Ciao
Ho un prob. ho utilizzato il java bean che cè nella lezione 14 di jsp presente su questo sito, ma quando lo inserisco nella pagina jsp la pagina al caricamento mi da errore. Uso una conessione sicura SSL sulla porta 8443 funzionante. Utilizzo Tomcat.
la riga che inserisco è questa:
<%@ page contentType="text/html" language="java" import="Sito.*" errorPage="" session="true"%>
<html>
<head>
<title>Autenticazione con Jsp</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
....
<jsp:useBean id="utente" scope = "session" class="Utente"/>
...altro codice html..
</body></html>
e la classe che ho rinominato Utente è questa:
package Sito; -->perkè ho messo il file Utente.class nella cartella
C:\Programmi\Apache Group\Tomcat 4.1
\webapps\Sito\WEB-INF\classes\Sito
public class Utente {
private String nome = null;
private String email = null;
private int pagineViste;
public Utente() {
pagineViste=0;
}
public void aggiornaPV(){
pagineViste++;
}
public int getPagineViste(){
return pagineViste;
}
public void setNome(String value) {
nome = value;
}
public String getNome() {
return nome;
}
public void setEmail(String value) {
email = value;
}
public String getEmail() {
return email;
}
public String riassunto(){
String riassunto = null;
riassunto = "Il nome dell'utente è"+nome+",";
riassunto+= "il suo indirizzo e-mail è: "+email;
riassunto+=" e ha visitato "+pagineViste+" del sito";
return riassunto;
}
}//InfoUtente
mentre questo è l'errore che mi da al caricamento:
type Exception report
