If you are going for the MVC approach the you probably want your JSPs to be under the WEB-INF folder. It makes sense there as you do not want people accessing your jsps directly without going through a Servlet. For example your servlet may load some data from the database and put it in the request so that your JSP page can then display it.
If you were able to access the JSP directly then you'd just get some nasty looking error message because the data would not be there, not very professional.
