Hello,

I had already tried  something like that by changing  the packages field in the kmodule file into packages=”rules” as this is the directory where the VAP.drl file resides. But I still get a null pointer exception when executing the container verify, although I do not see a warning anymore:

 

 

The error comes from the line 36 (container verify):

 

System.out.println(kContainer.verify().getMessages().toString());

 

 

I am running out of ideas, I also thought that it maybe has something to do with maven as I have read that drools 601 expects a maven structure, so I definitely needs a pom.properties. I have a pom.properties but is has no content, only this:

 

version=${project.version}

groupId=${project.groupId}

artifactId=${project.artifactId}

 

Thanks!

Try creating a directory called: InfectionRules inside the src/main/resources/

and then put the rules inside there.

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…”)

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;

              KieContainer kContainer = ks.getKieClasspathContainer();

              System.out.println(kContainer.verify().getMessages().toString());

             KieSession kSession = kContainer.newKieSession("VAPSession");

             KieSessionConfiguration ksconf = KieServices.Factory.get().newKieSessionConfiguration();

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

            

             SessionPseudoClock clock = kSession.getSessionClock();

             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 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 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 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

Natalia
