Action Controller : Exception Caught

I had opened an existing ROR project in Netbeans 7.0. (Rails 3.1.3/Ruby
1.9.3) I was able to open the index home page of the project after
compiling and and uploading to Webrick server. After I enter the URL as:
http://localhost:3000/attachment/attach (server/controller/view-file), I
receive a Routing Error (No route matches [GET] "/attachment/attach").
The webpage indicates a Action Controller : Exception Caught.

How should I resolve this issue? Do I need to run something like
"generate" to link the view files to the controller?

You probably need to specify a route in routes.rb if there is not one
already. Have a look at the Rails Guide on Routing. However if this
is supposed to be an existing app that did work then it should already
have the route.
After modifying routes.rb you need to restart the server.
