Rapid Development of Composite Applications Using Annotated Web Services

摘要

Developing service-based interactive applications is time consuming and nontrivial. Annotating web services with additional information about the user interface and behavior of the service promises to ease and accelerate the development process. In this paper we present a model-driven development approach that utilizes the advantages of annotated web services during the service composition. It enables a rapid development of simple service-based applications in a graphical manner. Besides the description of the process and the models, our current service composition tool implementation, the "ServFace Builder" is introduced. The ServFace Builder infers graphical UIs from functional interface descriptions such as WSDL files which then can be combined in a presentation-oriented way to a service-based interactive application.
