Abstract

Web Services Business Process Execution Language (WS-BPEL) provides the language to specify business processes that are composed of Web services as well as exposed as Web services. In business processes and during service invocation, errors may occur from latent faults, e.g. partner services may not be available or not respond within time.[1] We want to have reliable business processes hence we need to have reliable web services. To have reliable web services fault occurrences should be prevented. Objective of this paper is to present an architecture which ensures more reliable composed services. Therefore we propose an architecture which dynamically detect and recover failures using software fault tolerance patterns and mapping them to WS-BPEL .finally a Business Process is designed To implement attained proposition.

Keywords: WS-BPEL, Fault Tolerance Pattern, Web Services
