I was following along Lucas’s rubycookbook receipe 15.1 for creating a  
ROR application for displaying the o/p of dir command on a windows  
machine onoto a browser.

my application is named “check” instead of “status” as given in  
receipe.

my C:/Documents and  
Settings/ri004902/check/app/controllers/check\_controller.rb … file  
looks as  
…  
class CheckController \< ApplicationController  
def index  
time = Time.now  
@time = time  
@dr = exec “dir/p”  
end  
end  
…  
and my C:\Documents and  
Settings\ri004902\check\app\views\check\index.rhtml … file is  
…

# Directory structure at \<%= @time %\>

\<%= @dr %\>

.....................................................

I start the webbrick and point my brwser to  
[http://localhost:3000/check/](http://localhost:3000/check/)

what i get is  
Application error (Rails)

I tried with @dr= ‘dir/p’ in index of CheckController … but in vain.

could anyone provide me a lead.

Cheers
