In this tutorial, you will learn how to create a simple Struts application that contains two Web pages, an action mapping, and a form bean. You will use the Web diagram editor to help you visualize the logic flow of the application. The resulting application displays an input Web page where users can type a year, a month, and a date. If the input is valid, the corresponding day of the week is computed and shown on an output Web page. If the input is invalid, an error message is displayed on the input Web page. You will also learn how to set up a runtime test environment and test your application.
