We are using onespan integration in Guidewire 8.0.7 version and I was able to create the package in my local environment . we promoted our code to the one of testing environment. When we click save draft package button on the onespanpackagepopupscreen we are getting the NoClassDefFoundError: gw/accelerators/onespan/OneSpanJSONUtils exception. We tried different ways to resolve this issue but none of them worked. We really have no clue why this class is not being able to recognized by the compiler at runtime.
