Dynamically Adaptable Applications with iPOJO Service Components

摘要

Traditional component models and frameworks simplified software system development by enabling developers to break software systems into independent pieces with well-defined interfaces. This approach led to looser coupling among the system pieces and enhanced possibilities for reuse. While the component-based approach led to advancements in the software development process, it still has its limitations. In particular, after a component-based application is developed and deployed it typically is a monolithic and static configuration of components. The advent of service-oriented component (SOC), the rise in popularity of consumer devices, and the ubiquity of connectivity have fostered a growing interest in applications that react dynamically to changes in the availability of various services. To simplify the creation of such dynamic software systems, it is possible to borrow concepts from SOC and include them into a component model, resulting in a service-oriented component model that specifically supports dynamically adaptable applications. This paper presents iPOJO, a service-oriented component framework to help developers implement dynamically adaptable software systems.
