Simple hello world app

Hi,
I am trying to create an application which simply returns hello world. This is what I have done:

1) create service hello
- v8js simply return "hello world"
2) then I created a role "test" and gave it permission to access hello service using GET

3) I created app "HelloWorldApp" and gave access path as /test/

Then on another machine i tried to create a client and invoke HelloWorldApp (path= /test/hello) but its giving me 404 , reason=not found

Can anyone please tell me what am i doing wrong?

Thanks
