Towards a contract aware CORBA component container

Component based software engineering (CBSE) suggests the idea of applications as assemblies of prefabricated components. Practical experiences with the CORBA component model (CCM), which is a multi-language and multi-platform component architecture, have shown that pure syntax declarations are inadequate for describing trustworthy software components, in particular for reuse. In this paper we present a contract extension to the CCM metamodel, a contract aware CCM container that improves the trustworthiness of CORBA components and experimental results that explore the runtime impacts of contract verification.
