For jBPM6, integration with the Drools rule engine happens seamlessly. The process en-
gine
is
in fact a rule engine as they are both running on the same environment. This allows
you to handle complex stateful scenarios with ease using rules, from simple validations to
handling process activity monitoring and decision management based on rules. Every pro-
cess instance that is running in the same KIE session will share the same rule-based
memory, state, and data, and have special rules to determine situations that cross-reference
many different process instances. This would be impossible to do in a stateless environ-
ment where each process instance would be completely isolated from other executions.
With those functionalities running for us, we can create smarter and more flexible pro-
cesses that at the same time are easier to read, thanks to being able to take all complex de-
cisions using rules. This means that we need to only worry about the sequence of activit-
ies from the process's perspective.
