book was a long process As in all choices, this project had its rewards and its consequences In the end, the most important lesson I learned was one of life, not JSP I can share my thoughts in this poem I dedicate the book to anyone who takes a moment to read my poetry Days of Wonder Heaven and Hell are not after life Heaven and Hell are part of life It's in life we make our joy It's in life we build our walls To anyone who reads this may you find your own heaven may you find your own poems Break free of your chains Jump your walls Live life as if in heaven and don't make life hell We have only one life to relive over again in infinity Don't regret as you move forward Since the past is only for memories The secret to life is simply to be true to yourself and smile then you will be able to look upon each new day with the wonder it deserves It's all anyone can ever do —Casey Kochmer I dedicate this book to my family: Jim, Judy, Kristina, and my friends You have made me what I am today, and for that I thank you Life is not measured by the number of breaths we take, but by the moments that take our breath away —Erica Frandsen About the Authors Casey Kochmer is a cofounder of the JSP Insider Web site As president of AmberJack Software, Casey is a JavaServer Pages (JSP), HTML, XHTML, XML, DHTML, and Web service specialist He was previously a senior programmer, trainer, and Internet expert for Starling Consulting, where he mentored users in JavaServer Pages, Active Server Pages (ASP), XML usage, and Internet practices His job was to help customers integrate the latest technology at an appropriate time relative to the needs of a project His mantra is that a project should implement usable and maintainable technology rather than using the latest technology for technology's sake Casey codes and builds specialized applications using JSP, ASP, and various databases depending on customer needs He has coauthored several books, including Professional JSP, Second Edition and Beginning JSP Web Development Erica Frandsen is an XML, ASP, and SQL Server expert Experienced in TCP/IP networking, she is a founder of Sound Home Networks While working as a network consultant, she installs, configures, and maintains networks for clients Previously, Erica worked as a programmer and consultant for Starling Consulting, where she designed ASP and SQL systems using XML Earlier in her career, she used these same technologies to create an online tax paying system for businesses in the state of Washington She also was the Webmaster for several sites In her free
