Query: actually a really helpful book

As a developer, I've read several titles on SOAP and web-services - and found most to be too 'architectural' (view from the top - v. little hands-on, detailed understanding). While SOAs and web services architecture are all fascinating - when one gets down to the development - one needs a thorough understanding of SOAP - its various implementations - and current stumbling points.This book provides all of the above for 'java' soap (it was written prior to Axis release - but still contains enough useful information). For .NET soap - I use OReilly's Programming .NET web services - which is also excellent. I have no complaints about this book - I got what I needed from a developer's perspective and also some from an architectural perspective (for e.g. - the author illustrates how using JMS with SOAP provides a truly resilient and flexible SOA).
