重新启动weblogic后，预定的作业不会触发

Question

重新启动weblogic服务器后，已安排的作业不会触发预定作业。下面是代码。             我正在使用CronTrigger             我正在使用jobdetail

    CronTrigger trigger = new CronTrigger();
    trigger.setName(userId+"_"+packetId+"_"+jobFolderName);
    trigger.setGroup(userId);
    trigger.setCronExpression(cronexpression);
    trigger.setStartTime(starttimedate);
    trigger.setEndTime(endtimedate);

trigger.setMisfireInstruction(CronTrigger.MISFIRE_INSTRUCTION_SMART_POLICY);
                          

    job.setName(userId+"_"+packetId+"_"+jobFolderName);
    job.setGroup(userId);
    job.setVolatility(true);
    //job.setRequestsRecovery(true);
    job.setDurability(true);

Scheduler scheduler = new StdSchedulerFactory().getScheduler();
                                 
    scheduler.start();
    scheduler.scheduleJob(job, trigger);
    trigger.setStartTime(starttimedate);
    trigger.setEndTime(endtimedate);
                                      
trigger.setMisfireInstruction(CronTrigger.MISFIRE_INSTRUCTION_SMART_POLICY);
                                        
    job.setName(userId+"_"+packetId+"_"+jobFolderName);            
    job.setGroup(userId);
    job.setVolatility(true);
    job.setRequestsRecovery(true);
    job.setDurability(true);

    Scheduler scheduler = new StdSchedulerFactory().getScheduler();
    Scheduler.start();
    Scheduler.scheduleJob(job, trigger);

我使用的是石英1.6.3版本。
