Tutorial: Creating an E-Mail Client Using Web Dynpro's Adaptive Web Service Model
In this tutorial, you will develop a Web Dynpro application for sending an e-mail message, using an e-mail Web service provided by an external service provider. It fully describes all required development steps like setting up a new project, importing the Adaptive Web Service Model, defining context mapping and binding relations, designing the view layout and implementing the controller code.
Use of the e-mail Web service is enabled by an appropriate Adaptive Web Service model generated by the Web Dynpro tools. The quick implementation of this Web Dynpro application is characterized by a highly declarative development process, in which the required implementation workload can be reduced to a few lines of Java code.

Article: Adaptive Web Service Model Controller Coding Explained
Note: This article is an addition to the tutorial Creating an E–Mail Client Using Web Dynpro's Adaptive Web Service Model above comprising an in-depth description of the coding-specific technical details. Please read the introductory tutorial first to understand the Adaptive Web Service Model principles. Both, tutorial and article, are based on the same Web Dynpro sample application.
This article de-mystifies the magic relationship between a Web Dynpro model and a Web Dynpro controller context at runtime, so that you really understand how to correctly implement the model-specific controller code within your own Web Dynpro applications: how to instantiate model objects, how to create a model object graph, how to bind executable model objects to a context node, what’s going on technically when executing a model object and why to invoke the IWDNode.invalidate() method of the response context node object.
In addition to these principle aspects this article describes some technical details which are specific for the Adaptive Web Service Model like tracing Web Service invocations and programmatically modifying Web Service invocation settings with the IWDWSInvocationModifier-API and the Service Extenstion Interfaces of the Web Service Runtime.

SDN Wiki Page: Web Dynpro Java FAQs - Models - Adaptive Web Service
The Adaptive Web Service Model topic is a perfect candidate for the SDN Wiki. I'm totally convinced that the collaborative Wiki approach yields many advantages for technical knowledge transfer compared to the former PDF- or WebLog-based approach: easy content editing, rapid update, code formating, collaborative editing, comment support, label/tagging support and much more Web 2.0 like features. Together with my colleague Patric Ksinsik I therefor created a specific SDN Wiki page comprising lots of in-depth information on the Adaptive Web Service Model:
FAQ - Models - Adaptive Web Service.
