No, I did not write Java Lotus Notes ...just Java Notes :-)
It is great little website for anyone who is using Java or want to use Java.
Really useful, packed with examples and code snippets.

Another great site is of course "Java Developers Almanac". It contains all the code samples from the book and more.
It is java 1.4, but it is still very good and packed with great examples.

(the site has been updated with new layout and features I see)
