OnJava has published an article about how to implement message oriented web services in Apache Axis2. The title of the article is “Web Services Messaging with Apache Axis2: Concepts and Techniques” and it is written by Srinath Perera and Ajith Ranabahu (both Axis2 developers).
I believe that the above article is very interesting since it provides an introduction to both messaging and the API of the new version of Axis.
