If you do a search on this forum you'll probably find quite a few. Some of the ones that I've read are Steve Graham's book which is truly excellent overall, Bill Brogden's book which covers a lot of different features of Web Services on many platforms, and James Snell's book which has good coverage of some obscure topics like the details of SOAP encoding[/URL].

Webservices tutorial offered by Sun only teaches API that can be used to create, access and publish webservices. There are two problems here,  What if you are using a SOAP engine (such as apache axis) and it does not implement all the APIs completely (for example, axis uses its own Service and Call objects rather than the ones from xml-rpc APIs)  APIs are not enough to create webservices. Which toolkit (IBM or axis) or app server (WAS, Oracle, WEblogic) should be used with the tutorial. In other words, who implements these APIs?
