Re: [rules-users] java.lang.RuntimeException: Unable to instance KieServices

Hi I am trying to get started with Drools 6x, and in eclipse, I have created a Drools project, which creates the boilerplate code to run a simple drl. I have the drools runtime installed via Eclipse. Yet, when I try to run the following, I get the following error: java.lang.ExceptionInInitializerError at com.sample.DroolsTest.main(DroolsTest.java:15) Caused by: java.lang.RuntimeException: Unable to instance KieServices at org.kie.api.KieServices$Factory.<clinit>(KieServices.java:167) ... 1 more Caused by: java.lang.ClassNotFoundException: org.drools.compiler.kie.builder.impl.KieServicesImpl at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at org.kie.api.KieServices$Factory.<clinit>(KieServices.java:165) ... 1 more package com.sample; import org.kie.api.KieServices; import org.kie.api.runtime.KieContainer; import org.kie.api.runtime.KieSession; /** * This is a sample class to launch a rule. */ public class DroolsTest { public static final void main(String[] args) { try { // load up the knowledge base KieServices ks = KieServices.Factory.get(); KieContainer kContainer = ks.getKieClasspathContainer(); KieSession kSession = kContainer.newKieSession("ksession-rules"); // go !
