I added that but it was asking to define getkbase().So I manupulated the code.Kindly have a look and advice me that how can I correct it.
Also tell me how can I test this concept.Where to find out the database in which the details are stored.

For your reference the code is as below:


package sample;
import org.drools.KnowledgeBase;
import org.drools.KnowledgeBaseFactory;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.ResourceFactory;
import org.drools.persistence.jpa.JPAKnowledgeService;
import org.drools.runtime.StatefulKnowledgeSession;
import org.jbpm.process.audit.JPAWorkingMemoryDbLogger;
import org.jbpm.test.JBPMHelper;

public class historyLog  {
 /**
  * @param args
  */
 public static void main(String[] args)  throws Exception {
  // TODO Auto-generated method stub
  //JBPMHelper.startH2Server();
  //JBPMHelper.setupDataSource();
  
  //EntityManagerFactory emf =
  //    Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );

  org.drools.runtime.Environment env = KnowledgeBaseFactory.newEnvironment();
  KnowledgeBase kbase = readKnowledgeBase();
  
  //StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); 
  //JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(ksession);

  StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
  JPAWorkingMemoryDbLogger jbpmLogger = new JPAWorkingMemoryDbLogger(ksession);
  ksession.startProcess("sample.bpmn.hh");  
  jbpmLogger.dispose();
 
 }

 private static KnowledgeBase readKnowledgeBase() throws Exception {
  KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
  kbuilder.add(ResourceFactory.newClassPathResource("demo2.bpmn"), ResourceType.BPMN2);
  return kbuilder.newKnowledgeBase();
 }
 
}
