Hello,
I am trying to do the following:
On startup of my application, create an EJB Timer (javax.ejb.Timer) using the
EJB TimerService (javax.ejb.TimerService).
The timer bean that I am trying to install is a stateless session bean.
I initially tried to use @PostConstruct on a method that would use the
TimerService (@Resource private TimerService timerService) to create my timer.
This didn't work immediately, so I figured, no instances of my stateless
session bean have been created - fine, I turned to @Startup to create bootstrap
component that gets a handle to the stateless session bean and invokes its
starter method. Now I'm not sure what dependencies I need to add to the
@Startup(depends={...}) list.
I know that I need the following resources available before my @Startup
component's @Create method is called:
- my stateless session bean needs to be deployed
- the persistence context for my EJB jar needs to be available for injection
I've noticed that the @In annotation doesn't seem to work for my @Startup
component (i.e. I can't get a reference to my stateless session bean); so I
looked up the reference manually:
| MyBean myBean = null;
| try {
| myBean =
(MyBean)Naming.getInitialContext().lookup("my-ear/MyBean/local");
| mailReader.startReading();
| } catch (NamingException e) {
| log.error(e,e);
| }
|
I can get a reference but invariably some other dependency fails (a @Factory
component, etc...).
Is there someway of telling @Startup something to the effect of:
"start me up after everything else" ?
Is there a better way of installing a timer in Seam?
Thanks,
Brad Smith
