[rules-users] ProviderInitializationException in creating KnowledgeBuilder

Hi all, I'm using CR1 version of drools and when I tried to create KnowledgeBuilder: if (rulePackage.exists()) { final KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(ResourceFactory.newFileResource(rulePackage), ResourceType.PKG); ..... I got the ProviderInitializationException as follows: 09:38:18,125 ERROR [test.drools.common.ejb.ExceptionInterceptor] [] Provider org.drools.builder.impl.KnowledgeBuilderProviderImpl could not be set. org.drools.ProviderInitializationException: Provider org.drools.builder.impl.KnowledgeBuilderProviderImpl could not be set. at org.drools.builder.KnowledgeBuilderFactory.loadProvider(KnowledgeBuilderFactory.java:111) at org.drools.builder.KnowledgeBuilderFactory.getKnowledgeBuilderProvider(KnowledgeBuilderFactory.java:101) at org.drools.builder.KnowledgeBuilderFactory.newKnowledgeBuilder(KnowledgeBuilderFactory.java:29) I use drools-core and drools-api in the project and I found out that the class Provider org.drools.builder.impl.KnowledgeBuilderProviderImpl doesn't even exist. Do I miss any package? And a second question, when will the javadoc of drools be online again? ;-) Thanks Brody -- View this message in context: http://www.nabble.com/ProviderInitializationException-in-creating-Knowled...
