The Web site for this book is http://www.ora.com/catalog/books/javanut2/. There you will find the examples from this book, available for download. As typos are reported, you may also find an errata list at that Web site.
My personal Web site is http://www.DavidFlanagan.COM/. This is a new site, just getting off the ground as this book goes to press, but it will eventually contain a number of Java programming resources, including commercial and shareware tools and "beans" that I have written.
