package marouene;
 
import java.io.IOException;
import gcp.httpeasy.Http;
import gcp.httpeasy.Request;
 
public class HttpClient {
 
	/**
         * @param args
         * @throws IOException 
         * 
         */
 
 
 
	public static double debithttp (String adresse) {
 
		Request request = Http.get(adresse);
 
		long start = System.currentTimeMillis();
 
                //appel au serveur
		byte[] response = request.asBytes();
 
		long fin = System.currentTimeMillis();
 
	return  (double)response.length / (fin - start);
 
	}
 
}

une fois ce code executé ici

Visiblement, la librairie httpclient (je suppose que c'est ça), n'était pas accessible. T'es sûr que t'as bien mis le jar au bon endroit?

[marouene_]

oui j'ai ajouté tous les jar :
Build path ---> Configure Build path--->Add external jar....
ke probleme de Http semble resolu

mais celui de Mysql pas encore ,
