Hi, could anyone suggest a good rules engine which works  
with Ruby? Something like Drools & Java (forward chaining).

Thanks for all your help

We had used JESS as our rule engine. I don’t know what’s the  
difference between JESS and Drools.

Another question:  
Is there any equivalent of JESS in Ruby?

Regards  
Eric
