When is your Head First for SCDJWS going to be released in the stores? I am dying to get a copy of that. After reading the Head First series, I dont feel like reading any book. You make the concepts so easy to learn.
Looking at www.headfirstlabs.com, no such title seems to be in the works. It probably wouldn't make sense to write it right now, since the SCDJWS content is kind of outdated. Everyone's expecting a new version of the exam to come out at some point.

A significant problem with the SCDJWS is that the subject matter doesn't begin to cover the integration space. So the certification tells you that the holder has a decent knowledge of the legalities of the various JAX technologies, but not whether they know about other kinds of integration methods.
In the real world a lot of this is done using vendor tools (Oracle, Websphere, and Weblogic come to mind) or using a relatively new set of open source projects such as Apache Servicemix, Mule, Apache Synapse, and supporting open source projects which each solve a portion of the problem domain. Unfortunately SCDJWS tells you nothing about these areas.
I'm probably going to go get the SCDJWS anyway next year, to add some documentation to my CV and to tighten my knowledge of the formal WS specification. But I don't expect a certification book to come out any time soon, so what I'll probably do is rely on specifications, exam notes, and purchase one of the SCDJWS test simulators on the market for the all-important exam practice.
