I am just learning some about web service. But many guys still use Java (Jws). But I wanna try ROR. There are less information about it. I can’t get install plugin in the ROR 2.0.x. So I followed the standard textbook(“Agile\_Web\_Development\_With\_Rails-2nd” and “Ruby on Rails for PHP and Java Developers”) I almost finished it. However, I can’t find my api ([http://localhost:3001/hello/api](http://localhost:3001/hello/api) : GET not supported). Anybody can help me? Many thanks. I wanna invoke simple web service from client(3000) to Server(3001, web service in) ## I start localserver: [http://localhost:3000/helloadmin](http://localhost:3000/helloadmin) Hello Web Service This rails application tests a web service. Name:( ) ## Get Message submit and get errors: * * * * * * NameError in HelloadminController#getMsg\_client uninitialized constant HelloadminController::HelloApi RAILS\_ROOT: ./script/…/config/…
