Failures during Web service execution may depend on a wide variety of causes. In this talk we propose a classification of Web service faults, discussing three levels of faults, namely infrastructural and middleware, Web service, and Web application, and their mutual dependencies. In order to add self-healing capabilities to Web service environments, possible recovery actions at the Web service and Web application levels are illustrated and discussed with respect to a running example involving coordinated Web services.
