Thanks for your opinion Jeff. I agree that DAO and Impl so in controller. Right now I have a delegate pattern which delegates the calls to DAO from the service layer.
More clearly... I have a view layer, model layer Model layer has all the Abator generated code, View has all the beans, handlers. Controllers are the services, which in turn call the DAOs In handlers would it be a good idea to create an example and pass it to the service layer or pass a view bean and create the example in the service layer? I want to have the modularity of pulling out each layer with minimum changes in the other layers. Even if I forego iBatis I can use Account.java as a dto. But can I use the DAO/Impl and example? If I cannot, what would be the better approach?

AccountDAO and AccountDAOImpl are service classes - to be used by the controller layer. Ultimately, my view is that these are all utility classes to be used by the real MVC classes in your app. If you forego iBATIS in the future, then AccountExample will be of little use to you - it is very coupled to iBATIS.
