隨著 Web 服務和網格服務數量急劇增加，通過agent 協作的兩種服務混合合成[8]卻無
法解決從安全性到事務處理等問題。本文利用中間件技術，對Web 服務和網格服務混合合成框架進行了擴展；并利用面向方面的方法靈活了服務的合成。最終解決了Web 服務和網格服務混合合成中安全性、可靠性、一致性、動態性等問題。

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.
