First of all, I want to thank Apache Axis2 developers and the Axis2 community who has contributed towards making this web services framework a world renowned success in a relatively short period of time. Thank you! I owe countless thanks to my dear wife and parents 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 Srinath Hemapani, Ajith Ranabahu, Eran Chinthaka, Sanjiva Weerawarana, Davanam Sirinivas, Glen Daniels, Paul Fremantle, Chathura Herath, Jaliya Ekanayake, and all the 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 and superior editorial and production professionals from Packt Publishing. My sincere thanks to all of you for your tireless efforts.
