Spring MVC development process - best practices

What is the right development process of Spring MVC / portlet-MVC application using JSPs as a view layer, when we don't take service/DAO layer in account - it is usually done already.

I mean, if I'm creating controller + JSP(s) at a time, I'm getting kinda lost in a while and everything seems a mess, I'm loosing the overall survey about the application design and requirements. But on the other way I can't imagine that I would create JSPs at first and then controllers or controllers at first and then JSPs.

Programming portlets is much more complicated and having this resolved seems im开发者_如何学Goportant.

Note: Consider no development team (graphic designer + programmer), I'm doing all by myself...

I start by declaring the most significant areas, within the entire portlet plugin I'm about to develop, from both technology and "business logic" point of view. I usually assign one controller for each such area.

HTML form          -  Controller - InternalResourceViewResolver   - JSP
Common rendering   -  Controller - InternalResourceViewResolver   - JSP
Ajax component     -  Controller - BeanNameViewResolver           - YUI + JSP + JSON

I like the iterative style of programming. Create the "skeleton" that it is acceptable to monetize it. And then I spend 2 times more time by making it fancier.
