%X OSGi specifications provide dynamic services management framework, but there arc no real-time criterion and detailed solutions on the specifications. This paper presented a solution of providing a dynamic real-time framework for deploying the real-time components and services by integrating RTSJ into OSGi. This paper first analyzed the impact of RTSJ on the OSGi framework, and then for the reason that the existing OSGi event mechanism in the RTSJ can not satisfy the real-time computing rectuirements, provided a new event mechanism solution based on the RTSJ real-time threads. It resolves the problem of real-time switching between the services in the RTSJ-based OSGi framework and ensures OSGi based time predictability of real-time embedded systems in the dynamic environment.
