download
the zip version of the tutorial, unzip it, and
go to the j2eetutorial/examples directory. You cannot access the source code
in the online version of

that is available on our public web site.
How do I download The J2EE Tutorial for the Sun ONE Platform?
See the
J2EE 1.3 download page.
Note:
If you download the tutorial, feel free to make it available
locally at your site. Please do not publicly mirror
it to the Web!.
See the
next question and answer to find out why.
May I mirror the tutorial publicly?
Anyone is permitted have a copy of the online
tutorial as long as it's visible only within their own institution
(university, business, or whatever) and no one is profiting from the
tutorial's distribution.
We've taken this position because the many tutorial mirrors
mean that search engines generally
don't find the most up-to-date version of the tutorial.
Instead, search engines find mirror sites,
which invariably fall behind.
We end up getting e-mail about problems that have been
corrected in newer versions of the tutorial. Or perhaps worse, we
don't get e-mail and the reputation of the tutorial suffers. We allow
local copies because we realize that browsing java.sun.com isn't always
practical.
When you
tell us about a mirror,
we send the offender a friendly e-mail
asking them to please move their copy of the tutorial
to a place that isn't visible from the outside world.
Where can I download the Sun ONE platform software?
Sun ONE Studio 4 home page.
Sun ONE Application Server 7, Platform Edition home page.
