achieve this unified experience, new micro-kernel based run￾time architecture was created, called the Service Infrastructure, and new standards

such as SCA (Service Component Architecture) were implemented. These advances

bring great benefits to customers around ease-of-use, manageability and scalability;

however, there is naturally a learning curve with the new features and also new

architectural factors that come into play. For example, architects and developers

will now consider not just how to decompose their requirements into Services and

Processes, but also determine what level of granularity their SOA Composites

should be at.

www.it-ebooks.info

As such, besides the many updates and descriptions of new components, Antony

and Matt have also added critically valuable new content on advanced SOA

architecture considerations. I believe that this alone will make this book uniquely

useful for Oracle SOA Suite developers.

Especially coming so soon after the 11gR1 release, the updated content in this

book, including areas such as exception handling, testing, security and operational

automation, will surely be invaluable to anyone working with Oracle SOA Suite.

But even more difficult to find is the information that Matt and Antony have from

working with customer implementations around edge cases, design patterns,

and how these products best fit into the full development lifecycle. This kind of

information comes only from real-world project experience, such as Antony and

Matt have.

I believe that this book will help developers realize their goals with the Oracle SOA

Suite, helping them increase productivity, avoid common pitfalls, and improve ROI

through more scalable, agile, and re-usable implementations. On behalf of the Oracle

SOA Engineering and Product Management team, as well as all the customers and

partners who have asked for this book, we heartily thank Antony and Matt for the

investment of their time and energy and hope that this updated edition help you

achieve your goals with the Oracle SOA Suite.

About the Authors

Antony Reynolds has worked in the IT industry for more than 25 years,

after 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

Mathematics 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 the 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 the chief design authority and security architect.

After the publication of his previous book, the SOA Suite 10g Developers Guide,

Antony changed roles within Oracle, taking a position in the global customer

support organization. As part of this change of position he moved from a small

village outside Bristol, England to a small town outside Colorado Springs, Colorado.

He is now acclimatized to living at 7,500ft and has learnt to survive on less oxygen.

Within support, Antony deals with customers who have problems with large

complex SOA deployments, often working as an advisor to other support analysts.

Antony also has a role in training support analysts in SOA principles and details of

the Oracle SOA Suite.

Outside of work Antony helps with scouting at church, which gives him the

opportunity to spend time with his two eldest sons. 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. Antony is a slow but steady runner and can often

be seen jogging up and down the trails in the shadow of the Rocky Mountains.

Acknowledgement

I would like to thank my wife Rowan, and my four very patient children, who have

put up with my staying at home on family trips and working late nights in my

basement office. My colleagues in support have often volunteered to be reviewers

of material and have been the unwitting guinea pigs of new explanations. The

reviewers have provided invaluable advice and assistance, challenging me to

explain myself better and expand more on key points.

Matt has been a constant source of enthusiasm and energy and with Prasad and

Swapna at Packt has helped keep me to some sort of schedule.

Finally, thank you to the development team at Oracle under Amlan Debnath, who

have enhanced and improved the SOA Suite product significantly in this release.

I would particularly like to mention Clemens Utschig, who has expanded my

understanding of SOA Suite internals and without whom Chapter 15 in particular

would be much less complete.

Acknowledgement

Well, this is the book that Antony and I originally intended to write, when we first

put pen to paper (or finger to keypad) back in May 2007. At this point the 11gR1

version of the Oracle SOA Suite was still in the initial stages of development, with

the goal being to time the publication of the book with the release of 11gR1. Then in

early 2008 Oracle announced the acquisition of BEA, which it finalized in July; at this

point future timings around the release of 11gR1 were very much up in the air.

By this stage a significant amount of the book was already written, and we had

received some really positive feedback from the initial reviews. With this in mind,

Antony and I took the decision to retarget the book for the current 10gR3 release and

bring in the Oracle Service Bus (formally known as the BEA Aqualogic Service Bus).

The first version of the book was published in March 2009, almost two years after our

original start date, and much to the relief of anyone closely connected with Antony

or I. Then in July, Oracle announced the release of the Oracle SOA Suite 11gR1,

Antony and I blinked and then decided to write the 11gR1 version of the book, in

many ways it was unfinished business!

So while this edition has been produced significantly quicker, it's still almost three

years since we began this journey; a journey that we would not have been able to

complete without the support of many others. First, I would like to express my

gratitude to everyone at Oracle who played a part; in particular to David Shaffer,

Demed L'Her, Prasen Palvankar, Heidi Buelow, Manoj Das, Neil Wyse, Ralf Mueller,

Mohamed Ashfar, Andy Gale and all the members of the SOA Development Team.

I would also like to express my deep appreciation to everyone who has reviewed

this book, the original reviewers: Phil McLaughlin, Jason Jones and James Oliver.

Also the reviewers who helped with this edition: Bill Hicks, Normann Hajo, Manoj

Neelapu, Hans Forbrich, Shu Xuan Nie, Marc Kelderman and John Deeb. Their

invaluable feedback and advice not only helped to validate the overall accuracy of

the content, but more importantly ensure its clarity and readability.

A book like this doesn't make it into print without a lot of work from the publisher.

I would like to thank the team at Packt Publishing for all their support; especially

James Lumsden, Swapna Verlekar, and Prasad Rai.

A special mention must go to John Deeb, for his continual encouragement, input and

above all support in ensuring that I found time to write the book. I couldn't ask for a

more supportive friend and business partner.

Finally, I would like to say a very, very special thank you to my wife Natasha and

my children Elliot and Kimberley, who for the past three years have been incredibly

patient and supportive in allowing me to spend far too many evenings and

weekends stuck away in my office writing these books.
