Spring's Building a RESTful Web Service tutorial could use more details on directory structure

[akanshmurthy]

It is not clear where each file should be stored and what folder should house what files. It's not explicitly mentioned and would make the tutorial easier to follow if it did. For instance, indicating that the src/main/java/hello resides within an enclosing folder and that the pom.xml resides that enclosing folder as well.
