This chapter specifies the requirements for an application that is realistic enough to show how the Spring Framework can be used to develop a modern web application. If you have read Expert One-on-One J2EE Design and Development by Rod Johnson, you will recognize this example. We are using the same example, with some minor adjustments, to show the progression from the Interface21 framework presented in Rod's earlier book to today's Spring Framework.
The sample application has been designed from a business perspective. We will show you how to translate these business requirements into a fully functioning web application using features provided by the Spring Framework.
