Accéder via JNDI à un EJB via appli standalone

**jecomprendsrien** · 02/07/2012, 16h07

Bonjour,

j'aimerais accéder à une interface remote d'une appli JEE à l'aide de JNDI et d'une appli standalone basique Java.

Quand je déploie mes EJB j'ai ceci dans mes logs Glassfish :

[#|2012-07-02T15:51:18.937+0200|INFO|glassfish3.1.1|javax.enterprise.system.container.ejb.com.sun.ejb.containers|_ThreadID=98;_ThreadName=Thread-2;|Portable JNDI names for EJB helloWorldBean : [java:global/sim_ear/sim_ejb/helloWorldBean!sim.ejb.IHelloWorldBeanLocal, java:global/sim_ear/sim_ejb/helloWorldBean!sim.ejb.IHelloWorldBeanRemote]|#]

Je connais donc les noms JNDI de mon EJB.

J'essaie d'y accéder comme ceci :

Code :

IHelloWorldBeanRemote ejbRemote = null;
 
try {						
	InitialContext ic = new InitialContext();
	ejbRemote = (IHelloWorldBeanRemote)ic.lookup("java:global/sim_ear/sim_ejb/helloWorldBean!sim.ejb.IHelloWorldBeanRemote");
} catch (NamingException e) {
        e.printStackTrace();
}

Dans la FAQ Glassfish (vieillissante il me semble), il est marqué de ne pas utiliser de Properties pour l'instanciation de l'InitialContext, est ce exact...?

Toujours est il que j'ai l'exception suivante :

javax.naming.NamingException: Lookup failed for 'java:global/sim_ear/sim_ejb/helloWorldBean!sim.ejb.IHelloWorldBeanRemote' in SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.url.pkgs=com.sun.enterprise.naming, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl} [Root exception is javax.naming.NamingException: ejb ref resolution error for remote business interfacesim.ejb.IHelloWorldBeanRemote [Root exception is java.rmi.AccessException: CORBA NO_PERMISSION 0 No; nested exception is:

Quelle peut en être la cause svp ?

Merci

Help, personne ?

J'ai essayé toutes sortes d'écritures et de tutos notamment celui ci mais rien à faire...

En détails voici ce que je fais :

j'ai un module EAR, un module EJB (associé à un module EJB client) le tout déployé sur Glassfish v3.1.1)

Mon module EJB contient un EJB HelloWorldBean :

Code :

@Stateless(name="helloWorldBean", mappedName="ejb/helloWorldBean")
public class HelloWorldBean implements IHelloWorldBeanRemote{
 
        @Override
	@PermitAll
	public String testJAAS() {
		return "plop";
	}
 
}

Code :

package sim.ejb;
 
public interface IHelloWorldBeanRemote {
	public String testJAAS();
}

J'ai rajouté un fichier glassfish-ejb-jar.xml dans le META-INF de mon module EJB sans grandes certitudes...

Code :

       </ejb-ref>
   </ejb>
 </enterprise-beans>
</glassfish-ejb-jar>

J'ai packagé et deployé mon ear sous GlassFish sans erreur.

Quand je lance asadmin list-jndi-entries java:global/sim_ear/sim_ejb j'obtiens :

helloWorldBean!sim.ejb.IHelloWorldBeanRemote: javax.naming.Reference

Ensuite, sous Eclipse, j'ai crée un projet "Application Client Project" et codé cela après avoir linké mon module EJB pour avoir les références des interfaces et implémentations EJB :

	}

	 */
	public Main() {
		super();
	}
 
        private void testEJB(){
 
		IHelloWorldBeanRemote ejbRemote = null;
 
		try {			
 
			Context ic = new initialContext();						
 
			ejbRemote = (IHelloWorldBeanRemote)ic.lookup("java:global/sim_ear/sim_ejb/helloWorldBean!sim.ejb.IHelloWorldBeanRemote");
 
		} catch (NamingException e) {
			e.printStackTrace();
		}
 
 
		System.out.println("result : " + (ejbRemote == null));	
 
	}

Mais j'obtiens une exception qui peut varier en fonction de mes tests

interface non trouvée pourtant le nom JNDI est correct...

Quelqu'un a une idée ?

Un grand merci de m'avoir lu déjà

EDIT: dans mon appli cliente, j'ai aussi ajouté les JARs gf-client.jar et appserv-rt.jar

**dev_2007** · 02/07/2012, 23h40

essai de créer toute une classe qui se charge de récupérer le context comme ceci :

Code :

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
 
public class JBossContext {
 
	public static Context getInitialContext() throws NamingException {
 
		Properties prop = new Properties();
		prop.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
		prop.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
		prop.put(Context.PROVIDER_URL,"jnp://localhost:1099");
		return new InitialContext(prop);
 
	}
}

et après tu l'utilise comme suit :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Context ctx=JBossContext.getInitialContext();
InterfaceRemoteEJB interfaceejb =(InterfaceRemoteEJB) ctx.lookup("tonBeanEjb/remote");

j'espère pouvoir répondre à ton besoin.

Salut

Déjà merci de répondre

En fait je suis avec GlassFish et pas JBOSS. J'avais essayé ce genre de chose mais je suis tombé sur la FAQ GlassFish et notamment ceci :

The most common problem developers run into is passing specific JNDI bootstrapping properties to InitialContext(args). Some other vendors require this step but GlassFish does not. Instead, use the no-arg InitialContext() constructor.

alors j'ai arrêté ^^

Merci quand même pour l'aide
