Thanks for the answer!! Now I know how to manage the requests.
But I have a little detail. When I make a reference to one jsp file inside a servlet, I have to write the full path, by example: getRequestDispatcher("/WEB-INF/views/result.jsp"). Is there any way of make a "logical reference" to the jsp file? Or the best is to add the path manually? for example:
static String prefix = "/WEB-INF/views/";
static String sufix = ".jsp";
getRequestDispatcher( prefix + "result" + sufix)
The goal is to write only: getRequestDispatcher("result")
Thanks a lot,
Fran
