First of all, I want to thank the Apache Axis2 developers and Axis2 community who have contributed towards making this Web Services framework a world-renowned success in a relatively short period of time. Thank you!

I would like to thank Dr Sanjiva Weerawarana, Founder, Chairman and CEO of WSO2, Inc., without whose support, vision, guidance, and belief in my work this effort would never have been realized. I owe countless thanks to my parents and dear wife for always being there and supporting me in so many ways. This book would not have been possible without everything that they have done for me. Special thanks to my colleagues Suran Jayathilaka, Devaka Randeniya, and Charitha Kankanamage for reviewing my writings, validating the samples, providing insight, and contributing to this effort in many other ways. Special thanks to Srinath Hemapani, Ajith Ranabahu, Eran Chinthaka, Davanam Sirinivas, Glen Daniels, Paul Fremantle, Chathura Herath, Jaliya Ekanayake, and all other key members of the Axis2 team without whose tremendous contributions and wisdom Axis2 would not have been possible. For the creation of this work, I am blessed with a strong team of technical reviewers, superior editorial and production professionals from Packt Publishing. My sincere thanks to all of you for your tireless efforts.
