Drools vs JBPM ? differences, pros and cons

Question

I\'m looking for a good rule engine.

I\'ve seen it exists two good projects : JBPM and Drools.

I don\'t really understand differences between the two and I don\'

Answer 1

It is not correct to say that Drools should only be used for a handful of rules. It is able to scale really well, at least at the time of this comment (version 7.5/6)

The whole point of drools and any other rules engine is the implementation of algorithms that optimize the execution of rules. Manageability of rules is proportional (if such a thing exists) to the design of the rules.

As the others have said, JBPM is not a rules engine but a workflow system that interops with drools naturally.
