Sure.

This is the one that I got started with when it first came out.

Ok, it's getting at the data from your JSP that causes so much grief for
people. Either you write the code in the JSP to call getAttribute on the
session/request objects *or* you come up with some custom tags to do that
for you.
Whether it goes into the session or request context (or application
context) really depends on how long the data should live. For the most
part you will be using the request context to pass data from your servlet
to jsp.

Well, I suspect you'll be doing forward() a lot more than you will be
doing include().
Check out the specs (both servlet and JSP) - a quick grep for
setAttribute, getAttribute and RequestDispatcher ought to be enough info.
