The input text field takes a payment amount, passed to
paymentBean.value
. Two ra-
dio buttons ask the user to select a Debit Card or Credit Card payment, passing the integer
value to
paymentBean.paymentOption
. Finally, the Pay command button's action
is set to the method
paymentBean.pay
, while the Reset button's action is set to the
paymentBean.reset
method.
The
payment.PaymentBean
managed bean uses qualifiers to differentiate between
the two kinds of payment event:
@Named
@SessionScoped
public class PaymentBean implements Serializable {
...
@Inject
@Credit
Event<PaymentEvent> creditEvent;
@Inject
@Debit
Event<PaymentEvent> debitEvent;
The qualifiers,
@Credit
and
@Debit
, are defined in the
payment
package along with
PaymentBean
.
Next, the
PaymentBean
defines the properties it obtains from the Facelets page and will
pass on to the event:
