No it's NOT true - you can dispatch from a servlet to JSP, and that's what
you should do following MVC. The problem with your code could be the template Next.jsp being not found in the context. Since it is very unlikely that you need to allow your users directly access Next.jsp, put it somewhere in WEB-INF directory, say, for example, as in WEB-INF/templates/next.jsp . When you forward, use the context-relative path, as in
getRequestDispatcher("/WEB-INF/templates/next.jsp")
