It's true that you should read the documentation.  As a former newbie
and teacher, though, I appreciate the need for some helpful hints:

JPA is Java's Persistence (Saving) API found in the
javax.persistence.* package.  You can use JDO as an alternative,
though, instead of JPA.  I would recommend this simply because Google
App Engine has better documentation for JDO.  In the end, to the new
user, they are essentially the same.

JPA or JDO is how you will save full Java objects into the Google
database.  It is not difficult to make the database connection if you
follow the tutorials.  At this stage, it sounds like you will have
more trouble creating a basic web application.  So, I would start with
that first - also in the tutorials.  The App Engine SDK comes with a
few sample projects that should work out of the box - see if you can
get those up and running.

Good luck!
