<br> Yes, you are in the right track, and I understand this is a bit confusing at first. One more reason for people to go to the October Rules Fest 2009 where I will give a presentation on all the ways to extend the engine to solve specific problems. It will be interesting I hope (last year was awesome) and even Charles Forgy will be there doing a presentation on Parallel Rete. :)<br>
<br> Meanwhile I will write a tutorial on this, but just to help you there, your approach is correct, except that you don't need to setup the option for each operator. It works like this:<br><br>* One EvaluatorDefinition class implements support to one or more evaluators, defined by the method public String[] getEvaluatorIds().<br>
<br>* All you need to do, then, is wire you class once and the engine will pick-up all the IDs supported by that class. When you have your class wired, you give it a unique string identifier, so that if you ever need to replace it, or remove it, you will use that id. Sometimes we use the operator as the ID, but usually it is something that reminds you of the kind of evaluators that class define. For instance, drools registers the ComparableEvaluatorsDefinition in this way:<br>
<br>drools.evaluator.comparable = org.drools.base.evaluators.ComparableEvaluatorsDefinition<br><br> So in this case, "comparable" is the identifier. Finally, from my previous e-mail you will see that the reason that the eclipse IDE is still giving you errors is that you are using the API to configure the evaluators. Just move the configuration to the configuration file and the IDE will pick it up.<br>

<br>
My recommendation is create a new operator for you instead of
overriding existing ones. Although if you really want to replace the existing
ones, setting the property or calling the API to register a new operator will
override the default.<br>
