Ruby on Rails

I am developing an application in rails 3.2 with gem jquery-rails. I am using development mode, but will change to production soon. Then this error which I get in development mode -- No route matches [GET] "/jquery/ui-bg_flat_75_ffffff_40x100.png") -- had to be fixed. Jqueru-ui has a rule with url(../jquery/ui-bg_flat_75_ffffff_40x100.png) that does not work in my environment. I have tried to correct it in my own jquery file but it is still there, I have disabled my own jquery-ui files but I still get the error and jquery-ui works in the application. My conclusion is that jquery-ui is loaded outside my application or it is a caching problem. How can I change the url in this jquery-ui that I cannot control? How can I empty the cash ( I am using appach)? How is jquery-ui loaded when only gem jquery-rails is used?  I have also tried to use the other different gems that should take care of jquery-ui but I still get the same error.
Any Help would be very appreciated !!
