Now I am able to load rules applying change set with<br />KnowledgeAgent (thank you!!!), but honestly this is a poor success because,<br />even if when I change the rule KnowledgeAgent says "incremental build of<br />KnowledgeBase finished and in use" nothing changes. <br />It seems that changes at rules have no effect and it is pretty weird. I made<br />a maven project with eclipse to explain you better my problem. Is a simple<br />main. I am working for a better junit test.
