java.lang.VerifyError org/drools/reteoo/ReteooRuleBase, method: setupRete signature: ()V

by ivonne

Hi I am using jboss 4.2 and drools core 5.4.0.Final. The application was working fine but without any change it started to throw an error when spring bean for kbase is created. This is the error: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kbase': Invocation of init method failed; nested exception is java.lang.VerifyError: (class: org/drools/reteoo/ReteooRuleBase, method: setupRete signature: ()V) Incompatible argument to function If I run the application using jetty it works fine. I've been looking about the error with any sucess. Thanks -- View this message in context: http://drools.46999.n3.nabble.com/java-lang-VerifyError-org-drools-reteoo...

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.

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.

London (May 26th) Drools & jBPM community contributor meeting

by Mark Proctor

London, Chiswick, May 26th to May 30th During next week a large percentage of the Drools team, some of the jBPM team and some community members will be meeting in London (Chiswick). There won’t be any presentations, we’ll just be in a room hacking, designing, exchanging ideas and planing. This is open to community members who wish to contribute towards Drools or jBPM, and want help with those contributions. This also includes people working on open source or academic projects that utilise Drools or jBPM. Email me if you want to attend, our locations may very (but within chiswick) each day. We will not be able to make the day time available to people looking for general Drools or jBPM guidance (unless you want to buy us all lunch). But we will be organising evenings things (like bowling) and could make wed or thu evening open to people wanting general chats and advice. Email me if you’re interested, and after discussing with the team, I’ll let you know. Those currently attending: Mark Proctor (mon-fri) Group architect Edson Tirelli (mon-fri) Drools backend, and project lead Mario Fusco (mon-fri) Drools backend Davide Sottara (wed-fri) Drools backend Alex Porcelli (mon-fri) Drools UI Michael Anstis (thu-fri) Drools UI Kris Verlaenen (wed-thu) jBPM backend, and project lead Mauricio Salatino (mon-fri) jBPM tasks and general UI
