I have deployed my Ruby on Rails Application on Torquebox. After starting server I am getting this error

回答1:
It looks like you have the trinidad gem in your Gemfile. That gem isn't needed under TorqueBox, and probably won't load properly. Try removing trinidad as a dependency and see if that helps. If not, come see us in irc (#torquebox on freenode) or on the mailing list and we'll give you a hand.
