Bonjour,
J'essaie de découvrir Spring à traver le tutorial 'step by step' de Spring mvc sauf qu'à la fin du chapitre 4, la page http://127.0.0.1:8080/springapp/priceincrease.htm genere une exception que je n'arrive toujours pas à résoudre.
Voici le contenu de la page:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

Voici la source du JSP en cause (à mon avis):

<%@ include file="/WEB-INF/jsp/include.jsp" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>

<html>
<head>
<title><fmt:message key="title"/></title>
<style>
.error { color: red; }
</style>
</head>
<body>
<h1><fmt:message key="priceincrease.heading"/></h1>
<form:form method="post" commandName="priceIncrease">
<table width="95%" bgcolor="f8f8ff" border="0" cellspacing="0" cellpadding="5">
