Hola, soy programador autodidacta y estoy desarrollando un proyecto, consiste en un sistema para registrar a nuevas personas utilizando Java JSP y MVC, y quisiera que en la vista add.jsp aparezca el formulario un botón para cargar archivos pdf, también que ese archivo se pueda visualizar desde la vista lista.jsp. Ya llevo algunos días investigando pero no puedo, puedo programar el código html, el botón y todo eso, pero no realizar la acción. También intenté añadiendo librerías pero no funciona.
Este es el código:
Lista.jsp
<%@page import="java.util.Iterator"%>
<%@page import="Modelo.Persona"%>
<%@page import="java.util.List"%>
<%@page import="ModeloDAO.PersonaDAO"%>
