Running 2 application at the same time

Hey,

I have this hosting http://www.aloefit.be/, this is my first RoR website
(the path is /). Now I have second website “Dinotra”, and I asked the
hosting helpdesk where to put it. They told me to put it in
/public/dinotra
So I have /public/dinotra/app, /public/dinotra/config/,… And surf to
http://www.aloefit.be/dinotra/public but I cant reach the page.

I have also tried http://www.aloefit.be/dinotra/
then i get:

Routing Error

Recognition failed for “/dinotra/”

When I look at the log I have

Logfile created on Mon Nov 13 07:45:38 CET 2006 by logger.rb/1.5.2.7

ScopedAccess: reset []
FrontEndController: missing default helper path front_end_helper
You have a nil object when you didn’t expect it!
The error occured while evaluating nil.downcase
/usr/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action_controller/request.rb:18:in
`method’

These are my application controllers:

I have an application controller with 2 other controllers:

class ApplicationController < ActionController::Base
end
class FrontEndController < ApplicationController
around_filter ScopedAccess::Filter.new(Fsdocument, :publish)
around_filter ScopedAccess::Filter.new(Fsimage, :publish)
#around_filter ScopedAccess::Filter.new(ModulePermission, :publish)
around_filter ScopedAccess::Filter.new(Product, :publish)
around_filter ScopedAccess::Filter.new(Album, :publish)
around_filter ScopedAccess::Filter.new(AlbumCategory, :publish)
#around_filter ScopedAccess::Filter.new(Role, :publish)
#around_filter ScopedAccess::Filter.new(User, :publish)
around_filter ScopedAccess::Filter.new(Faq, :publish)
around_filter ScopedAccess::Filter.new(FaqQuestion, :publish)

protected
def publish
{
	:find   => {:conditions => ['publish = 1 AND (publish_from is null OR 

publish_from <= ?) AND (publish_to is null OR publish_to >= ?)',
Date.today, Date.today ]},
}
end
end
class BackEndController < ApplicationController
end

Then i have an application helper

module ApplicationHelper
end
And
module Backend::ProductsHelper
end
module Frontend::ProductsHelper
end

The other controllers I have are like this;
class Backend::ProductsController < BackEndController
end
class Frontend::ProductsController < FrontEndController
end

This works perfect local, but why does I get “missing default helper
path front_end_helper” then??

Does anyhas any exp with 2 app at the same time, they go to the same db:
Application 1 => config.active_record.table_name_prefix = “a_”
Application 2 => config.active_record.table_name_prefix = “d_”

Because I can only have 1 database.

Thx.
