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=\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;

ksconf.setOption(ClockTypeOption.get("pseudo"));

// 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,

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 I’m 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>

</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 I’m 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!

Best regards
