how to run multiple jobs in quartz scheduler in struts - scheduler

Question

I implemented multiple jobs in quartz scheduler as a plugin in struts but only first job is running by using the tutorial from http://www.mkyong.com/struts/struts-quartz-scheduler-integration-example/
public class QuartzPlugin implements PlugIn {
private JobDetail job = null;
private Trigger trigger = null;
private Scheduler scheduler = null;
private static Class<QuartzPlugin> clazz = QuartzPlugin.class;
public static final String KEY_NAME = clazz.getName();
private static Logger logger = Logger.getLogger(clazz);
#Override
public void destroy() {
try {
String METHODNAME = "destroy";
logger.debug("entering " + KEY_NAME + " " + METHODNAME);
scheduler.shutdown();
} catch (SchedulerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
#Override
public void init(ActionServlet servlet, ModuleConfig modConfig) throws ServletException {
String METHODNAME = "init";
logger.debug("entering " + KEY_NAME + " " + METHODNAME);
job = JobBuilder.newJob(SchedulerJob.class).withIdentity("anyJobName","group1").build();
try {
trigger = TriggerBuilder.newTrigger().withIdentity("anyTriggerName", "group1")
.withSchedule(CronScheduleBuilder.cronSchedule("0/30 * * * * ?")).build();
scheduler = new StdSchedulerFactory().getScheduler();
scheduler.start();
servlet.getServletContext().setAttribute(KEY_NAME, scheduler);
// define the job and tie it to our HelloJob class
JobDetail job2 = JobBuilder.newJob(HelloJob.class).withIdentity("job2", "group2").build();
// Trigger the job to run on the next round minute
Trigger trigger2 = TriggerBuilder.newTrigger().withIdentity("trigger2", "group2")
.withSchedule(CronScheduleBuilder.cronSchedule("15/45 * * * * ?")).build();
// Tell quartz to schedule the job using our trigger
scheduler.scheduleJob(job, trigger);
scheduler.scheduleJob(job2, trigger2);
} catch (SchedulerException e) {
e.printStackTrace();
}
}
}
