Hi, I'm a new one working with J2EE. I'm developing an application and I need to access the EJBs from my client (a Java application).

   This is the code of my client (a test one):

 

package clients;

import java.util.Properties;

import javax.rmi.PortableRemoteObject; 

import javax.naming.*;

class Client

 {

    public static void main(String[] args)

    {

       Properties env = new Properties();

       
// Define properties and JNDI names lookup location.

       env.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");

       env.setProperty("java.naming.provider.url",  "localhost:1099");

       env.setProperty("java.naming.factory.url.pkgs",  "org.jboss.naming");

       
try

       {

          // Bring the name context

          InitialContext jndiContext = new InitialContext(env);

          System.out.println("Contexto Disponible");

          
// Bring the referente to the EJB

          Object ref  = 
jndiContext.lookup("Calculo");

          System.out.println("Se encontró Referencia del EJB!");

          // Bring the referente to the "Home Interface "

          InteresesHome home = (InteresesHome) 

          PortableRemoteObject.narrow (ref, InteresesHome.class
);

          // Create an object from the "Home Interface"

          Intereses interes = 
home.create();

          // Call the function 

          System.out.println
("Interés de 10,000 Capital, a tasa 10%, bajo 2 plazos anuales:");

          
System.out.println(interes.calcularInteres(10000, 0.10, 2));

       }

       catch(Exception e)

       {

          System.out.println(
e.toString());

       }

    }

 }

When I execute this, there is an error. It says :   javax.naming.NoInitialContextException : Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException : org.jnp.interfaces.NamingContextFactory]

Would some of you be so kind to help me fixing that? What sould I do?
