probélme de GetFeature lors de plusieurs Layer ou un gourpe layer
bonjour ,
cher amies j'ai besoin de votre aide j’arrive pas a récupérer des informations sur ma couche grâce a la fonction OpenLayers.Control.GetFeature quand j'ai 2 couche mais pour une seul couche ça marche bien voici le code utilisé
Code:
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
