Ashish Kumar [https://community.jboss.org/people/ashish_kumar] created the discussion "Re: Regarding Log file" To view the discussion, visit: https://community.jboss.org/message/743043#743043 -------------------------------------------------------------- I dont know the exact way to execute it but I was following the steps given in towards the end of chapter 7 of jBPM docs given in the jboss site. For your reference I am giving the code below.Kindly look into it and give some suggestions. Also tell me wheather I can find any autogenerated log file as we find in other tools like savvion to monitor the process. 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");               // do stuff (start processes, etc...)      jbpmLogger.dispose();   //logger.dispose(); } private static KnowledgeBase readKnowledgeBase() throws Exception {   KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();   kbuilder.add(ResourceFactory.newClassPathResource("demo2.bpmn"), ResourceType.BPMN2);   return kbuilder.newKnowledgeBase(); } }  -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/743043#743043] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
