XML Development with Java 2

Michael C. Daconta is President of Synergy Solutions, Inc. where he develops advanced systems with Java, JavaScript and XML. Additionally, Mr. Daconta trains introductory and advanced courses in numerous web technologies. He is a Sun-certified Java Programmer who has been developing software for 16 years. He co-authored Java Pitfalls and Java 2 and JavaScript for C and C++ Programmers and authored C++ Pointers and Dynamic Memory Management. Albert J. Saganich is a Principal Technologist with BEA Systems Inc. where he develops, trains, and mentors on Java, XML and related Internet technologies. Al is currently responsible for developing and maintaining the BEA WebLogic Server training curriculum and presents training materials whenever he can. Al has been involved with software development for almost 15 years and has co-authored The Java 2 and JavaScript for C and C++ Programmers (with Mike C, Daconta) as well as The Microsoft Visual J++ SourceBook (with Jay Cross). In his spare time Al writes Java, C++ and XML based articles.
