[rules-users] How to insert values into drl

[anjana.ackroyd]

Hi,
I am new to drools and trying to figure out how to get this simple example
working.
I have intellij IDE . 
I am trying to compare two numbers using drools 6.x and dont know how to
insert numberone and numbertwo after I get my drl file into my file system

Here is my code

RuleRunner.java
package com.cambiahealth.enterprise.service.droolsrule;

import org.kie.api.KieServices;
import org.kie.api.builder.KieBuilder;
import org.kie.api.builder.KieFileSystem;
import org.kie.api.builder.KieRepository;
import org.kie.api.builder.Message.Level;
import org.kie.api.io.KieResources;
import org.kie.api.io.Resource;
import org.kie.api.runtime.KieContainer;
import org.kie.api.runtime.KieSession;

public class RuleRunner
{
    private KieServices kieServices;
    private KieContainer kieContainer;
    private KieSession kieSession;
    private KieResources kieResources;
    private KieFileSystem kieFileSystem;
    private KieRepository kieRepository;

    public RuleRunner()
    {
        this.kieServices = KieServices.Factory.get();
        this.kieResources = kieServices.getResources();
        this.kieFileSystem = kieServices.newKieFileSystem();
        this.kieRepository = kieServices.getRepository();
    }


    public void addRuleFile(String packagename, String rulefile)
    {
        Resource resource = kieResources.newClassPathResource(rulefile);

        packagename = packagename.replace(".","/");

        String resourcepath =
"src/main/resources/"+packagename+"/"+rulefile;

        kieFileSystem.write(resourcepath, resource);
    }

    public KieSession buildKnowledgeSession()
    {
        KieBuilder kb = kieServices.newKieBuilder(kieFileSystem);

        kb.buildAll();

        if (kb.getResults().hasMessages(Level.ERROR))
        {
            throw new RuntimeException("Build Errors:\n" +
kb.getResults().toString());
        }

        kieContainer =
kieServices.newKieContainer(kieRepository.getDefaultReleaseId());

        kieSession = this.kieContainer.newKieSession();

        return kieSession;
    }

    public KieSession fireAllRules()
    {
        kieSession.fireAllRules();

        return kieSession;
    }

    public void dispose()
    {
        this.kieSession.dispose();
    }
}
							





My numbercompare.drl 


declare NumberCompare
    message: String
    numberone: Integer
    numbertwo: Integer
end

rule "numberone is equals to numbertwo"
    when
        n: NumberCompare(numberone == numbertwo);

    then
        n.setMessage("numberone is equals to numbertwo");
end

rule "numberone is greater than numbertwo"
    when
        n: NumberCompare(numberone > numbertwo);

    then
        n.setMessage("numberone is greater than numbertwo");
end

rule "numberone is less than numbertwo"
    when
        n: NumberCompare(numberone < numbertwo);

    then
        n.setMessage("numberone is less than numbertwo");
end









My DroolsService.java where I want to pass in values 1 and 2 to the drl file


        runner.addRuleFile("drools", "compareNumberRule.drl");

       KieSession kieSession = runner.buildKnowledgeSession();
      //How do I pass 1 as numberone and 2 as numbertwo values ????? before
firerules
        runner.fireAllRules();
        runner.dispose();
        return number.getMessage();  //To change body of implemented methods
use File | Settings | File Templates.
    }
}
