测试工作类

 //测试工作类
 //TestJob.java

 package quartzPackage;

 import java.text.SimpleDateFormat;
 import java.util.Date;

 import org.quartz.Job;
 import org.quartz.JobExecutionContext;
 import org.quartz.JobExecutionException;

 public class TestJob implements Job {
     SimpleDateFormat DateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
     Date d = new Date();
     String returnstr = DateFormat.format(d);

第三方包

通过测试。一个简单任务只需要以下几个包：commons-beanutils.jar、commons-collections.jar、commons-logging.jar、commons-digester.jar、quartz.jar即可

名称	必须/备注	网址
activation.jar	主要是 JavaMail 要用到	http://java.sun.com/products/javabeans/glasgow/jaf.html
commons-beanutils.jar	是	http://jakarta.apache.org/commons/beanutils
commons-collections.jar	是	http://jakarta.apache.org/commons/collections
