Hi there,
I want to use the timer service in my EJB.
But when I use the following code
[...]
@Stateless
public class MyClass {
@Resource
private javax.ejb.TimerService timerService;
[...]
}
I always get the following exception during deployment:
SEVERE: Exception while deploying the app [ETFS-NGEAR] : nullat org.glassfish.apf.AnnotationInfo@264c6afe

When I comment out the @Resource annotation it deploys but obviously timerService is null.
If I use an automatic timer with @Schedule(...) the application deploys without any errors and works as expected.
What's wrong with my approach???
Kind regards
