Integrating Drools Rule Engine to Camunda process

BPMN & Modeling Discussion & Questions
1

I have modeled a BPMN with business rule task, wherein I can use camunda DMN itself, but we are already using JBoss Drools Expert rule engine.

So how to integrate the JBoss rule engine with camunda, and how can we set a decision outcome to the camunda resultvariable?

Hi
Disclaimer: Im not a Drools user! - However, I would probably look at wrapping the Drools engine in a class which I could delegate to. Thus you could use the equivalent of a service task. Hence the engine hands control to your wrapper class, you package up variables, call drools as a library, re-package the result.

Note you can still use the BPMN rule task here as you can select a java class as the implementation mechanism.
