资源说明：What You Need to Know
When we first started writing this book, we found to our surprise that one of the
hardest things was determining what to assume about you, the reader. Are you
familiar with Java? Have you done CGI or other web application programming
before? Or are you getting your feet wet with servlets? Do you understand HTTP
and HTML, or do those acronyms seem perfectly interchangeable? No matter
what experience level we imagined, it was sure to be too simplistic for some and
too advanced for others.
In the end, this book was written with the notion that it should contain predomi-
nantly original material: it could leave out exhaustive descriptions of topics and
concepts that are well described online or in other books. Scattered throughout
the text, you’ll find several references to these external sources of information.
