      Hi,


      I'm getting some errors when i try to schedule an asynchronous method at start up.
      I've tried using the @Startup annotation with a @Create method and I get the following errors

      the method I'm using at start up is



      //@Observer("org.jboss.seam.postInitialization")
@Create
public void startService() {
  Calendar cal = Calendar.getInstance();
  cal.add(Calendar.MINUTE, 5);
  Long repeat = 5* 60 * 1000L;
  try {
   billingTimer = billingAction.processRecurringBilling(cal.getTime(), repeat);
  } catch (Exception ex){
    ex.printStackTrace();
  }
}







      The  local interface of billingAction is



      @Asynchronous
    public Timer processRecurringBilling(@Expiration Date date,
                                        @IntervalDuration Long interval);




      When I schedule the Asynchronous method through an action method from a web page I don't get the error and everything works fine.
      I'm using JBoss 4.2.3.GA and Seam 2.0.2.SP1 using the EJB3 timer.


      Does anyone have any ideas on what's wrong or how i can schedule a task at startup?


      Regards
      Darrell

          I didn't use @Startup but my code works with EJB 3 timer or Quartz scheduling...


          using Seam 2.0.1.GA and JBoss 4.2 (EAP 4.3.0CP2_FP01)


          components.xml:


             

          <event type="org.jboss.seam.postInitialization">   
        <action execute="#{controller.scheduleTimer}"/>
   </event>
   
   <!-- Install the QuartzDispatcher -->
   <async:quartz-dispatcher/>   
  
   <!-- Install the EJB timer service -->  
   <!-- <async:timer-service-dispatcher />  -->



          controller component:


          @Name("controller")
@AutoCreate
public class ScheduleController implements Serializable { 
   
    @In ScheduleProcessor processor;    
    @Logger Log log;
