Java Platform, Enterprise Edition (Java EE) 8
The Java EE Tutorial
Duke’s Bookstore is a simple web application that uses many features of JavaServer Faces technology, in addition to other Java EE features:
JavaServer Faces technology, as well as Contexts and Dependency Injection for Java EE (CDI)
A set of Facelets pages, along with a template, provides the user interface to the application.
CDI managed beans are associated with each of the Facelets pages.
A custom image map component on the front page allows you to select a book to enter the store. Each area of the map is represented by a JavaServer Faces managed bean. Text hyperlinks are also provided for accessibility.
Action listeners are registered on the image map and the text links. These listeners retrieve the ID value for the selected book and store it in the session map so it can be retrieved by the managed bean for the next page.
h:dataTable tag is used to render the book catalog and shopping
cart contents dynamically.
A custom converter is registered on the credit card field on the
bookcashier.xhtml, which also uses an
tag to ensure that the input is correctly formatted.
A value-change listener is registered on the name field on
bookcashier.xhtml. This listener saves the name in a parameter so the
bookreceipt.xhtml, can access it.
