摘要
基于消息的企业应用程序之间的交互越加受到关注,它主要使用发布/订阅机制实现数据(消息)的交换。但是大多数的发布/订阅通知服务均假定在同一命名空间,不支持异构空间的应用之间的数据交换。首先简要描述了用于消息的分布式异构应用程序之间的作为高层发布机制基于概念的方法,然后讨论了设计和应用该发布机制的相关问题,以及如何将该机制集成于J2EE平台的方法。
Enterprise application interactions based on events have been receiving increasing attention. It is based on the exchange of small pieces of clam （called events） typically using the publish/subscribe mechanism. Most pub/sub notification services assume a homogeneous namespace and do not support the interaction among heterogeneous event producers and consumers. This paper briefly describes the concept - based approach as a high - level dissemination mechanism for distributed and heterogeneous event - based application. It focuses on the design and implementation issues of such a mechanism and shows how it can be integrated on research J2EE platforms.
