Struts - Cannot find bean in any scope

Question

I'm using eclipse to implement with the native Struts and hybernate support an application to display a series of links in a page. I'm getting the error:

javax.servlet.jsp.JspException: Cannot find bean: "ListeActeur" in scope: "session"

I've checked a lot of sites and forums, and nothing seems to fix this.

My struts-config:

<struts-config>
<form-beans type="org.apache.struts.action.ActionFormBean">
  <form-bean name="ListeActeur" type="mesForms.strust.ListeActeur"/>
  <form-bean name="vérifCritère" type="mesForms.strust.vérifCritère"/>
</form-beans>
<action-mapping>
    </action>   
    <action path="/Liste" 
    parameter="/vue/Invitation.jsp"
    name="ListeActeur     scope="request       validate="false"
                     type="mesAction.struts.ListeActeurAction">  
    <forward name="s" path="/vue/NewFile.jsp" redirect="false" /> 
    </action>
</action-mappings>
</struts-config>

ListeActeurAction:

    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest req, HttpServletResponse res) throws Exception {
        System.out.println("Action");

        ListeActeur ListeActeur= (ListeActeur) form;
        String query = "select * from Acteur " ;

        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
         Iterator results = session.createSQLQuery(query).list().iterator();
         List <Acteur> lis = new ArrayList<Acteur>();
         while((results.hasNext()))
         {
             Acteur gg =new Acteur();
            Object[] row = (Object[]) results.next();
            gg.setActeurId((Integer)row[0]);
            gg.setNomActeur((String)row[2]);

             lis.add(gg);
         }
         req.getSession(true).setAttribute("lis", lis);
         session.getTransaction().commit();
         HibernateUtil.getSessionFactory().close();             
        ListeActeur.setLis( lis);
        req.setAttribute("formu", ListeActeur.getLis());

        return mapping.findForward("s");
        }
}

ListeActeur:

public class ListeActeur extends ActionForm {

private  List <Acteur> lis=null;

public List <Acteur> getLis(){
    return lis;}
public void setLis(List <Acteur> lis){this.lis=lis;}
public void reset(ActionMapping mapping, HttpServletRequest request) { 

    lis = new ArrayList<Acteur>();  
}

I really dont know what to do. Im a newbie in Struts.Thanks in advance!

You have

<action path="/Liste" scope="request" .../>

and

<logic:iterate ... scope="session" >

no wonder you get this exception. If you configure Struts to store the form bean in the request, don't try to fetch it from the session in your JSP.

yes thank you ,i have an other problem : jsp page always displays an empty list even though my list is not empty please help me – toutou May 27 '12 at 18:08
You enclosed the logic:iterate inside a logic:empty tag. This means that you iterate only if the list is empty. – JB Nizet May 27 '12 at 18:15
I remove the tag ligic: empty, but the same problem it displays a blank page even table it does not display,Here is the code of page
