I am currently reading the book Web-Services by Richard Monson Haefel .
Note that this book is somewhat dated; for example, it covers JAX-RPC (which is obsolete) but not JAX-WS (JAX-RPC'S successor). If you're specifically interested in developing
Java SOAP web services, then the
Mark Hansen book would make for good follow-up reading.
But both books are mainly about SOAP, whereas these days REST is very popular as well. The
WebServicesFaq has various links to introductory material about both these architectural styles.
The Java Web Services Tutorial
The JWSDP 1.6 is seriously outdated; don't use that (and, by corollary, don't read this tutorial).
