When I wrote the preface to the first edition of Java & XML just over a year ago, I had no idea what I was getting into. I made jokes about XML appearing on hats and t-shirts; yet as I sit writing this, I'm wearing a t-shirt with "XML" emblazoned across it, and yes, I have a hat with XML on it also (in fact, I have two!). So, the promise of XML has been recognized, without any doubt. And that's good.
However, it has meant that more development is occurring every day, and the XML landscape is growing at a pace I never anticipated, even in my wildest dreams. While that's great for XML, it has made looking back at the first edition of this book somewhat depressing; why is everything so out of date? I talked about SAX 2.0, and DOM Level 2 as twinklings in eyes. They are now industry standard. I introduced JDOM, and now it's in JSR (Sun's JavaFigure 0 Specification Request process). I hadn't even looked at SOAP, UDDI, WSDL, and XML data binding. They take up three chapters in this edition! Things have changed, to say the least.
If you're even remotely suspicious that you may have to work with XML in the next few months, this book can help. And if you've got the first edition lying somewhere on your desk at work right now, I invite you to browse the new one; I think you'll see that this book is still important to you. I've thrown out all the excessive descriptions of basic concepts, condensed the basic XML material into a single chapter, and rewritten nearly every example; I've also added many new examples and chapters. In other words, I tried to make this an in-depth technical book with lots of grit. It will take you beginners a little longer, as I do less handholding, but you'll find the knowledge to be gained much greater.
