    QuartzScheduler on Tomcat: "Group name cannot be empty"

    empinator Feb 28, 2010 6:11 PM

      Hi,


      I'm trying to get the Quartz Scheduler in my Seam Application working.
      Whenever I boot the application and it's trying to initialize the TriggerHandle I get the exception Group Name cannot be empty.


      I have no idea what I am doing wrong.


      I would appreciate any hints



      •   quartz.jar is included in WEB-INF/lib (Version 1.4.3)

      • async:quartz-dispatcher tag is in my components.xml

      • seam.quartz.properties is under WEB-INF/classes

      • running Seam 2.2.0.GA on Tomcat 6.0.



      This is my code


      @Name("controller")
@AutoCreate
@Scope(ScopeType.APPLICATION)
public class ScheduleController implements Serializable {
    @In
    private SchedulerProcessor processor;
    @Logger
    private Log log;  

    private QuartzTriggerHandle quartzTestTriggerHandle;
    private static String CRON_INTERVAL = "0 * * * * ?";

    @Observer("org.jboss.seam.postInitialization")
    public void scheduleTimer() {
        log.info("Creating Cronjob");
     quartzTestTriggerHandle = processor.createQuartzTestTimer(new Date(), CRON_INTERVAL);
    }
}

@Name("processor")
@AutoCreate
@Scope(ScopeType.APPLICATION)
public class SchedulerProcessor {

    @Asynchronous
    @Transactional
    public QuartzTriggerHandle createQuartzTestTimer(@Expiration Date when, @IntervalCron String interval) {

        triggerStatusmail();

        return null;
    }
    ...
}




      The Exception:
