Abstract. This paper proposes a framework based on Service Oriented Architec-
ture 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 prob-
lem without modifying the basic mechanism offered by standard orchestration
engines such as the WS-BPEL compliant ones.
