Good afternoon everyone,
I have a question about the ejb timer services with the new singleton
beans. What I want to do is create a timer service that starts on
openejb startup, so I thought it would be perfect to use the singleton
bean for this purpose. However, when I try to create the timer in the
singleton post-construct method, I get this error:
java.lang.IllegalStateException: TimerService method not permitted for
current operation POST_CONSTRUCT
Is this a bug, an incomplete implementation, or by design? I suppose I
can work around by using a servlet context listener, but I figured
singleton beans would be cleaner.
-----------------------------------------------------------------------------------------------------
Here is my singleton class:
@Singleton(name="TimerServiceTest")
@Startup
public class TimerServiceTestBean implements TimerServiceTestLocal {
private static Logger _log =
Logger.getLogger(TimerServiceTestBean.class);
private volatile static Timer _timer;
@Resource
private TimerService _timerService;
@PostConstruct
public void onStartup() {
_timer = _timerService.createTimer(60000, 60000, null);
_log.info("Starting TimerServiceTestBean timer.");
}
@PreDestroy
public void onShutdown() {
_timer.cancel();
_log.info("Shutting down TimerServiceTestBean timer.");
}
@Timeout
public void onTimeout(Timer timer) {
_log.info("TimeServiceTestBean has just received a timeout
notice at "
+ (new Date()).toString());
}
}
