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>
  |
