This
JSP
is implemented using the RichFaces tag libraries. This
JSP
lists all details
for the selected album
B
. We have two button declarations: the Purchase button
C
and the Cancel button
D
. We use RichFaces components to declare these but-
tons and to implement Ajax behavior. Notice the
reRender
attribute in the defini-
tion: this attribute holds the
ID
of another component that needs to be rerendered
when we get the response from the server. In our case, the rerendered component
is a text component that displays the status of the purchase
E
.
