    Qestion about timers in jboss seam

      Hello,

      In documentation I've found that jboss seam has timer possibility. The question is, how I can initialize timer task on application deploy time. The possible way is via context listener in web.xml where I'll invoke EJB method that is represented as timer. Is there another way to initialize timer task on application start up?

      Thanks.

          Use

          @Observer("org.jboss.seam.postInitialization")

            Am I right, if I have for instance:

            @Stateful
@Name("paymentAction")
public class CreatePaymentAction
{
 @In(create=true) PaymentHandler paymentHandler;
 @In Bill bill;

 public String schedulePayment()
 {
 paymentHandler.processScheduledPayment( new Payment(bill), bill.getDueDate() );
 return "success";
 }

 public String scheduleRecurringPayment()
 {
 paymentHandler.processRecurringPayment( new Payment(bill), bill.getDueDate(),
 ONE_MONTH );
 return "success";
 }
}


            The example is taken from seam documentation.
            So, if I want to invoke method at deploy time, I have to do next: 

            @Stateful
@Name("paymentAction")
public class CreatePaymentAction
{
 @In(create=true) PaymentHandler paymentHandler;
 @In Bill bill;

 public String schedulePayment()
 {
 paymentHandler.processScheduledPayment( new Payment(bill), bill.getDueDate() );
 return "success";
 }

 @Observer("org.jboss.seam.postInitialization")
 public String scheduleRecurringPayment()
 {
 paymentHandler.processRecurringPayment( new Payment(bill), bill.getDueDate(),
 ONE_MONTH );
 return "success";
 }
}


            ?

              Yup, though you probably don't need it to be stateful.
