package test ;
import java.util.Date;
import org.quartz.Job;
import org.quartz.JobDetail;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.SimpleTrigger;
import org.quartz.Trigger;
import org.quartz.impl.StdSchedulerFactory;
/** * @author snowway * @version $Id$ */
public class SayHelloWorldJob implements Job{

public void execute(JobExecutionContext context) throws JobExecutionException{
System.out.println("hello world!");
}

public static void main(String[] args) throws Exception{

SchedulerFactory factory = new StdSchedulerFactory();

Scheduler scheduler = factory.getScheduler();

JobDetail jobDetail = new JobDetail("SayHelloWorldJob",
Scheduler.DEFAULT_GROUP,
SayHelloWorldJob.class);

Trigger trigger = new SimpleTrigger("SayHelloWorldJobTrigger",Scheduler.DEFAULT_GROUP,
new Date(), null, 5, 5000L);
System.out.println("55555555555555");
scheduler.scheduleJob(jobDetail, trigger);
System.out.println("666666666666666666");
scheduler.start();

}

}

我想实现一个定时功能，例如周一至周六的每天11点做一件事情，
但是 JobDetail jobDetail = new JobDetail("SayHelloWorldJob",
Scheduler.DEFAULT_GROUP,
SayHelloWorldJob.class);
这个代码出来以下异常 Exception in thread "main" java.lang.NoSuchMethodError: org.apache.commons.collections.SetUtils.orderedSet(Ljava/util/Set;)Ljava/util/Set;
at org.quartz.JobDetail.<init>(JobDetail.java:85)
at test.SayHelloWorldJob.main(SayHelloWorldJob.java:25)

请达人指点下，在线等
