Abstract. Web Service orchestration frameworks support a coarse-grained kind
of exception handling because they cannot identify the causes of the occurring
exceptions as precisely as needed to solve problems at their origin.

ploys diagnostic services to support a fine grained identification of the causes of
the exceptions and the consequent execution of effective exception handlers. Our
framework is particularly suitable for intelligent exception handling in Enterprise
Application Integration.

execution of tasks within a single organization.Later on, Service Oriented Architectures
