Hi All,

In struts-2, how to use DAO layer which communicates with DB. I don't know if DAO layer comes, then what is the function of Model. Now, in my application, I've bean with setters and getters, Model which is responsible for communicating with DB and retrieving DB. Action classes which validates client side input. Can anybody give me a proper structure of struts-2 with DAO layer?

The major components of Struts 2 do not exactly map to the MVC pattern. This article has a typical MVC overlay of Struts. As far as Struts is concerned, the controller is the dispatcher and interceptors. For a non-trivial Struts application, I would maintain there will be a fair amount of controller logic in the Action and the Model is usually pushed into a JavaBean. The Action then uses the DAO to obtain the appropriate Model instance for what the View has requested..
