Re: [rules-users] can't get samples to work from Drools 5 drools-doc-expert

Darrin, You have it except for 1 important line of code kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); Need to add the built packages to the rule base :) 2009/4/24 Darrin Mison <dmison(a)redhat.com&gt; Hi, I'm very new to Drools and I'm trying to get code running based on the first sample code from the QuickStart chapter of the drools- doc-expert. It compiles and runs (tried on commandline & in JBoss Dev Studio 2.0.0.GA) but does not work, ie it always says "rejected" instead of "accepted". I've had to fill out a bit of code to get it to compile so I may be doing something completely wrong. I've included the code (rule, model, main) below. Any help would be really appreciated. Darrin #Sample.drl package com.company.license rule "Is of valid age" when $a : Applicant( age > 18); then $a.setValid( true ); System.out.println("true"); end //Applicant.java package com.company.license; public class Applicant { private String name; private int Age; private boolean valid; // getter and setter methods here public String getName() { return name; } public int getAge() { return Age; } public boolean getValid(){ return valid; } public void setName(String s){ this.name = s; } public void setAge(int i){ this.Age = i; } public void setValid(boolean v){ this.valid = v; } } //ruletest.java package com.company.license; import org.drools.builder.*; import org.drools.io.*; import org.drools.runtime.*; import org.drools.*; public class ruletest { public ruletest(){} public static void main(String args[]) { ruletest rt = new ruletest(); rt.go(); } public void go() { Applicant dude = new Applicant(); dude.setName("Rufus"); dude.setAge(32); System.out.println(dude.getName()); System.out.println("test: "+dude.getValid()); KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); Resource ruleResource = ResourceFactory.newClassPathResource( "Sample.drl", getClass() ); kbuilder.add( ruleResource, ResourceType.DRL ); if ( kbuilder.hasErrors() ) System.err.println( kbuilder.getErrors().toString() ); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession(); System.out.println( dude.getValid() ); //should display false ksession.execute( dude ); if (dude.getValid()) System.out.println("Application approved"); //should display due to hardcoded as of 32 else System.out.println("Application rejected"); } } _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
