This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
I do not think this tutorial is new. It is several months old. Addison-Wesley has a book of the same name which is basically a printed version of this tutorial. I do not think this tutorial is terriblly useful. It contains a lot of different (but rather basic) stuff. Any information with regard to tools in the JWSDP package is buried deep in the tutorial. I personally find Deitel's "Java Web Services for experienced programmers" by Prentice Hall a better book.
