Real-Time Specification for Java (RTSJ) is becoming a popular choice in the world of real-time programming. However, the complexities introduced by RTSJ bring needs for an extensive framework comprising all the aspects of RTSJ development. As the first contribution of this paper we present a real-time component model directly fitting the needs of RTSJ. Our motivation is to clearly separate real-time and business concerns of applications. We further argue that RTSJ concerns need to be considered at early stages of architecture design in order to mitigate the complexities of the implementation phase. Therefore, as our second contribution, we propose a design process introducing gradually RTSJ concepts into the architecture. We are thus able to alleviate the development of real-time systems and to tailor them for different real-time conditions. Finally, we demonstrate the feasibility of our solution on an example scenario.
