Hi!
I've done some extensive work with servlets. Now i'm doing jsp.
The jsp model 2 architecture specifies that use
jsp for presentation
servlet as the controller
java bean for business logic.
My question is what if i put all business logic in servlet and do not use java beans??
Can we do away with java beans?

Of course it depends on what you want to do.
The important thing is (and I think you got it) the clear separation of presentation (JSP) and logic or as I call them, calculations needed by the Web Application.
Your bean vs. servlet question is hard to answer if we don't know the complexity of the "calculations".
Of course a Servlet can do it. The question is "Reusability". If you need it, then beans are the answer. IF not, maybe the servlet can do a one-time processing of data.
My experience says that reUsability is more important
