Could not find table 'sessions' in rails 3.0

i am in the process of upgrading my ruby application with rails 3.0
which was previously running in rails 1.2.3, this application is used
only to consume a webservice so i dont need any model for this, so i
created only controllers and views, when i run the application i am
getting the following error

ActiveRecord::StatementInvalid in Websamples/ap/setpayController#set_pay

Could not find table 'sessions'

i googled for sample rails 3.0 application but i couldn't find any
application without using models

can anyone help me on this?
