Most common among these are logging, authentication, authorization, and persistence. Cross-cutting concerns always cause program code to be scattered and tangled, and therefore make it harder to understand and maintain. Similar problem also occurs in the field of workflow. In our research, we apply the concept of aspect-oriented programming(AOP) to the field of workflow system, and implement a static weaver for jBPM. With static weaver, process designer can use the facilities of AOP, and the performance is also improved via static weaving .
