Hello,

I’m trying to add a custom event listener to flowable-task app and I cannot find any hints on how to do it in docs.  
Simply adding a jar to the lib folder obviously does not work, flowable-ui-app.properties file where I configure engine stuff like database connection doesn’t have any hints on where should I mention the event listener.

Does anyone have any idea on how it is done? I recall for Activiti 5 I’ve managed to do it by adding some custom configuration classes to a jar with the event listener, does Flowable have any way to do it?

Hey @lossril,

[Custom Bean deployment for Task/Rest App](https://forum.flowable.org/t/custom-bean-deployment-for-task-rest-app/2813/2?u=filiphr) is similar to what you are trying to do. You need to register the event listener through the `ProcessEngineConfiguration` and you can do that by making your class an auto configuration.

Cheers,  
Filip
