Question

I have a problem with this setup and I can’t even view the logs.

This is my @Singleton @Startup EJB:

@Singleton
@Startup
@DependsOn("SchedulerEJB")
public class SchedulerStartUp {

    private static Logger log = Logger.getLogger(SchedulerStartUp.class);

    @EJB
    SchedulerEJB schedEJB;  

    @PostConstruct
    public void atStartup() {
       log.info("startUp")
       System.out.println("startUp");

       schedEJB.cancelTimer("EBlastScheduler");
       schedEJB.createTimer("*/1", "*", "*");
    }
}

The SchedulerEJB:

 @Stateless
 public class SchedulerEJB {

    @Resource
    TimerService timerService;         

    public cancelTimer(String timerInfo){/*...*/}

    public createTimer(String sec, String min, String hour) {/*...*/}

    @Timeout
    public void execute(Timer timer) {/*...*/}
 }

Maven pom:

 //Been Using Glassfishv3.0.1 and EJB3.1 with a dependency of:
 <dependency>
     <groupId>javax</groupId>
     <artifactId>javaee-api</artifactId>
     <version>6.0</version>
     <scope>provided</scope>
 </dependency>

You have invalid type of bean as an attribute of @DependsOn. DependsOn is for expressing dependency between two Singleton session beans, not between Singleton and Stateless. You should change SchedulerEJB to be Singleton or remove dependency.

If you decide change SchedulerEJB to Singleton, then @DepensOn is also not needed, because (from EJB 3.1 specification):

Note that if one Singleton merely needs to invoke another Singleton
from its PostConstruct method, no explicit ordering metadata is
required. In that case, the first Singleton would merely use an ejb
reference to invoke the target Singleton. There, the acquisition of
the ejb reference (either through injection or lookup) does not
necessarily imply the actual creation of the corresponding Singleton
bean instance.
