Acknowledgement
No book is the product of just the author. He just happens to be the one with his
name on the cover.
A number of people contributed to the success of this book, and it would take more
space than I have to thank each one individually.
A special shout out goes to Sarah Cullington, my editor, who is the reason that this
book exists. Thank you Sarah for believing in me and for being a wonderful guide
through this process. Thank you also to the entire Packt Publishing team for working
so diligently to help bring out a high quality product.
No words can express my gratitude to my amazing development cohort, with whom
it is my privilege to work. In particular, thanks are due to Michael Besosa, Karl Espe,
David Gordhamer, Alok Gupta, Arun Lakkakula, Chad LaVigne, Vladan Pulec,
Raghu Ramakrishnan, Giridhar Reddy, and Dan Syrstad. Your encouragement and
support were invaluable to me. You guys are the best!
I must also thank the talented team of developers who have contributed to the
Apache Tomcat project. This product is truly an engineering marvel, and it was an
instructive experience to rummage through its source. It is a credit to this team that
the Tomcat mailing lists are not just civil places, but are also full of interesting tips
and tricks, and well worth a visit.
Finally, I'd like to acknowledge Joginder Nahil, who provided me with an early taste
for the written word.
