Java 2 Enterprise Edition (J2EE) Web Component Developer Exam Cram 2 (Exam Cram 310-080)

Alain Trottier observes the .com warfare of Southern California as a technology management consultant (Strategic Business Resources) and an adjunct professor at Vanguard University. He has been in the tech sector for two decades. On the electronics side, he has worked with RF gear, nuclear power plants, and electromechanical devices. On the IT side, he has held roles as a technologist, a developer support specialist, a programmer, an architect, and a manager. Alain got a kick out of being in the U.S. Submarine Navy (nuclear power division), and he was impressed with his bosses at Chevron's world-class research center. He was astonished by the .com bubble while at Adforce and then Winfire, where he experienced a meteoric IPO and then a subsequent flameout. He has been through a get-it-right-at-all-cost experience in a Fortune 30 company, and he also has witnessed the other extreme, in which one bets it all on a get-it-out-there-at-no-cost venture. Alain enjoys a difficult technological challenge and likes the people even better. He believes that his degrees in religion (Bachelor of Arts, Master of Arts with a specialization in the linguistics of ancient religious texts) is a terrific way to broaden one's abilities. He has certifications from both Microsoft and Sun, so his bias is simply what works best for a given situation. If you have a question, comment, or even a challenge, the author would be delighted to hear from you.
