I'm interested in running either the explorer from activiti 5 or the kickstart app from activiti 6 within my spring project, so that I can utilize the BPMN editing UI to modify/create processes that the activiti engine will leverage in my application. I'm confused as to how to do this. I've only be successful in running the kickstart app by running the activiti-app.war file with tomcat. Problem is I have CORS errors if I try to interact with that app's REST endpoints from my main application because it is running on spring rather than tomcat. I assume there is an easy way to run the app in spring. Anyone have any insight?
