ciao
io utilizzo apache 5.5.15 e vorrei utilizzarlo per contenere pagine jsp che utilizzano javabean
come va configurato il file web.xml pe supportare le bean??
il mio è questo:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app></web-app>
la mia DateTime.class è nella certella WEB_INF\classes\date...e nel file jsp la richiamo così:
<jsp:usebean id= “dateTime” class = “date.DateTime” />
<body style = “font-size: 16pt;”>
Oggi è <jsp:getProperty name = “dateTime” property
= “date”/ >
chiedo questo perchè quando tento di utilizzarle mi da questo errore:
HTTP Status 500 -
