<body><h3>Formulaire Ajouter un membre </h3>
<!-- ?????????????????? -->
<form:form commandName ="commandAjout">
<!-- ?????????????????? -->
<table>
<tr>
<td>Nouveau Membre</ td>
<td><form:input path ="nouveauMembre" /></td>
<%-- Show errors for name field --%>
<td><form:errors path="nouveauMembre" /></td >
</tr>
<tr>
<td colspan="3"><input type="submit" value="Envoyer" /></td>
</tr>
</table>
</form:form>
</body ></html> |
A la page 6-4 on dit:"Il faut indiquer la vue qui contiendra le formulaire
Il faut déclarer le nom et la classe de l’objet Command
qui contiendra les données du formulaire"
Dans mon application j'utilise mon objet Participant, rien de particulier nom, prenom, adresse ect ...
Mon erreur est la suivante:
