Hello Friends,

Sorry for my bad english.I am a rails novice. I successfully install  
rails 2.0.1 and activerecord 2.0.1 in my windows Xp sevice pack 2  
system. I am trying to develop simple rails application which does not  
require database. 1st i type from my command prompt:

rails myapp

then I create a controler :

myapp/script\>ruby generate controler hi index

after that i start the webbrick server:

myapp/script\>ruby server

but when I brows from IE [http://localhost:3000/hi](http://localhost:3000/hi) it gives me the  
folloing mysql error:
