Drools 601 kmodule problem when running the drools project in eclipse kepler ide

by Natalia Iglesias de Amunategui

Hello, I am currently working on a Drools project using eclipse kepler and the drools plug-in from drools 601. I have a main java class that contains POJO classes representing facts and the initialization of the kie container and session. When executing the command System.out.println(kContainer.verify().getMessages().toString()); I get the following messages:(note the warning No files found for KieBase InfectionRules, searching folder) [main] INFO org.drools.compiler.kie.builder.impl.ClasspathKieProject - Found kmodule: file:/C:/TFM/Infections/Workspace/InfectionRules/VAP/target/META-INF/kmodule ..xml [main] INFO org.drools.compiler.kie.builder.impl.KieRepositoryImpl - KieModule was added:FileKieModule[ ReleaseId=${project.groupId}:${project.artifactId}:${project.version}file=\T FM\Infections\Workspace\InfectionRules\VAP\target] [main] INFO org.drools.compiler.kie.builder.impl.ClasspathKieProject - Found kmodule: file:/C:/TFM/Infections/Workspace/InfectionRules/VAP/target/META-INF/kmodule ..xml [main] INFO org.drools.compiler.kie.builder.impl.KieRepositoryImpl - KieModule was added:FileKieModule[ ReleaseId=${project.groupId}:${project.artifactId}:${project.version}file=\T FM\Infections\Workspace\InfectionRules\VAP\target] [main] WARN org.drools.compiler.kie.builder.impl.AbstractKieModule - No files found for KieBase InfectionRules, searching folder \TFM\Infections\Workspace\InfectionRules\VAP\target [] java.lang.NullPointerException at InfectionRules.VAPDroolsTest.main(VAPDroolsTest.java:62) The kie initialization module has the following code: package InfectionRules; import java.util.*; import java.util.concurrent.TimeUnit; import java.text.DateFormat; import java.text.SimpleDateFormat; import org.drools.core.time.*; import org.kie.internal.*; import org.kie.api.conf.EventProcessingOption; import org.kie.api.runtime.KieRuntime; import org.kie.api.KieBaseConfiguration; import org.kie.api.KieServices; import org.kie.api.runtime.KieContainer; import org.kie.api.runtime.KieSession; import org.kie.api.runtime.KieSessionConfiguration; import org.kie.api.runtime.conf.ClockTypeOption; import org.kie.api.runtime.rule.EntryPoint; import org.kie.api.runtime.rule.FactHandle; import org.kie.api.time.SessionClock; public static void main(final String[] args) { try { // load up the knowledge base KieServices ks = KieServices.Factory.get(); KieContainer kContainer = ks.getKieClasspathContainer(); System.out.println(kContainer.verify().getMessages().toString()); KieSession kSession = kContainer.newKieSession("VAPSession"); // set clock to pseudo clock to be able to advance it manually KieSessionConfiguration ksconf = KieServices.Factory.get().newKieSessionConfiguration(); ksconf.setOption(ClockTypeOption.get("pseudo")); SessionPseudoClock clock = kSession.getSessionClock(); // set stream mode as opposite to cloud mode KieBaseConfiguration config = KieServices.Factory.get().newKieBaseConfiguration(); config.setOption(EventProcessingOption.STREAM ); // Insert test patients and related classes // mr Jones has no VAP, so the cpi score is less than 6 final Patient p1 = new Patient( "MrJones", 45, 1, false,false,true,37.0, 5000,"None","No Infiltrate","None","No Growth","S.Aureus",235,true, false, 0, true,new SimpleDateFormat("yyyy-MM-dd").parse("2014-05-17"),"", new SimpleDateFormat("yyyy-MM-dd").parse("2014-05-17"),false,false,false,false); kSession.insert( p1 ); // get a reference to the entry point and insert events EntryPoint nursingStream = kSession.getEntryPoint( "NursingStream" ); final CPIScore cpiScore1 = new CPIScore( p1,"initial",7); nursingStream.insert( cpiScore1 ); clock.advanceTime( 75, TimeUnit.HOURS ); final CPIScore cpiScore2 = new CPIScore( p1,"3days",7 ); nursingStream.insert( cpiScore2 ); I am running this class directly from the Eclipse Run menu option. I have installed maven but Im not using it (yet) The kmodule.xml file has the following format: <?xml version="1.0" encoding="UTF-8"?> <kmodule xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://jboss.org/kie/6.0.0/kmodule"> <kbase name="InfectionRules" eventProcessingMode="stream" packages="InfectionRules"> <ksession name="VAPSession" type="stateful" clockType="pseudo" /> </kbase> </kmodule> (I have tried to change the packages field of kmodule to *, but it does not work either.) And the directory structure where both the java and drl code reside is: C:\TFM\Infections\Workspace\InfectionRules\VAP\src\main Subdirectory java contains the java classes and resources the drl file. The target directory is located under ..\VAP\target\ with the following structure: >From Eclipse IDE this is the project structure Any idea as to what Im doing wrong? I don´t know why the kmodule does not locate the kbase in the directory \TFM\Infections\Workspace\InfectionRules\VAP\target as this directory contains the drl file vap.drl in the rules subdirectory. Although I get later a null pointer exception, I guess that it has to do with this warning, as if there is no kbase located no session can be used. Thanks in advance!

