Applications and Projects

• An application in WebLogic Workshop is the
  collection of all resources and components that
  are deployed as a unit to an instance of WebLogic
  Server. It is also the top-level unit of work
  that you manipulate with WebLogic Workshop IDE.
  An application in WebLogic Workshop contains one
  or more projects. Components in the projects of
  an application may reference each other, but they
  may not generally reference components in other
  WebLogic Workshop applications.

35
Overview of the Store application

• The store application maintains the information
  about companies and their products that are
  available from a Store.
• Company and Product are entity beans
• There is a 1N relationship between Company and
  Product.

36
Overview of the Store application (contd.)

• Store is a session bean that manages Company and
  Product entities. It acts as the interface for
  client (JSPs)
• It also acts as a message producer and produces
  order message
• ProductOrders is a message driven bean that
  receives messages sent by Store and updates the
  appropriate Product with the information in the
  received message.

37
Bean summary

• Company entity bean- holds information about the
  companies.
• Product entity bean- holds information about
  various products.
• Store session bean- references the Company and
  Product entity beans, and provides the interface
  to client applications. Sends messages about the
  orders to the ProductOrders bean .
• ProductOrders message-driven bean- processes
  messages sent by the Store bean.

Interaction between the bean components

Information about Client Jsps

• Menu.jsp Facilitates the options for the user
  to either manage companies or manage products
