JEOPS -- the Java embedded object production system Although the concept of intelligent agents facilitates the development of systems which require intelligent behavior, the lack of standard tools to support the creation of agents is still an obstacle for the broad use of this paradigm. Agents can be created via the use of either specialized languages or general-purpose ones. We claim that the latter is more suitable for complex applications where components reuse is highly demanded. In this case, the integration of production rules and objects is a promising approach. This article presents JEOPS, an inference engine that aims to provide reasoning capabilities to Java. JEOPS gives a special attention to the problem of the rule-object integration uniformity, because of its impact on the system reusability and readability. JEOPS has been used in different projects, and the results are very encouraging.
