A Hybrid Service-based Orchestration System for Composition of Legacy Services

WSBPEL is generally accepted as a de-facto standard for Web services composition. However, WSBPEL is not a solution for integrating existing enterprise applications, such as RMI, EJB, and CORBA. In this paper, we propose a hybrid service architecture model that can describe both Web services and existing EAs as partners in WSBPEL. In other words, the suggested architecture model can represent both Web services and EAs as same type of services. We also provide a hybrid service orchestration system that supports the hybrid toolkit for automatically generating, deploying and executing hybrid services according to the hybrid service architecture model
