Question

Hello I am destar John.
 
I want to know About getting report from reporting web service.I do some instructions of telling me online change so I change it whatever it change,it says
"The attempt to connect to the report server failed.Check you connection information and that the report server is a compatible version.
the request failed with HTTP status 404:Not Found."
 

whatever I change it.
I make step by step from some learning video exactly.but they can connect and I can't get them(Reports) from Reporting Web Service.
I think I need some configuration with RSWebApplication.config and rsreportserver.config.
can anyone show me the full configuration of these two and simple Project?
