Re: [rules-users] java.lang.NullPointerException at org.drools.reteoo.ReteooFactHandleFactory.newFactHandle(ReteooFactHandleFactory.java:56)
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!!!

Hello, I made another test. I downloaded the source URL for package source: http://localhost:8080/guvnor/rest/packages/org.dfms.model/source from Guvnor, then I saved the file like drl on file system and I tried loading this drl file through application and all have worked fine. Our application is using this url: http://localhost:8080/guvnor/org.drools.guvnor.Guvnor/package/org.dfms.model/LATEST to loading from Guvnor5.3.0 the pkg. Is it correct?

org.tass.utils.ExpertSystemManager.java is our class and the source code is
this:
153. *public* *void* insertObservation(String entryPoint,
Observation obs) {
154. *try* {
155. *if*(entryPoints.containsKey(entryPoint)) {

Where is org.tass.utils coming from? it is our class.

I agree, at the line 48 there isn't code. It would seem that "Drools 5.3.0
final" has different binary and source code.

The package compilation is ok.

org.tass.utils.ExpertSystemManager.java is our class. We aren't using
third-party

Hello,
first of all, I would like to thank you for suggestions.
I tried loading drl from file and all work fine. The issue append when the
application load from Guvnor5.3.0 the pkg.
In particular the exception (I mentioned above) happens before calling the
method "SituationManager.createAccessControlEvent":
*public* *static* Event *createAccessControlEvent(*ACObservation obs,
String description, *int* threat_level, Geometry location, *int* sensorid) {
Event event = *new* AccessControlEvent(description,
threat_level, (Geometry)location.clone(), sensorid, obs.getLoginfo(),
obs.getErrno(), obs.getPersonelId());
event.addObservation(obs.getServiceIdentification());
*return* event;
}
I opened the source code at line 56 of
org.drools.reteoo.ReteooFactHandleFactory (I'm using Drools 5.3.0 final):
45. *protected* *final* InternalFactHandle newFactHandle(*final* *int* id,
46. *final* Object object,
47. *final* *long* recency,
48. *final*
ObjectTypeConf conf,
49. *final*
InternalWorkingMemory workingMemory,
50. *final*
WorkingMemoryEntryPoint wmEntryPoint) {
51.*if* ( conf != *null* && conf.isEvent() ) {
52.TypeDeclaration type = conf.getTypeDeclaration();
53.*long* timestamp;
56.*if* ( type.getTimestampExtractor() != *null* ) {
57.*if* ( Date.*class*.isAssignableFrom(
type.getTimestampExtractor().getExtractToClass() ) ) {
58.timestamp = ((Date)
type.getTimestampExtractor().getValue( workingMemory,
59.
object )).getTime();
60.} *else* {
it seems that "type" is null.

Carolina

[rules-users] The drools.packagebuilder.conf directory
Hi all I am novice on GUVNOR/DROOLS, but I defined some Drools Evaluator functions and to make the function available to the rules engine I inserted drools.packagebuilder.conf into user home directory. Is there different directory to do this? Thank you in advance, Carolina Pellecchia ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
