Hi Tom,

Does this mean you could have more then one @ProcessMethod with differend parameters where the kind of payload will activate the right one for the job?

I will illustrate: Say you have differend kinds of orders: orders-send-by-mail, orders-picked-up-at-location and express-orders. All these orders are converted by unmarshalling it from XML to Java-objects. Then the actionclass would look like:


public class HandleOrderAction{


   @ProcessMethod

   public OrderAcknowledgment processOrder(MailOrder purchaseOrder){     // Do your thing with the order...

     return new OrderAcknowledgment(....);
   }


@ProcessMethod

   public OrderAcknowledgment processOrder(PickupOrder purchaseOrder){     // Do your thing with the order...

     return new OrderAcknowledgment(....);
   }


@ProcessMethod

   public OrderAcknowledgment processOrder(ExpressOrder purchaseOrder){     // Do your thing with the order...

     return new OrderAcknowledgment(....);
   }


}



So when an expressorder is placed, the processmethod will call the method with the ExpressOrder as incoming parameter, when a mailorder is placed the method will be called with the MailOrder parameter and so on.

Will this work or is this possible in any way?

regards,

Hans
