hello every one
i wrote a simple cart session bean(Cart.class,CartHome.class,CartBean.class),packaged them into a jar file,and deployed it in the jboss2.4.4,now i want to test it.

according the tutorial in this website,i wrote a "CartTestClient.class" and a "jndi.properties"file,the "jndi.properties" as follow:

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


i set the classpath ENVIRONMENT VARIABLE to point to file:

..........F:\myjava\jboss\client\jndi.properties

go to the directory that contain the "CartTestClient.class",type:

java com.mansion.ejb.CartTestClient

the output is:

F:\myjava\jboss\client>java com.mansion.ejb.CartTestClient
javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interf
aces.NamingContextFactory. Root exception is java.lang.ClassNotFoundException:

at com.mansion.ejb.CartTestClient.main(CartTestClient.java:37)


my "jndi.properties" and "CartTestClient.class" are within the same directory.

my "CartTestClient.java" as follow:


package com.mansion.ejb;

import javax.naming.*;
import javax.rmi.PortableRemoteObject;
import java.util.*;
public class CartTestClient {
private CartHome cartHome = null;

public static void main(String[] args) {
try{
Context initial=new InitialContext();
Object objref=initial.lookup("tt");
CartHome home=(CartHome)PortableRemoteObject.narrow(objref,CartHome.class);
Cart shoppingCart=home.create("Duke","123");

...................
...................
...................


}catch(Exception e){
e.printStackTrace();
}
}
}

why? which one is wrong?"jndi.properties" or "CartTestClient.java"?


thanks for any helps!
