Abstract

This paper describes our implementation of a fact extractor for J2EE Web applications. Fact extractors are part of each reverse engineering toolset; their output is used by reverse engineering analyzers and visualizers. Our fact extractor has been implemented on top of IBM´s Websphere Application Developer (WSAD). The extractor´s schema has been defined with the Eclipse Modeling Framework (EMF) using a graphical modeling approach. The extractor extensively reuses functionality provided by WSAD, EMF, and Eclipse, and is an example of component-based development. In this paper, we show how we used this development approach to accomplish the construction of our fact extractor, which, as a result, could be realized with significantly less code and in shorter time compared to a homegrown extractor implemented from scratch. We have assessed our extractor and the produced facts with a table- based and a graph-based visualizer. Both visualizers are integrated with Eclipse.
