Hi,  
How can I use IDM engine with MongoDB datasource along with Flowable Engine.  
I enabled the IDM engine in the below code and getting the following error: _ **A datasource is required for initializing the IDM engine** _

ProcessEngine processEngine = new MongoDbProcessEngineConfiguration()  
.setServerAddresses(Arrays.asList(new ServerAddress(“localhost”, 27017)))  
**.setDisableIdmEngine(false)**  
.buildProcessEngine();

Please let me know how to set MongoDB datasource in order to use IDM Engine

Thanks in advance,  
Venkat PS

AFAIK MongoDB support for datasource is at an alpha stage:

Hi mykeul, Yes, this module is working for other services of flowable except for IDM service.

That’s currently not yet implemented. The MongoDB integration is a prototype, to prove it’s possible with Flowable. However, so far we haven’t seen a large demand/uptake for it.
