An Exception Analyzing and Handling Approach of Composite Service Based on ECA Rule

Exception handling is an important issue in service composition domain, and its mechanism should be considered in the service composition process. When invoking the composite service, exception handling involves with not only process design and status, but also service execution status. This paper proposes a context-sensitive ECA Rule based approach to analyze composite service exception (ANALEPTIC), which can select flexible handling policy according to analysis of exception situation. The approach efficiently considers the process exception and the execution status of relevant actions. The matching algorithm wraps the exception handling policy to service, through which the exception situation is actually handled. As a result, complex exception situation can be effectively handled.
