Accès JNDI à un EJB

**olivier57b** · 01/03/2009, 02h26

salut,

voici le problème : je n'arrive pas à appeler via JNDI un EJB.

j'ai créé un projet EAR qui contient un projet EJB, un projet EJBClient et un projet JPA, tous les 3 peuplés avec des EJB, une classe avec "main", et des entities.

voici le code d'un EJB:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

package ejb.customer;
 
import(...)
 
@Stateless
public class CustomerBean implements CustomerLocal, CustomerRemote {
 
	@PersistenceContext(unitName="petstorePU")
	private EntityManager em;
 
 
	public Customer authenticate(String login, String password) {
		if (login==null || login.equals(""))
			throw new ValidationException("Invalid login");
        (...)

voici le code de la classe cliente:

package source_client;
 
import javax.naming.Context;
import javax.naming.InitialContext;
 
import source.customer.Customer;
 
 
public class client1 {
 
	/**
         * @param args
         */
	public static void main(String[] args) {
 
		try {
			Context ctx=new InitialContext();
			ejb.customer.CustomerRemote rem=(ejb.customer.CustomerRemote) ctx.lookup("ejb.customer.CustomerBean/remote");
			rem.createCustomer(new Customer(1L,"jambon","rose","jean","bonrause","0018654118","jeanroi@gmail.com",new java.util.Date(1978,02,10),19,null),new source.Address(1,"4 rue des roses","","METZ","Moselle","57000","FRANCE"));
 
 
			System.out.println ("--- Hello, clients ---");
			for (source.customer.Customer client : rem.findCustomers()) {
				System.out.println ("client : "+client);
			}
 
		} catch (Exception e) {
			e.printStackTrace();
		}
 
 
 
 
 
	}
 
}

et voici le code de jndi.properties, que j'ai placé dans le répertoire des sources du client:

Code :

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099

j'ai aussi ajouté un fichier persistence.xml dans le répertoire META-INF du projet EJB:

j'oubliais : voici le message d'erreur : "javax.naming.NameNotFoundException: CustomerBean not bound"

**olivier57b** · 01/03/2009, 03h04

j'ai maintenant les EJB qui sont déployés via JNDI : voici un extrait de la page JNDIView sur la page web de JBOSS :

mais je n'arrive toujours pas à m'y connecter avec le classe client : regardez la photo, on y voit que l'EJB est déployé et l'appel refusé.

Salut olivier57b, aurais-tu résolu ton problème...?

Ca m'intéresse !

Je suis la même voie que toi, à savoir que je me mets à JEE en suivant le livre d'A. Goncalves.

J'en suis encore à essayer de comprendre comment reprendre l'arborescence de l'application dans un Enterprise Application Project sous Eclipse...
