Developers who are either new to, or considering using, the Java Web Services Developer Pack will find this book to be one of the best guides to get productive in or familiar with this environment.
The book is a comprehensive examination of web services development using the JAX Pack (Java XML Pack) part of the environment, covering processing XML documents with SAX and DOM, XML transformations, using the JSP Standard Tag Library, writing SOAP clients and servers, using XML-based RPCs, web services locators, and Java SSL. In addition the book covers installing and using JWSDP tools in the Windows NT and Linux environments.
Aside from way the book provides you with a fast start, it is also exceptionally well written and laid out. I like the use of screenshots, tables and code examples that are on practically every page. These make learning the JAX part of JWSDP, as well as learning the basics of JWSDP itself, a lot easier than going through the volumes of Sun's documentation. Plus, you're stepped through developing practical artifacts, such as a SOAP client and servlets, and SAX and DOM parsers (among other useful components).
The publisher also does something I've not before seen - the book comes with a 1-year upgrade plan that provides monthly mailings and additional material when you register the book.
About half the book is about using JAX and JWSDP, and the other half is about actual development. If you are looking for a book that strictly focuses on coding and code you may not be 100% satisfied, but if you want to jump start yourself or a team this is an ideal book for that goal.
