Realizing a domain specific component model with JavaBeans

SaveCCM is a domain specific component model developed specifically for safety-critical hard real-time embedded systems. The goal of this paper is to extend the scope of SaveCCM to make it usable also outside this narrow domain, as the general concepts behind SaveCCM are applicable as well for embedded systems that have soft or no real-time constraints. We describe the modifications made to SaveCCM in order to adjust it to the wider scope, focusing on defining a new realization mechanism. In its original form, a SaveCCM system is realized by component allocation to real-time tasks, which means that individual components are not observable in the run-time system. We propose realizing SaveCCM by a transformation to JavaBeans, making the advantages of component-based development present also at run-time. This way we also make the executable system more general and portable.
