Creating a Simple WebObjects Application

---

The basic steps involved in creating a WebObjects application are:

• Create a new application directory.
• Enter static text.
• Add elements to the page.
• Set bindings for the dynamic elements.
• Write script to customize the dynamic elements.
• Run the application.

You perform these steps using an application called WebObjects Builder. This chapter teaches you how to create a simple application using WebObjects Builder. The application you'll write implements a guest book. It contains a form that has fields in which guests enter their names, e-mail addresses, and comments. Guests enter all pertinent information and then click Submit. When this button is clicked, the guest is added to a list of guests, the page is redrawn, and the new guest appears at the bottom of the list.
