I enjoy hearing from readers, whether with general comments about this book, specific corrections, other topics you would like to see covered, or just war stories about your own network programming travails. You can reach me by sending email to http://www.cafeaulait.org/books/jnp3/ and on the O'Reilly web site at http://www.oreilly.com/catalog/javanetwk/errata/. Before reporting errors, please check one of those pages to see if I already know about it and have posted a fix. Any errors that are reported will be fixed in future printings.
