Re: [rules-users] kContainer.newKieSession() fails in Apache Karaf

I'm trying to run Drools in an OSGi container (Apache Karaf 2.3.3 to be precise). When I try to call newKieSession() on a KieContainer, I get an exception as follows: java.lang.IllegalArgumentException: conflict Resolver 'org.drools.core.conflict.DepthConflictResolver' not found at org.drools.core.RuleBaseConfiguration.determineConflictResolver(RuleBaseConfiguration.java:868)[276:org.drools.core:6.0.1.20131220-0333] at org.drools.core.RuleBaseConfiguration.init(RuleBaseConfiguration.java:459)[276:org.drools.core:6.0.1.20131220-0333] at org.drools.core.RuleBaseConfiguration.init(RuleBaseConfiguration.java:415)[276:org.drools.core:6.0.1.20131220-0333] at org.drools.core.RuleBaseConfiguration. <init> (RuleBaseConfiguration.java:402)[276:org.drools.core:6.0.1.20131220-0333] at org.drools.core.impl.KnowledgeBaseFactoryServiceImpl.newKnowledgeBaseConfiguration(KnowledgeBaseFactoryServiceImpl.java:37)[276:org.drools.core:6.0.1.20131220-0333] at org.kie.internal.KnowledgeBaseFactory.newKnowledgeBaseConfiguration(KnowledgeBaseFactory.java:125)[275:org.kie.internalapi:6.0.1.20131220-0322] at org.drools.compiler.kie.builder.impl.KieContainerImpl.getKnowledgeBaseConfiguration(KieContainerImpl.java:323)[277:org.drools.compiler:6.0.1.20131220-0333] at org.drools.compiler.kie.builder.impl.KieContainerImpl.createKieBase(KieContainerImpl.java:316)[277:org.drools.compiler:6.0.1.20131220-0333] at org.drools.compiler.kie.builder.impl.KieContainerImpl.getKieBase(KieContainerImpl.java:257)[277:org.drools.compiler:6.0.1.20131220-0333] at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:400)[277:org.drools.compiler:6.0.1.20131220-0333] at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:349)[277:org.drools.compiler:6.0.1.20131220-0333] at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:331)[277:org.drools.compiler:6.0.1.20131220-0333] As a workaround, I was able to get it working by doing this: KieBaseConfiguration kbaseConf = KnowledgeBaseFactory .newKnowledgeBaseConfiguration( null, getClass().getClassLoader(), RuleBaseConfiguration.class.getClassLoader() ); KieBase kbase = kContainer.newKieBase(kbaseConf); kSession = kbase.newKieSession(); but this is obviously less than ideal. Any ideas on how to make this work better in OSGi? Thank you! Joseph
