Implementing the Show Contact View
Now we implement the view for showing a contact's information. Implementing the show view is a
three-step process:
Implement the controller method.
1.
Implement the show contact view (/views/contacts/show.jspx).
2.
Modify the view definition file for the view (/views/contacts/views.xml).
3.
Listing 17-27 shows the show() method implementation of the ContactController class for
displaying a contact's information.
