Dear All, I discovered why the rules stopped working after ChangeScanner starts the problem is the issue JBRULES-2947<https://issues.jboss.org/browse/JBRULES-2947?page=com.atl... . To fix the problem I changed my models to a POJO package instead of the Described in the Guvnor (the solution was found in this thread http://drools.46999.n3.nabble.com/drools-server-resource-change-scanner-n...), after that when I start the Change Scanner by the jsp DroolsServer detects changes in the rules stored in Guvnor, and fire all rules properly. The unique problem that persists is the Change Scanner start that i need to call it in the JSP mannually, I'll automate in the the application start.
