This paper presents a process for the development of a Model-Driven Architecture (MDA) tool for the construction of service-oriented component-based applications. The process is used in the construction of a tool for one particular domain, but can be easily adapted to other domains. The tool in itself simplifies the development of components using a MDA approach, in which modeling is at the core of the development activities. After components are modeled, the tool validates the correctness of
