      I changed my code to be like that:
       @SelectItems(label="label")
       private List<Codes> cLang;
      
       @Factory("cLang")
       public void getLanguages()
       {
       List resultList = em.createQuery("select c from Codes c where c.table = :table")
       .setParameter("table","languages")
       .getResultList();
       this.cLang = resultList;
      
       }

      and my jsfto :
       <h:selectOneMenu converter="org.jboss.seam.EntityConverter">
       <f:selectItems value="#{cLang}" />
       </h:selectOneMenu>
