Hi folks
I am new in this field, I tried to test and learn sample project (Hello World) and it is showing error in importing org.drools.KnowledgeBaseFactory.
How I can import org.drools.KnowledgeBaseFactory or other
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderError;

import org.drools.logger.KnowledgeRuntimeLogger;
import org.drools.logger.KnowledgeRuntimeLoggerFactory;
