When you first create a WebObjects project, you will have just one 'Component', the 'Main' one.
A WebObjects component consists of a folder and a bunch of files, but at this stage we're really only interested in 2:
- Main.wo - which contains the interface
- Main.java - where we'll put the logic for the Main.wo page.
Double-click on the 'Main.wo' file to edit the interface in WebObjects Builder.
