ressource not found struts2 spring hibernate

Question

i'm trying to call a result of Struts2 action after getting inputs from a form and putting them in an object to stock in the database my struts.xml is

<action name="showForm" class="com.web.SalarieAction" method="afficherSalarie">
        <result name="success">/pages/form.jsp</result>
</action>

<action name="ajouterSalarie" class="com.web.SalarieAction" method="ajoutSalarie">
    <result name="input">/pages/form.jsp</result> 
    <result name="success">/pages/addBookOk.jsp</result>
</action>

the default action is going well it's giving me the form but it cannot be validated

my class action is

public class SalarieAction extends BaseAction {

    private Salarie salarie ;

    private SalarieService salarieService;

    public String ajoutSalarie() {
        salarieService.addSalarie(salarie);
        System.out.println("a salarieaction - ajoutsalarie method");

        return SUCCESS;
    }

    public Salarie getSalarie() {
        return this.salarie;
    }

    public void setSalarie(Salarie salarie) {
        this.salarie = salarie;
    }

    public SalarieService getSalarieService() {
        return salarieService;
    }

    public void setSalarieService(SalarieService salarieService) {
        this.salarieService = salarieService;
    }

    public String deletSalarie(int id_sal) throws EntityNotFoundException {
        this.salarieService.deleteSalarie(id_sal);
        return SUCCESS;
    }

    public String authentifier(String Salarie, String id_sal,int id_sal_num){

         this.salarieService.authentifier(Salarie,id_sal,id_sal_num);
         return SUCCESS;
    }

    public String afficherSalarie(){
            return SUCCESS;
    }

the class service to stock with it is the following

public class SalarieServiceImpl implements SalarieService {

    private SalarieDao SalarieDao;

    public SalarieDao getSalarieDao() {
        return SalarieDao;
    }

    public void setSalarieDao(SalarieDao salarieDao) {
        SalarieDao = salarieDao;
    }

    public void addSalarie(Salarie salarie) {
        // TODO : probabelement du code permettant de vérifier les régles
        // métiers
        System.out.println("a salarieserviceimpl - addsalarie");
        SalarieDao.create(salarie);

        //TODO : eventuellement du code metier à ajouter
    }

    public void deleteSalarie(int id_sal) throws EntityNotFoundException {
        // TODO : probabelement du code permettant de vérifier les régles
        // métiers

        SalarieDao.delete(id_sal);

        //TODO : eventuellement du code metier à ajouter
    }

    public Salarie  authentifier(String Salarie, String id_sal,int id_sal_num) {
        Salarie salarie= SalarieDao.getEntityByColumn(Salarie, id_sal, id_sal_num);
        return  salarie;
    }

the dao class is

public class SalarieDaoImpl extends GenericDaoImpl<Salarie, Integer> implements SalarieDao {

    public SalarieDaoImpl() {
        // car on travail sur des objets de la classe metier, il y a des méthodes
        // hibernate qui auront besoin de cette information cf. le code de
        // generic dao
        super(Salarie.class);
    }

    public Salarie getEntityByColumn(String Salarie, String id_sal,int id_sal_num) {
        // Une requete HQL simple pour faire la selection
        String HqlQuery = "from " + Salarie + " where " + id_sal
                + " = ?";

        List l = getHibernateTemplate().find(HqlQuery, id_sal_num);
        if (l == null || l.size() == 0)
            throw new ObjectRetrievalFailureException(Salarie, null);
        return (com.bo.Salarie) l.get(0);
    }

my form in jsp is

    `<%@taglib uri="/struts-tags" prefix="s"%>
    <%@ taglib uri="http://displaytag.sf.net" prefix="d"%>
    <%@ taglib prefix="sj" uri="/struts-jquery-tags" %>


    <jsp:include page="inc/header.jsp" flush="true" />

    <jsp:include page="inc/menu.jsp" flush="true" />
