This article is by editor Linda Vergon. Is there a bill you pay that you absolutely detest? Occasionally, I’ll get an attitude about paying one bill or another. (Ha! Paying taxes on April 15 is one bill that comes to mind immediately, for example.) I recognize that there is a… read more

Hudson Twitter Plugin 0.2 Released

"If you need to know a lot about the use of XML in Java (and who doesn't need that), the book gives you the needed information. Sometimes it was a bit boring, because of the wealth of given generalized toolkits. But if I use one of those toolkits, I know where I can get relevant information about it. I recommend it more as a book of references, than a book you should read from start to finish."
--Bart Vrancken, JavaLobby

"Are you developing with Java and need to use XML? If you are, then this book is for you. Authors Brett McLaughlin and Justin Edelson, have done an outstanding job of writing a book that that cuts through all of the hype about XML and put it to work...This most excellent book shows you how to use the APIs, tools, and tricks of XML to build real world applications. Perhaps more importantly, this book offers a new approach to managing information that touches everything from configuration files to web sites."
