Ciao a tutti. Da un'ora sto impazzendo per un programmino semplice ( sto appena imparando java).
In Teoria da una pagina jsp voglio collegarmi a un servlet attraverso il web.xml.
In pratica non va e non capisco!!!!

la servlet
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class sendMail extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("SERVLET");
}
}
[Allego anche l'immagine delle cartelle.
