Todays information systems are built using various component models such as Enterprise Java Beans, JavaBeans, Microsoft COM+, and CORBA distributed objects. In this paper we argue that it is crucial for designers of information systems to interactively build and test systems constructed from (a) components (enabling interoperability across component models) and (b) Web services at the same time. The contribution of this paper is threefold: Firstly, we introduce a visual tool the Component Workbench – for designing information systems out of components from different component models (e.g. EJB, COM+, CORBA) and combine them with Web services. Secondly, we show how component compositions can be turned into Web services using SOAP as a communications protocol. Thirdly, we show how to interactively test compositions before creating the actual Web services out of components.
