JSP does not recognize servlets

I am developing a project in jsp with Netbeans (I have already developed several) but in this unlike the previous ones that I have developed I have decided to organize the code much better by classifying it in folders (the jsp files inside the root folder which is the web folder) but when doing this I realize that in this way the servlets are not recognized. I did the test by moving one of those files to the root folder (web) and immediately upon filling out the form, I recognized the servlet. The question is, is there any way to recognize the servlets and continue with the organization of the code? I really do not want to have all the jsp files in the same folder for organizational reasons.

java jsp servlets

Be sure to call the servlets by their absolute path, not their relative path.

Example:

Folder structure:

src
  - edu.ltmj.servlets
    + MiServlet.java
web
  + index.jsp
  - WEB-INF
    - mi
      - carpeta
        - de
          + vista.jsp

Servlet:

@WebServlet("/MiServlet")
public class MiServlet extends HttpServlet {
    @Override
    public void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

        String nombre = request.getParameter("nombre");
        request.setAttribute("nombre", nombre);
        request.getRequestDispatcher("WEB-INF/mi/carpeta/de/vista.jsp")
            .forward(request, response);
    }
}

index.jsp (omission head and body for brevity of the code):

<form action="/MiServlet">
    <label for="nombre">Ingresa nombre</label>
    <input type="text" name="nombre" id="nombre" placeholder="Nombre" />
    <input type="submit" value="Saludar" />
</form>

vista.jsp

Hola ${nombre}. Saludemos a alguien más.
<form action="/MiServlet">
    <label for="nombre">Ingresa nombre</label>
    <input type="text" name="nombre" id="nombre" placeholder="Nombre" />
    <input type="submit" value="Saludar" />
</form>
