Consulting past exceptions to facilitate workflow exception handling
In this paper, we propose an architecture model that deals with both expected and unexpected exceptions in the context of workflow management. Expected exceptions and their handling approaches are specified by ECA rules, while cases of unexpected exceptions are characterized by their features and resolution approaches. The handling of unexpected exceptions is then assisted by the system providi...
متن کاملException Handling in Web Service Processes
Cross-company business processes are common in today’s networked economy and are nowadays often supported by process support systems that integrate the information systems of the different partners based on web service technology. In contrast to earlier Workflow Management Systems, which were often deployed in the controlled environment of a single company, the distributed nature of modern solu...
متن کاملRefactoring Idiomatic Exception Handling in C++: Throwing and Catching Exceptions with Aspects
Aspect-oriented programming can be used to modularize crosscutting concerns to improve the maintainability of large systems. Exceptions cross-cut legacy applications and are often implemented in idioms which cannot be globally enforced. We describe an aspect-oriented approach for throwing exceptions in place of the “return code idiom”, and discuss using aspects to handle those exceptions in a m...
متن کاملA knowledge-based approach for handling exceptions in business processes
This paper describes a novel knowledge-based methodology and toolset for helping business process designers and participants better manage exceptions (unexpected deviations from an ideal sequence of events caused by design errors, resource failures, requirement changes, etc.) that can occur during the enactment of a process. This approach is based on an on-line repository exploiting a generic a...
متن کاملHandling Exceptions in Haskell
Using a language without exception handling is like driving a car with no brakes and no seatbelt | things work ne until something goes wrong. You also learn to drive rather carefully. This paper describes an exception handling extension to the Haskell lazy functional language. The implementation turned out to be very easy but we had problems nding a viable semantics for our system. The resultin...
