Hi everyone! 

we have made other tow tests:

1 - As suggested by Vincent, we have just used the source gets from Guvnor and all work fine.

In addition, it would seem that putting observations and events in the same package all work fine!!!

2 -  We have tried to put the observation in the same packet of event in the model and the new drl becomes:

from package org.dfms.model; to package org.dfms.model.situation;

from import org.dfms.model.observation.ACObservation; to import org.dfms.model.situation.ACObservation;

import org.dfms.model.situation.AccessControlEvent;

import org.dfms.model.situation.SituationManager;

import org.dfms.model.situation.Event;

import org.dfms.model.mapfeature.AccessControlPoint;

import com.vividsolutions.jts.geom.Point;

import com.vividsolutions.jts.geom.Geometry;

import java.util.HashSet;

import java.util.ArrayList;

declare ACObservation

      @role(event)

end

declare AccessControlEvent

      @role(event)

end

rule "AccessControl"

      no-loop

      when

            $obs  : ACObservation( $sensorid : sensorId, $location : location ) over window:length(1) from entry-point access_control

      then

            insert( SituationManager.createAccessControlEvent( $obs, "Access Control Detection", Event.THREAT_NO, $location, $sensorid ));

end

then we have loaded the pkg from Guvnor (by this link

http://localhost:8080/guvnor/org.drools.guvnor.Guvnor/package/org.dfms.model/LATEST)

into our application and all work fine!!!

Thank you and best regards.
