Have the Wrox guide, but still having problems getting my hello world to
run (very frustrating!
Dirk
After creating the project directories, I created my
\app\controllers\greeting_controller.rb file:
class GreetingController < ApplicationController
def greeting
end
end
Then put in my \app\views\greeting.rhtml page:
<html>
<head>
<title>Greeting Page</title>
</head>
<body>
<h1>Hello, this is my Greeting Page</h1>
</body>
</html>
After starting the project web app. in Mongrel and connecting here:
http://localhost:3000/greeting/greeting
I get the following error:
NameError in GreetingController#greeting
uninitialized constant ApplicationController
How is this base class initialized? I must be leaving something very
basic out,
Thanks for helping!

When you created the project, a file named "application.rb" should
have been created in app/controllers. This file defines the
ApplicationController class.

Thank you so much! Yes, a silly error, I have just confirmed and it now
works. It's not yet so well documented in Wrox "Beginning Ruby on
Rails"
Thank you again,
Dirk
Installed latest InstantRails package for
Windows (XP). Thank you so much for helping!!
