An Automatic Transformation From COSA Software Architecture To EJB Platform

EJB components´ communication in current implementations of EJB plate-form often suffer from unreasonable interactions overheads when the dependences among components are complex. This is because connectors are often considered to be explicit at the level of architecture and implicit in a system´s implementation. Elimination of these overheads is quite beneficial to crucial applications especially real-time ones. The explicit separation of architecture and implementation is the main concern of the Model Driven Architecture (MDA), aiming to well understanding and controlling interactions and inter-connections among components. This article defines an automatic transformation from COSA (Component Object based Software Architecture), which is software architecture model that describes systems as a collection of components and connectors, to a standard Java platform EJB using UML profiles. The goal of our work is rapid mapping and smooth integration of COSA concepts into EJB platform in order to achieve a higher level of abstraction.
