How It Works

Using Quartz Without Spring's Support
To use Quartz for scheduling, first create your job by implementing the Job interface. For example, the
following job executes the replicate() method of a file replicator, retrieved from the job data map
through the JobExecutionContext object that's passed in.

■ Note To use Quartz in your application, you must include quartz-all-1.6.0.jar (located in the lib/quartz

directory of the Spring installation), commons-collections.jar (located in lib/jakarta-commons ), and jta.jar
(located in lib/j2ee ) in your classpath.

package com.apress.springenterpriserecipes.replicator;
...
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class FileReplicationJob implements Job {

public void execute(JobExecutionContext context)
throws JobExecutionException {
Map dataMap = context.getJobDetail().getJobDataMap();
FileReplicator fileReplicator =
(FileReplicator) dataMap.get("fileReplicator");
try {
fileReplicator.replicate();
} catch (IOException e) {
throw new JobExecutionException(e);
}
}
}

After creating the job, you configure and schedule it with the Quartz API. For instance, the following
scheduler runs your file replication job every 60 seconds with a 5-second delay for the first time of
execution:

package com.apress.springenterpriserecipes.replicator;
...
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SimpleTrigger;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
