Hi, Thanks for taking the time to reply. I just got my MySQL cookbook in the mail (has a JSP section) and combined with an O'Reilly JSP book I'm going to try to tough it out over the Thanksgiving holiday. I have less documentation on your approach and it looks like even more to learn (Ant for instance); I'm really a hardware guy who likes to play with software ;-}, I have better luck with assembler on 8 bit micros. The JSP book is by Bergsten and he really doesn't go into the web.xml file much, I think I will attack that first.
