Approach of Graphic BPEL Workflow Debugging

This paper focuses on designing a remote graphical debugging process mechanism. With this debugging process mechanism, users can debug the BPEL process in the graphical interface, set breakpoints on the active graphical elements; using single-step operation, resume operation and suspend operation in the interface. By the remote interaction with workflow engine, users can look up the execution of the process in a convenient and intuitive graphical view, track the execution path and attain the variables´ information in the process running period. Users are also allowed to correct the processes´ error, which helps to verify the correctness of the workflow.