Suspicious behaviour when using a bound variable as a constraint in a pattern bound to the same var

by dec

Due to a bug we came up with the following rule: /* Rule "intriguing" when $foo: Foo( $foo.getBar() == null ) then ... */ Our original intention was to actually generate the rule like so: /* Rule "intended" when $foo: Foo( bar == null ) then ... */ In most cases the "intriguing" rule actually seem to behave much like the "intended". We are unsure way. Moreover, we suspect that sometime we get wrong, or rather unexpected results when firing up this rule. -- View this message in context: http://drools.46999.n3.nabble.com/Suspicious-behaviour-when-using-a-bound...

OptaPlanner VRPTW Benchmark?

by Paul Strohn

Might anyone on the list have come across Gehring & Homberger VRPTW benchmark <http://www.sintef.no/Projectweb/TOP/VRPTW/Homberger-benchmark/1000-custom...> figures for Planner? Given that record performance in the benchmark is something to brag about <https://www.youtube.com/watch?v=apiuF6Z8O1k> in some circles when pitching an optimizer to business customers, it would be great to see how OptaPlanner stacks up! -- View this message in context: http://drools.46999.n3.nabble.com/OptaPlanner-VRPTW-Benchmark-tp4029663.html Sent from the Drools: User forum mailing list archive at Nabble.com.

XML and the Guided Decision Tables

by Kysis

Hello my team and I are trying to write a script in order to convert and condense a decision table to import it into the workbench as a Guided Decision Table. Is there documentation for the XML file that represents a GDT? Thanks, Michael. -- View this message in context: http://drools.46999.n3.nabble.com/XML-and-the-Guided-Decision-Tables-tp40...

Is @PropertySpecific supported in Drools 5.6.0

by RavishankarHassain

I was looking fro some examples and document which explains on how to use the @Modifies annotations inside Facts(Java class) and it happened for me to see this doc http://docs.jboss.org/drools/release/5.4.0.Beta2/droolsjbpm-introduction-... I tired to implement @PropertySpecific and @Modifies according to the session 3.1.2.1. Fine Grained Property Change Listeners (Property Specific) which is briefly described in the above mentioned link But, when I tried to use @PropertySpecific annotation in my Facts(java class) Eclipse IDE is not able to identify or resolve the package for @PropertySpecific annotation. I am using Drools 5.6.0. Is this @PropertySpecific annotation still supported in Drools, if yes then where is it ? in which package and in which jar ? -- View this message in context: http://drools.46999.n3.nabble.com/Is-PropertySpecific-supported-in-Drools...

KieScanner The KieScanner is a maven-oriented replacement of the KnowledgeAgent present in Drools 5. using knowledgwAgent I have linked through changeset.xml by below code in drools 5.4 KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("MyAgent1",kbase, kconf); ResourceFactory.getResourceChangeNotifierService().start(); ResourceFactory.getResourceChangeScannerService().start(); kagent.applyChangeSet(ResourceFactory.newUrlResource("http://localhost:8380/drools-guvnor/ChangeSet.xml")); kbase = kagent.getKnowledgeBase(); How I can achieve this using drools 6 to interact with my java code to drools workbench. or which drools 6 need to download to interact with java code.

Rules compilation error with OSGi integration (6.1.0.Beta3)

by Ephemeris Lappis

Hello. We have a very simple rules file that works as expected when running as a JUnit test in Eclipse with Maven dependencies, but fails when it is executing in ServiceMix with OSGi integration. The code is just like : raw> Map<String, Object> dialog = new LinkedHashMap<>(); KieSession kieSession = kieContainer.newKieSession("MyKSession"); kieSession.setGlobal("dialog", dialog); kieSession.insert(problem); kieSession.fireAllRules(); kieSession.dispose(); The rules file : And the kmodule.xml : The compilation error is about Java 7 syntax elements (as generics or thousand separators in number literals for example), and seems to indicate that in this case the compiler is not the same, and it expects another Java syntax. No error is reported when the KieContainer is created from the KModule.xml, but the following error occurs when using it for KSession creation. This occurs both with the prepackaged feature (http://repo1.maven.org/maven2/org/drools/drools-karaf-features/6.1.0.Beta...), or with an adapted one. For example, the Maven dependancies classpath in eclipse mentions newer versions of the Eclipse's ECJ. But changing the version of bundles has no effect... What is missing in the feature to activate the correct rules compiler ? Thanks for your help ?
