基于中间件的Web服务和网格服务混合合成

随着 Web 服务和网格服务数量急剧增加，通过agent 协作的两种服务混合合成[8]却无
法解决从安全性到事务处理等问题。本文利用中间件技术，对Web 服务和网格服务混合合成框架进行了扩展；并利用面向方面的方法灵活了服务的合成。最终解决了Web 服务和网格服务混合合成中安全性、可靠性、一致性、动态性等问题。

Abstract: Those issues ranging from security to transaction in hybrid composition of Web
Services and Grid Services through agent mediation are presented while the two kinds of services are increasing. The framework of hybrid Web Service and Grid Service composition is extended by middleware technology. Service composition is made dynamic by aspect-oriented method. The problem of security, reliability, persistence, dynamics, etc. in hybrid Web Service and Grid Service composition is solved.
