               </form:form> 
         </div> 
         </div> 

c'est la classe modèle

public class Offer implements java.io.Serializable { 

    private long offerid; 
    private Merchant merchant; 
    private MerchantUser merchantUserByAddedByRef; 
    private MerchantUser merchantUserByLastModifiedByRef; 
    private String issueDateTime; 
    private BigDecimal pointsAllocated; 
    private String expiryDate; 
    private String offerHeading; 
    @NotEmpty 
    private String offerSubheading; 
    @NotEmpty 
    private String offerDescription; 
    private String offerFilterTypes; 
    private String videoUrl; 

ceci est le fichier message.property

NotEmpty.Offer.offerSubheading = Heading field can't be Empty! 
NotEmpty.Offer.offerDescription = Heading field can't be Empty! 

ici dans la page jsp, après cliquant sur le bouton apparaît form.when pertinent après avoir fait la validation si leur a une erreur, il rediriger vers la page jsp alors ne devrait pas avoir que forme here.because de cette forme apparaîtra seulement après cliquage .donc que msg d'erreur ne peut pas montré

images suivantes sont que .jsp vue .jsp page view before press single image buttonafter click that single image button

Answer 1

finalement je l'ai fait mon travail le problème était @ModelAttribute ("offres") ---> offres et commandName = "De fer "ne sont pas correspondre les uns aux autres :)
