With this resource hierarchy set up, here's what you should expect:


  - / will call root.getChild("")
  - /id will call root.getChild("id")
  - /foo/bar will call root.getChild("foo").getChild("bar")

So, perhaps you want to make root an instance of Root instead of an 
instance of Resource with a "" child of a Root instance?
