File
De sc rip tio n
index.html
This is the default home page for the bookstore, which is displayed by entering the
following URL in the client’s Web browser:
http://localhost:8000/advjhtp1/store
styles.css
This Cascading Style Sheet (CSS) file is linked to all XHTML documents rendered
on the client. The CSS file allows us to apply uniform formatting across all the
XHTML static and dynamic documents rendered.
books.jsp
This JSP uses
BookBean objects and a TitlesBean object to create an
TitlesBean object
queries the books database to obtain the list of titles in the database. The results
are processed and placed in an ArrayList of BookBean objects. The
XHTML document containing the product list. The
list is stored as a session attribute for the client.
BookBean.java
An instance of this JavaBean represents the data for one book. The bean’s
getXML method returns an XML Element representing the book.
TitlesBean.java
JSP
BookServlet.java
This servlet (aliased as displayBook in Fig. 11.1) obtains the XML
representation of a book selected by the user, then applies an XSL transformation
to the XML to produce an XHTML document that can be rendered by the client. In
this example, the client is assumed to be a browser that supports Cascading Style
Sheets (CSS). Later examples in this book apply different XSL transformations for
different client types.
books.jsp uses an instance of this JavaBean to obtain an
ArrayList containing a BookBean for every product in the database.

11.2 Bookstore Architecture (Cont.)
book.xsl
This XSL style sheet specifies how to transform the XML
representation of a book into an XHTML document that
the client browser can render.
CartItemBean.java
An instance of this JavaBean maintains a BookBean and
the current quantity for that book in the shopping cart.
These beans are stored in a HashMap that represents the
contents of the shopping cart.
AddToCartServlet.java This servlet (aliased as addToCart in Fig. 11.1)
updates the shopping cart. If the cart does not exist, the
servlet creates a cart (a HashMap in this example). If a
CartItemBean for the item is already in the cart, the
servlet updates the quantity of that item in the bean.
Otherwise, the servlet creates a new CartItemBean
with a quantity of 1. After updating the cart, the user is
forwarded to viewCart.jsp to view the current cart
contents.
viewCart.jsp
This JSP extracts the CartItemBeans from the
shopping cart, subtotals each item in the cart, totals all the
items in the cart and creates an XHTML document that
allows the client to view the cart in tabular form.
order.html
When viewing the cart, the user can click a Check Out
button to view this order form. In this example, the form
has no functionality. However, it is provided to help
complete the application.
process.jsp
This final JSP pretends to process the user’s credit-card
information and creates an XHTML document indicating
that the order was processed and the total order value.
