I was disappointed at the amount of material that it contained (it was thinner than I expected), and had hoped that it would also act as a reference to the better-known SOAP APIs, particularly Apache SOAP 2.2, ie properties and methods (much as David Flanagan's excellent "Java in a Nutshell" also includes a quick reference to the essential Java packages) - this would have made an informative book into a very useful book. Perhaps this could be considered for a second edition?
