Try creating a directory called: InfectionRules inside the src/main/resources/and then put the rules inside there.On Sun, May 25, 2014 at 3:04 PM, Natalia Iglesias de Amunategui <natalia.iglesias@casadearriba.net> wrote:
_______________________________________________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

java.lang.NullPointerException

The kie initialization module has the following code:
package InfectionRules;

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 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
