Environment: Eclipse Indigo, Drools Core,Guvnor,Task 5.2.1.Final, Spring MVC 3.x How would one do Debug As Drools Application in this scenario to hit a break point in the drl file? You get a a big list of Crap from Eclipse where my drools app is not even listed although I performed the Drools app conversion. Eclipse looks for Main method but this is a Spring MVC app.
