I've used the Variables to build Business Keys. This is how I've managed to solve the problem: //......Start process...... Map<String, Object> variables = new HashMap<String, Object>();   variables.put("business_key", buildBusinessKeyForMyObject(myObject));   kSession.startProcess("my_workflow_id",variables); //......................................       //.........Get Process Instances Id of My Object....... Query query = entityManager.createQuery("FROM " + VariableInstanceLog.class.getName() + " variable " +       " WHERE variable.variableId = :business_key_id          AND variable.value = :business_key_value);        query.setParameter("business_key_id", "business_key");      query.setParameter("business_key_value", buildCoreDataBusinessKey(coreData));        List<VariableInstanceLog> resultList = query.getResultList();   for (VariableInstanceLog variableInstanceLog : resultList) {      logger.info("******* " + variableInstanceLog.getProcessInstanceId()); } //...............................................................   -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/742644#742644] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
