The recent evolution of mobile smart devices and their convergence with pervasive computing and software as a service raises new challenges. Developers of applications targeted to these environments have to face at least three major challenges: dynamicity, heterogeneity, and distribution. In this paper, we propose a service oriented component framework which addresses these challenges by automatically reifying available services in a distributed pervasive environment. Therefore, the only thing developers have to focus on is writing the business code. We have implemented and validated our framework by using several real applications developed within collaborative projects (including ITEA ANSO project).
