Creating a Compiled Application

This chapter shows you how to use Project Builder and WebObjects Builder to include compiled code in a WebObjects application. The application you'll create in this chapter is called Registration. The first page of the Registration application looks like this:

Registration is similar to the GuestBook application that you created when you worked through the first tutorial in this book, but it's a little more complex. Registration has these additional features:

• It validates the information that the users enter.
• The list of registrants persists between invocations of the application.
• It has multiple submit buttons.
• It has more than one component.
