Routing error when running Rails 3 application server in production mode

I was developing a Rails3 application and I wanted to execute a bunch of JavaScript code only on production server. So, in order to do that in my view I added these lines:

<%- if RAILS_ENV == "production" -%>

      -- my JavaScript code --

<% end %>

Now, I wanted to test the code before deploying it on production. So, I needed to start the Rails server in production mode. To start a Rails3 application server in production mode, I passed '-e production' parameter as:
rails s -e production

But when I started browsing the application, all the stylesheets, images were gone and was getting Routing errors similar to the one given below:
Started GET "/javascripts/jquery.js?1303373839" for 127.0.0.1 at Thu May 05 19:55:09 +0530 2011

ActionController::RoutingError (No route matches "/javascripts/jquery.js"):

Reason was - Rails defaults not serve static assets in production, so to fix Routing Errors, I changed

config.serve_static_assets = false

line in 'config/environments/production.rb' to
config.serve_static_assets = true

And restarted the server in production mode. It solved the Routing issue.
