What in your mind make are the desirable attributes for a "good book for developing J2EE web services".
Currently the standard for J2EE (as opposed to "Java Web Services") is
J2EE Web Services (Richard Monson-Haefel; RMH). But that is not everybody�s cup of tea.
Otherwise have a look through
The Bunkhouse: Web Services and SOAP � you may find something that you like.
This one might be worth a look if you are (also) interested in "Java Web Services" - i.e. Web Services implemented in
Java without being entirely bound to the J2EE specifications (and no EJB endpoints; though in most cases that isn't a real loss):
