rule help

[SzA84]

Hi I am working on a simple drools project.
I have now one rule, but it not works.

This is the drl:

package orvosi;
import orvosi.orvosimeres.Adattipus;
import orvosi.orvosimeres.Mertadat;

rule "Your First Rule"
       
        when
                Adattipus(ertek="heart_rate");
                Mertadat(ertek>180, mertekegyseg=="/min",
                mozgas==true);
        then
                System.out.println ("riasztas");
               
end

And this is the orvosi.java in the package but I think it's not good so.
Suggest me any ideas how I can make it work.
Thx!

package orvosi;

import java.io.InputStreamReader;
import java.io.Reader;

import org.drools.RuleBase;
import org.drools.RuleBaseFactory;
import org.drools.WorkingMemory;
import org.drools.compiler.PackageBuilder;
import org.drools.rule.Package;


public class orvosimeres {
       
       
        public static final void main(String[] args) {
        try {
 RuleBase ruleBase = readRule();
            WorkingMemory workingMemory = ruleBase.newStatefulSession();
            Adattipus ertek = new Adattipus();
            Mertadat mertekegyseg = new Mertadat ();
            Mertadat mozgas = new Mertadat ();
            workingMemory.insert( ertek );
            workingMemory.insert( mertekegyseg );
            workingMemory.insert( mozgas );
            workingMemory.fireAllRules();  
} catch (Throwable t) {
            t.printStackTrace();
        }
    }
       
        private static RuleBase readRule() throws Exception {
                Reader source = new InputStreamReader( orvosimeres.class.getResourceAsStream( "/vernyomas.drl" ) );
               
       
                PackageBuilder builder = new PackageBuilder();

                builder.addPackageFromDrl( source );
               
                Package pkg = builder.getPackage();
               
                RuleBase ruleBase = RuleBaseFactory.newRuleBase();
                ruleBase.addPackage( pkg );
                return ruleBase;
        }
       
        public static class Adattipus{
                public int ertek;
        }
        public static class Mertadat{
                public int mertekegyseg;
                boolean mozgas=false;
                }
       

}

Hi,

As first look you must add the getters and setters methods into the model classes "Adattipus" and "Mertadat". In your rule you have written "Mertadat(ertek>180, mertekegyseg=="/min",mozgas==true);" but you dont have declared the field "ertek" in the class "Mertadat". And have also care with the field types, if you declare               
               public int mertekegyseg;
               boolean mozgas=false;
you can't write a precedence like
               Mertadat(ertek>180, mertekegyseg=="/min",  mozgas==true);

Hope to help,

Nestor

In addition to what Nestor has said, you'll also have to make sure your inserted facts objects contain values. You are just calling the default constructors
           Adattipus ertek = new Adattipus();
           Mertadat mertekegyseg = new Mertadat ();
           Mertadat mozgas = new Mertadat ();
           workingMemory.insert( ertek );
           workingMemory.insert( mertekegyseg );
           workingMemory.insert( mozgas );
for Adattipus and Mertadat.

Also, it seems that you are confusing your Mertadat fields "mertekegyseg" and "mozgas" with objects of the same name.

Minden jót!

Thx!

I downloaded the Guvnor 5.1.0M1 version, but then I found out I found out I can't add more than one condition to it now. there used to be a little bracket between two conditions but now it's gone. Is it a bug or it's a feature? How am I supposed to say startDate > 11/11/2009 and start date < 11/30/2009 now?

thanks
