my current code

  JournalArticle journalArticle = JournalArticleLocalServiceUtil.getArticle(id);
            getPermissionChecker().init(u.getUser(), true);

            WorkflowInstanceLink wil= WorkflowInstanceLinkLocalServiceUtil.getWorkflowInstanceLink(companyId, journalArticle.getGroupId(), JournalArticle.class.getName(), journalArticle.getId());
            WorkflowInstance workflowInstance = WorkflowInstanceManagerUtil.getWorkflowInstance(companyId, wil.getWorkflowInstanceId());
            Map<String, Serializable> workflowContext = workflowInstance.getWorkflowContext();

            List<Integer> logTypes_assign = new ArrayList<Integer>();
            logTypes_assign.add(WorkflowLog.TASK_ASSIGN);
            List<WorkflowLog> workflowLogs_assign = WorkflowLogManagerUtil.getWorkflowLogsByWorkflowInstance(companyId, wil.getWorkflowInstanceId(), logTypes_assign, QueryUtil.ALL_POS, QueryUtil.ALL_POS, WorkflowComparatorFactoryUtil.getLogCreateDateComparator(true));
            //WorkflowPermissionUtil.hasPermission(permissionChecker, groupId, className, classPK, actionId);

            if(workflowLogs_assign.size() > 0){             
                long taskId = workflowLogs_assign.get(workflowLogs_assign.size()-1).getWorkflowTaskId();
                WorkflowTask task = WorkflowTaskManagerUtil.getWorkflowTask(companyId, taskId);
                _log.info("task : "+task.getName());
                WorkflowTask nextTask = WorkflowTaskManagerUtil.assignWorkflowTaskToUser(companyId, userId, task.getWorkflowTaskId(), userId, "auto assign", task.getDueDate(), workflowContext);               
                WorkflowTaskManagerUtil.completeWorkflowTask(companyId, userId, nextTask.getWorkflowTaskId(), "next task transition name", "next task name", workflowContext);
            }

workflowInstance1 = WorkflowInstanceManagerUtil.signalWorkflowInstance(service.getCompanyId(), user.getUserId(),
            workflowInstanceId, transitionNAME, workflowInstance.getWorkflowContext());
