POHow to start an EJB Timer on deployment?
text
Body
copied!<p>I need to create an interval Timer that is set to run once a week automatically. I don't want it to start based on user input, but I want it to be created when the application is deployed to the server. Every example that I have seen has another class starting the timer. I don't want to use a message driven bean to create the timer because the audit should just query a database for a given time period and is not based off of actions which send messages.</p> <p>I have included an example of a Timer. In the example below, the timer should fire every 10 minutes. As a test I want the timer to fire every 10 minutes so I can test the timer.</p> <pre><code>@Stateless public class TimerTest implements TimerTestLocal, TimerTestRemote{ @Resource private TimerService timerService; private Logger log = Logger.getLogger(TimerTest.class); private long interval = 1000 * 60 * 10; private static String TIMER_NAME = "AuditTimer"; public void scheduleTimer() throws NamingException { // TODO Auto-generated method stub Calendar cal = Calendar.getInstance(); //cal.set(Calendar.HOUR_OF_DAY, 23);//run at 11pm //cal.set(Calendar.MINUTE, 00); //cal.set(Calendar.DAY_OF_WEEK, Calendar.FRIDAY); SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm"); log.debug("schedule for: " + sdf.format(cal.getTime())); timerService.createTimer(cal.getTime(), interval, TIMER_NAME); } public void cancelTimer() { for(Object obj : timerService.getTimers()) { Timer timer = (Timer)obj; if(timer.getInfo().equals(TIMER_NAME)) timer.cancel(); } } @Timeout public void timerEvent(Timer timer) { log.debug("timer fired"); } } </code></pre> <p>So is there any way that I can start this timer when the application is deployed? I don't think it's a good idea to put the creation of the Timer in a @PostConstruct method because of class loaders on in the server.</p>

Querying!
