Beginner: Step by step tutorial?

[Winnie Leung]

HI,

I am a total beginner to Orion (and somewhat of a beginner to Java). I would
be really grateful if some one could point me to a really beginner's
step-by-step tutorial on how to write a servlet, to do standard web type
stuff like (a) post form variables, and (b) access data from the database
(oracle -- is there a way to use OCI directly, instead of JDBC?)

Thanks very much in advance,
Winnie
