Chapter 4. The Publisher Web Service
The Publisher web service is a demonstration of a more complex web service modeled after the one used by the SOAP Web Services Resource Center (http://www.soap-wrc.com). This service demonstrates techniques for implementing more complicated forms of web services. It builds on the Hello World example from Chapter 3.
Overview
The Publisher web service manages a database of important news items, articles, and resources that relate to SOAP and web services in general.
A Perl-based service allows registered users to post, delete, or browse items, and to manage their registration information. We've also implemented an interactive Java shell client that uses the Apache SOAP client.

Modify a user account.
- login
Start a user session.
- post

- remove
Remove an item from the database.
- browse
