I discovered a short time ago that another author wrote a (much shorter) book called SOA Cookbook in the same time frame I did, for Packt publishing. Our books turn out to be wildly different (I'm not quite sure how his counts as a cookbook). But because that book was released in the last few weeks, and mine just went to production yesterday, I was forced to change my title.
The good people at O'Reilly banged it around for a while. We tried SOA Cookbook for Java Developers, SOA and Web Services Cookbook, and some variations like that. We came up eventually with Java SOA Cookbook. So that's the new title. The book will be in the Java domain for O'Reilly, meaning that it will have a purple spine (not the blue/green of the XML line as we originally thought).
Michael Havey's SOA Cookbook, in any case, covers entirely different material than my book, and is very focused on BPM and creating processes within TIBCO's tools. In general, I agree with the proposition that Process Oriented Architecture is a key element of SOA, or a variation on the theme.
So if you've been looking for my book, it's now Java SOA Cookbook, and will be in stores in early March.
