Premier appli - pb avec appel Local
Bonsoir,
J'ai repris un tutoriel de débutant pour faire ma premier mini appli en EJB3. J'ai ces classes là :
Code:

| package com.business;
import javax.ejb.Local;
import javax.ejb.Remote;
@Remote
public interface PremierEJB3 {
public String ditBonjour(String aQui);
} |
Code:

| package com.business;
import javax.ejb.EJB;
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Stateless
public class PremierEJB3Bean implements PremierEJB3 {
@EJB private PremierEJB3 premierEJBLocal;
public String ditBonjour(String aQui) {
return "Bonjour " + aQui + " !!!";
}
} |
Code:

| package com.jp;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.business.PremierEJB3;
public class ClientPremierEJB3 {
public static void main(String[] args) {
try {
Context context = new InitialContext();
PremierEJB3 beanRemote = (PremierEJB3)context.lookup("PremierEJB3Bean/Remote");
System.out.println(beanRemote.ditBonjour("ClientPremierEJB3"));
} catch (NamingException e) {
e.printStackTrace();
}
}
} |
En Remote, ça marche bien.
Mais dès que j'annote l'interface par @Local, ça ne fonctionne pas.
J'ai essayé d'appeler mon session bean comme ça :
Code:
PremierEJB3 beanRemote = (PremierEJB3)context.lookup("PremierEJB3Bean/Local");
erreur :

Comment appeler un session bean en Local?
Merci pour vos réponses.
