public class CronQuartzJob implements Job {

	public CronQuartzJob() {
		
	}

	public void execute(JobExecutionContext context) throws JobExecutionException {
		System.out.println("In SimpleQuartzJob - executing its JOB at " + DateFormatUtils.format(new Date(), "yyyy-MM-dd") + " by " + context.getTrigger().getName());

	}

}

# org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingJobHistoryPlugin
org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingTriggerHistoryPlugin
# org.quartz.plugin.triggHistory.triggerFiredMessage = Trigger{1}.{0} fired job {6}.{5} at: {4, date, HH:mm:ss MM/dd/yyyy}
# org.quartz.plugin.triggHistory.triggerCompleteMessage = Trigger{1}.{0} completed firing job {6}.{5} at: {4, date, HH:mm:ss MM/dd/yyyy} with resulting trigger instruction code: {9}
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.fileName = quartz_job.xml

org.quartz.plugin.jobInitializer.overWriteExistingJobs = false
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHookPlugin
org.quartz.plugin.shutdownhook.cleanShutdown =true

quartz_job.xml代码如下：

<?xml version="1.0" encoding="UTF-8"?>

         </cron>  
      </trigger>
      
 </job>
</quartz>

【注】：工程中需要的jar如下：

commons-configuration-1.6.jar

commons-dbcp-1.4.jar

commons-digester3-3.0.jar

commons-logging-1.1.1.jar

commons-modeler-2.0.jar

commons-pool-1.5.6.jar

commons-validator-1.3.1.jar

jms.jar

jms.jar

jta.jar

log4j-1.2.16.jar


附件里实例代码。

----------------------------------------------------------------------
【说明】：上述工程的jar包组在Tomcat6和Jboss4下没问题，但在WebLogic10.3下就会报:
ERROR [[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)']: (Digester.java:794) - Digester.getParser:
java.lang.UnsupportedOperationException: This parser does not support specification " null" version " null"
含义：解析XML的文件版本不匹配。
【解决办法】：把上述工程的jar组中的 commons-digester3-3.0.jar和 commons-digester-2.1.jar删除掉，换成
              commons-digester-1.8.jar即可，原因是WebLogic自带的xml解析器与apache的
              commons-digester-2.1.jar以上的版本冲突，WebLogic不能兼容太高版本的xml解析器。
