In this paper we introduce a new modeling tool for constraint handling in the area of workflow technology. The constraint handlers can be used to improve the quality of business processes but without changing already existing business logic. Todays workflow languages provide no possibility to model constraints and the actions in case the constraints get violated explicitly. Fault and event handling...
Assessing the quality of tests for BPEL processes is a difficult task in projects following SOA principles. Since insufficient testing can lead to unforeseen defects that can be extremely costly in complex and mission critical environments, this problem needs to be addressed. By using formally defined test metrics that can be evaluated automatically by using an extension to the BPELUnit testing framework,...
AO4BPEL applied Aspect Oriented Programming to executable business processes. Although modularized, AO4BPEL aspects do not have an explicit interface and the implicit one, based on XPath, is often fragile, hence reusing aspects in different processes is quite hard. Cooperative Aspect Oriented Programming aims at making aspects reusable by means of cooperative work between base code and aspects, realized...
