[rules-users] Getting hold of the Evaluator Registry

[Edson Tirelli]

   I am working in one example of drools features where I implement a custom
evaluator here:

http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/lotrc/src/main/java/org/drools/examples/lotrc/evaluators/IsAdjacentToEvaluatorDefinition.java

   I use the configuration file instead of API in the example:

http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/lotrc/src/main/resources/META-INF/drools.packagebuilder.conf
