The current workflow nets models of WS-BPEL are feature completed, but almost all of them lack data information, so they cannot be used to detect the data access exception in WS-BPEL. In order to overcome this shortcoming, this paper presents a new type of Petri nets-DWFN(Data workflow nets), which makes the data flow modeling and exceptions detection of WS-BPEL possible. Then the DWFN model of corresponding elements in WS-BPEL and the data access exception detecting algorithm are proposed. Furthermore, we show the effectiveness of this model for checking the data access exception by an example. Overall, the research of this thesis provides effective support to the composition of Web services.
