Bonsoir ,

SVP j'ai un petit soucis avec un simple exemple d'EJB3

Mon EJB

/*interface*/

package com.et;

import javax.ejb.Local;
import javax.ejb.Remote;

@Remote

public interface PremierEJB3 {
	public String ditBonjour(String aQui);
}

Le bean

package com.et;


import javax.ejb.Stateless;

@Stateless
public class PremierEJB3Bean implements PremierEJB3{

	@Override
	public String ditBonjour(String aQui) {
		System.out.println("Bonjour" + aQui);
		return null;
	}

}

Le client

package com.et;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class ClientPremierEJB3 {

   public static void main(String[] args) {
      try {
         Context context = new InitialContext();
         PremierEJB3 beanRemote = (PremierEJB3)
         context.lookup("com.et.PremierEJB3Bean/remote");
         System.out.println(beanRemote.ditBonjour("ClientPremierEJB3"));
      } catch (NamingException e) {
         e.printStackTrace();
      }
   }
}

Et voila le message d'erreur :

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial
	at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)
	at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288)
	at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:325)
	at javax.naming.InitialContext.lookup(InitialContext.java:392)
	at com.et.ClientPremierEJB3.main(ClientPremierEJB3.java:14)

La solution : Modification au niveau de client

package com.et;

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class ClientPremierEJB3 {

   public static void main(String[] args) {
	   Properties props = new Properties();     
      try {
    	  
    	  
    	        
          props.setProperty(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
           props.setProperty(Context.PROVIDER_URL, "localhost:1099");
           props.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); 
	    	  
	    	  //System.out.println("***************************la");
	   InitialContext context = new InitialContext(props);
	   System.out.println("2");
         PremierEJB3 beanRemote = (PremierEJB3)
         context.lookup("PremierEJB3Bean/remote");
         System.out.println("3");
         System.out.println(beanRemote.ditBonjour("Amine"));
      } catch (NamingException e) {
         e.printStackTrace();
      }
   }
}
