Send a Rejection E-Mail

The only remaining placeholder is the “Send Rejection Email” service task on the rejection path. We add a rejectOrder method to OrderBusinessLogic that logs a (simulated) rejection e-mail:

private static Logger LOGGER = Logger.getLogger(OrderBusinessLogic.class.getName());

public void rejectOrder(DelegateExecution delegateExecution) {
  OrderEntity order = getOrder((Long) delegateExecution.getVariable("orderId"));
  LOGGER.log(Level.INFO,
    "\n\n\nSending Email:\nDear {0}, your order {1} of a {2} pizza has been rejected.\n\n\n",
    new String[]{order.getCustomer(), String.valueOf(order.getId()), order.getPizza()});
}

…and wire it up on the service task:

<bpmn:serviceTask id="ServiceTask_1w32ybd" name="Send Rejection Email" camunda:expression="${orderBusinessLogic.rejectOrder(execution)}">

Build and Deploy

Rebuild and redeploy the WAR file. The pizza order process is now complete end to end: placing an order persists it via an EJB service bean, approving or rejecting it is handled by CDI-scoped JSF task forms, and both paths - preparing the pizza or sending a rejection e-mail - are reachable and fully wired up.
