A Web Services Composition With Well Structured

Abstract

This paper proposes a Web services composition approach. Using this approach, the composition planner can deal with succession, conjunction and exclusion control structures. Moreover, the composition plan is dead lock free and can terminate normally (which is defined as well structured). In this paper, along with a declarative definition of basic concepts and description of candidate Web services, the composition approach gives an algorithm to generate the composition plan and an aggregation of control structures among the candidate Web services. Furthermore, the case study illustrates that the composition plan using proposed approach is dead lock free and can terminate normally.
