Enterprise Beans Used in Duke's Bookstore
Two enterprise beans located in the
dukesbookstore.ejb
package provide the busi-

BookRequestBean
is a stateless session bean that contains the business methods for
the application. The methods create, retrieve, and purchase books, and update the invent-
ory for a book. To retrieve the topics, the
getBooks
method calls the
findBooks
named query defined in the
Book
entity.
ConfigBean
is a singleton session bean used to create the topics in the catalog when
the application is initially deployed. It calls the
createBook
method defined in
BookRequestBean
