Feki Ahmed [https://community.jboss.org/people/bardelman] created the discussion "How to resume a process instance from a loaded session in jbpm 5.0" To view the discussion, visit: https://community.jboss.org/message/797952#797952 -------------------------------------------------------------- Hi, i ve tried to load a session from the database with the loadStatefulKnowledgeSession, and then i tried to active a process Instance from that loaded session so i tried with  ksession.startProcess(String processId) but it started a new process instance and not the old persisted one. now i know that startProcess isn't the appropriate method to do that but i still don't know what's the right way ... here is my code , it s a java class: public static void main(String[] args) {                     ksession = ReloadSession(SessionId, taskname);                     UserTransaction ut = null;                     try {                               ut = (UserTransaction) new InitialContext().lookup( "java:comp/UserTransaction" );                     } catch (NamingException e1) {                               e1.printStackTrace();                     }                     try {                               ut.begin();                     } catch (NotSupportedException e) {                               e.printStackTrace();                     } catch (SystemException e) {                               e.printStackTrace();                     }                     processInstance = ksession.startProcess(taskname);                     ksession.fireAllRules();                     try {                               ut.commit();                     } catch (IllegalStateException e) {                               e.printStackTrace();                     } catch (SecurityException e) {                               e.printStackTrace();                     } catch (HeuristicMixedException e) {                               e.printStackTrace();                     } catch (HeuristicRollbackException e) {                               e.printStackTrace();                     } catch (RollbackException e) {                               e.printStackTrace();                     } catch (SystemException e) {                               e.printStackTrace();                     }           } private StatefulKnowledgeSession ReloadSession(String tasktoreloadidSession,String tasktoreloadname){                     StatefulKnowledgeSession ksession =null;                     try {                   UserTransaction ut = (UserTransaction) new InitialContext().lookup( "java:comp/UserTransaction" );             ut.begin();             ksession = JbpmAPIUtil.loadStatefulKnowledgeSession(Integer.parseInt(tasktoreloadidSession), tasktoreloadname+".bpmn");                   /*Create the knowledge base  */                               KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newThreadedFileLogger(ksession, "testlog", 1000);                               CommandBasedWSHumanTaskHandler taskHandler = new CommandBasedWSHumanTaskHandler(ksession);                               ksession.getWorkItemManager().registerWorkItemHandler("Human Task", taskHandler);                               taskHandler.connect();                               ut.commit();                               logger.close();                     } catch (Throwable t) {                               log.error(t.getMessage(), t.getCause());                               throw new RuntimeException("error while reloading session",t);                     }                     return ksession;           } public static StatefulKnowledgeSession loadStatefulKnowledgeSession(int idsession,String processName) throws Exception {                     /*                      * Create the knowledgebase using the required bpmn and drl files                      */                     KnowledgeBase kbase = readKnowledgeBase(processName);                     EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );                     Environment env = KnowledgeBaseFactory.newEnvironment();                     env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );                     env.set( EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager() );                     env.set( EnvironmentName.GLOBALS, new MapGlobalResolver() );                     Properties properties = new Properties();                     properties.put("drools.processInstanceManagerFactory", "org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory");                     properties.put("drools.processSignalManagerFactory", "org.jbpm.persistence.processinstance.JPASignalManagerFactory");                     KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);                     return JPAKnowledgeService.loadStatefulKnowledgeSession(idsession,kbase, config, env);           } unfortunatelly, the user guide do not talk about this enough. i need your help please !! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/797952#797952] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
