WebDynpro Navigation & Component-Orientation

WebDynpro is SAP’s new approach for web application development. Developers are supposed to create their applications with visual tools that require little knowledge concerning implementation details. Hence, most of the source code is generated by the used development environment. The WebDynpro approach allows developers to separate presentation- and business-logic. In addition, WebDynpro Applications are operating system independent. Developers can create WebDynpro Applications using either ABAP- or Java-technology.

This paper aims to describe opportunities provided by WebDynpro technology regarding front-end design, navigation logic and reusability. Besides, it focuses on the Java-personality of the SAP Web Application Server and, therefore, deals with the Netweaver Development Studio regarding application design. Read more
