Ciao
Ho creato il seguente package java\:
---------------------------------------------------------------
package alfa;
public class Prova
{
String nome;
public String setProva()
{
nome="PIPPOPLUTOOOO";
return nome;
}
}
----------------------------------------------------------------
l` ho compilato e inserito all` interno diella directory classes di tomcat dentro ad una directory "Prova".
poi dalla pagina JSP ho richiamato il bean con la seguente sintassi:
---------------------------------------------------------------------
<html>
<head><title>Utilizzo del Bean</title></head>
<body>
<jsp:useBean id="ciao" class="Prova"/>
</body>
</html>
--------------------------------------------------------------------
ma mi da questo errore:
HTTP Status 500 -
--------------------------------------------------------------------------------

Qualcuno sa dirmi come devo fare per farlo funzionare?
Avrei urgente bisogno di risolverequesto problema...
