bn pour le code de la servlet est le suit

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		HttpSession masess=request.getSession(true);
		Long  idsite=Long.parseLong(request.getParameter("idsite")) ;
        Organisationbean modl = new Organisationbean();
	    modl=orgAffich.AfficheOrg(idsite);
		masess.setAttribute("Modelorg", modl);
		response.sendRedirect("organisation.jsp");
		
	
	}

et bien sur laclasse d'implementation dont j'ai declarée ma requete :

try {
			rq = (PreparedStatement) connect.prepareStatement("select idorg,description1, email , site2, orgmere , solde from orgaStage O , sitStage S where O.site2=S.idsite  order by idorg ");
			ResultSet rs = rq.executeQuery();
			while (rs.next()) {

				Organisationbean  p = new Organisationbean();
				
				
				p.setIdorg(rs.getLong("idorg"));
				p.setDescription1(rs.getString("description1"));
				p.setEmail(rs.getString("email"));
			    p.setSite2(rs.getInt("site2"));
				p.setOrgmere(rs.getInt("orgmere"));
				p.setSolde(rs.getDouble("solde"));
				
				return(p);
		}
