Project Architecture for interview

HI ,am newbie for web development. I want project architecture(for EXample hospital management system project).
Technologies used are java 1.5, jsp, servlet, struts, hibernate and back end oracle. I need flow of control with dao files

I think you put the cart before the horse - you seem to have made implementation decisions (like which libraries to use) before having an architecture. That's not how one goes about software development.

You might want to look for the MVC pattern which is one of the most frequently used. And the Struts itself implements MVC with more features so you can start there. But as you mentioned a particular application, there is no such architecture for a particular type of application defined. But there are design patterns, best practices etc.. can be combined to form a design/architecture to suit the business problem you are trying solve.

I need flow of control with dao files

DAO (Data Access Object) pattern is used to abstract and encapsulate the real data access code and provide an interface for the upper layers of the application.

Please see ShowSomeEffort, DoYourOwnHomework, and NotACodeMill (although in this case it would be more accurate to have a "Not a design mill" entry).

I actually don't understand what you mean by "flow of control" in this context--that's not what "project architecture" means to me.
