Abstract
The construction of distributed applications is a challenging task due to inherent system properties like message passing and concurrency. Current technology trends further increase the necessity for novel software concepts that help dealing with these issues. An analysis of existing software paradigms has revealed that each of them has its specific strengths and weaknesses but none fits all the needs. On basis of this evaluation in this paper a new approach called active components is proposed. Active components are a consolidation of the agent paradigm, combining it with advantageous concepts of other types of software components. Active components, like agents, are autonomous with respect to their execution. Like software components, they are managed entities, which exhibit clear interfaces making their functionality explicit. The approach considerably broadens the scope of applications that can be built as heterogeneous component types, e.g. agents and workflows, can be used in the same application without interoperability problems and with a shared toolset at hand for development, runtime monitoring and debugging. The paper devises main characteristics of active components and highlights a system architecture and its implementation in the Jadex Active Component infrastructure. The usefulness of the approach is further explained with an example use case, which shows how a workflow management system can be built on top of the existing infrastructure.
