Spring layers

[JavaCaravan]

I working on a project using Spring MVC. I need to make a plan where goes what e.g. the Controller class, DAO, BO (business Object), TO (transfer object), Validation classes, FormBean etc. I need to organize my project. I read that Spring MVC application is broken down into a series of layers. i.e.

1. User Interface
2. Web
3. Service
4. Domain Model
5. Persistance
6. DAO

I need to know what goes in what layer. My BO calls DAO and DAO uses TO. For each DAO class I have an Interface. I am pulling all the data from oracle by invoking back-end pl/sql procedure calls in my DAO usig JDBCTemplate. Can you tell me how should I organize my different classes (entire project) into different layers.

Thanks

I would say something like this:

Web-layer
- controllers
- validators
- FormBeans

Service-layer
- transactions
- services with interfaces
- DTO:s

Domain model
- your domain objects AKA business objects

Persistence AKA dao layer
- dao interfaces
- dao implementations
