About the Author
Bernard Van Haecke leads the Sun Java Center in Belgium and Luxembourg, a Sun Professional Services consulting practice where he helps customers build and implement complex software applications based on Java and J2EE. He focused on Java since the day it was made publicly available by Sun in May 1995 and started writing one of the first books on JDBC for IDG Books Worldwide (now Hungry Minds) the next year. He then leveraged many of the new APIs, including enterprise APIs, in customer projects for more than half a decade, which led to the development of an avant-garde E-banking and E-trading system in 1997, the re-architecture of IT environments in financial institutions centered on new paradigms, the realization of numerous Java pilots in various fields of the industry, and several coaching and mentoring missions.

I also want to thank all the great people at Sun who make Java, JDBC, J2EE, Jini, etc. so cool, and all my colleagues who turn these into real successes when designing and building systems for customers. Special thanks to Stu Stern, VP Worldwide Sun Java Centers, and Staffan Calais, manager of Sun Java Centers Northern Europe, for leading these efforts!
