Enhancing web service composition by means of diagnosis

Abstract

This paper proposes a framework based on Service Oriented Architecture which integrates diagnostic services in the architecture of a composite service in order to improve the recovery from the occurring exceptions. Our framework supports a fine-grained selection of exception handlers suitable to repair the problem without modifying the basic mechanism offered by standard orchestration engines such as the WS-BPEL compliant ones. © 2009 Springer Berlin Heidelberg.
