I have developed a web application that uses Activiti engine for different treatments on my workflows. However I was asked to use a dropwizard in order not to work directly on the engine, but to circulate exchanges between the engine and my webapp through the dropwizard. As I didn't know how to use a dropwizard, I followed this tutorial: https://dropwizard.github.io/dropwizard/getting-started.html The communication between my webapp and my dropwizard doesn't have any problem, but I can't find how to establish communication between my dropwizard and Activiti engine. Does anyone else have this problem?
