OK thank you :) , actually i resolved the problem by creating an extension
of the service in wish i override the function list like this
> public List<Societe> list() throws ServiceException {
> List<Societe> list = new ArrayList<Societe>();
> List<Societe> societes=new ArrayList<Societe>();
> log.debug("debut de la recherche des objets Societe ");
> try {
> list = getSocieteDao().list();
>
>
> if(list!=null){
> for(Societe societe :list){
> Societe s=new Societe();
> s.setNomsociete(societe.getNomsociete());
> societes.add(s);
> }
> }
> log.debug("fin de recherche des objets Societe ");
> } catch (Exception re) {
> log.error("erreur de recherche ", re);
> throw new ServiceException(
> "error lors de la recherche de l'objet Societe : "
> + re.toString());
> }
> return societes;
> }
>
>
but i will use dto , i think it is better
thank you again
