Newbie:: spring mvc layout

[jbluedelta]

ScreenShot054.jpgTrying to get a better understanding of the directory structure layout in windows of spring mvc project.

The project I have has the following directory structure

MyTestProject
- src
- main
- java
- com
- companyname
- beans
- commands
- controllers [understand this one]
- mappers
- resolvers
- services
- views [understand this one]

- resources
- webapp

If i look in the beans and commands directory, the objects look similar to me. also what goes in services and other directory? Could not find the info on the documentation or i may have missed it.

any help is appreciated.
