Deployment problem with apache + fastcgi

Hi! I'm from Russia. It's my first post in this forum. Execuse for my
bad language, but i hope you're help me!
I try to deploy rails app on apache + fastcgi hosting.

.htaccess file contents:

AddHandler fcgid-script .fcgi
AddHandler cgi-script .cgi

Options +FollowSymLinks +ExecCGI

RewriteEngine On
RewriteRule ^$ index.html [QSA]
RewriteRule ^([^.]+)$ $1.html [QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]

Dispatch.fcgi file contents:

#!/usr/local/bin/ruby
require File.dirname(__FILE__) + "/../config/environment"
require 'fcgi_handler'
RailsFCGIHandler.process! '/var/log/myapp_fcgi_crash.log'

For request: http://mydomain/
i get "welcome ruby on rails page" with information about Rails, Ruby,
Gems versions.

I renamed index.html in public directory and wrote default "root"
controller in routes.rb. But there was an error.
I get only:

NameError in [ControllerName]#[ActionName]
uninitialized constant [ControllerName]

It was for all controllers (for all requests).
