Résumé : OSGi is a pragmatic wrapper above the Java Virtual Machine that embraces two concepts: the component approach and service-oriented programming. The component approach enables a Java run-time to host many concurrent applications, while the service-oriented programming paradigm allows the decomposition of applications into independent units that are dynamically bound at runtime. Combining component and service-oriented programming greatly simplies the implementation of highly-adaptive, constantly-evolving applications. OSGi particularly ts ambient requirements and constraints by absorbing and adapting to changes associated with context evolution. This paper summarizes our INRIA Amazones1 team work on extending OSGi specications and implementations to cope with ambient concerns. This paper references our OSGi extension publications divided by three main concerns: management, isolation and security.
