Comment résoudre javax.de nommage.NameNotFoundException à ce code

Je fais un Ejb projet de netbean 7.3 avec jboss-7.1.1 Final

Dans le module Ejb j'ai ces:

LibrarySessionBeanRemote.java

package com.tutorialspoint.stateless;

import java.util.List;
import javax.ejb.Remote;

@Remote
public interface LibrarySessionBeanRemote {
void addBook(String bookName);
List getBooks(); 
}

LibrarySessionBean.java

package com.tutorialspoint.stateless;

import java.util.ArrayList;
import java.util.List;
import javax.ejb.Remote;
import javax.ejb.Stateless;


@Stateless
@Remote(LibrarySessionBeanRemote.class)
public class LibrarySessionBean implements LibrarySessionBeanRemote {

List<String> bookSelf;    

public LibrarySessionBean() {
this.bookSelf = new ArrayList<String>();
}

@Override
public void addBook(String bookName) {
bookSelf.add(bookName);
}

@Override
public List getBooks() {
return bookSelf;
}
}

et je fais un client avec l'application java type de projet

package client;
import com.tutorialspoint.stateless.LibrarySessionBeanRemote;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.List;

import javax.naming.NamingException;
public class EJBTester {

props.put(Context.INITIAL_CONTEXT_FACTORY,   org.jboss.naming.remote.client.InitialContextFactory.class.getName());
try {
ctx = new InitialContext(props);
} catch (NamingException ex) {
ex.printStackTrace();
}
brConsoleReader =
new BufferedReader(new InputStreamReader(System.in));
}
public static void main(String[] args) {
EJBTester ejbTester = new EJBTester();
ejbTester.testStatelessEjb();
}
private void showGUI() {
System.out.println("**********************");
System.out.println("Welcome to Book Store");
System.out.println("**********************");
System.out.print("Options \n1. Add Book\n2. Exit \nEnter Choice: ");
}
private void testStatelessEjb() {
try {
int choice = 1;
LibrarySessionBeanRemote libraryBean =
(LibrarySessionBeanRemote) ctx.lookup("LibrarySessionBean/remote");
while (choice != 2) {
String bookName;
showGUI();
String strChoice = brConsoleReader.readLine();
choice = Integer.parseInt(strChoice);
if (choice == 1) {
System.out.print("Enter book name: ");
bookName = brConsoleReader.readLine();
libraryBean.addBook(bookName);
} else if (choice == 2) {
break;
}
}
List<String> booksList = libraryBean.getBooks();
System.out.println("Book(s) entered so far: " + booksList.size());
for (int i = 0; i < booksList.size(); ++i) {
System.out.println((i + 1) + ". " + booksList.get(i));
}
LibrarySessionBeanRemote libraryBean1 =
(LibrarySessionBeanRemote) ctx.lookup("LibrarySessionBean/remote");
List<String> booksList1 = libraryBean1.getBooks();
System.out.println(
"***Using second lookup to get library stateless object***");
System.out.println(

for (int i = 0; i < booksList1.size(); ++i) {
System.out.println((i + 1) + ". " + booksList1.get(i));
}
} catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
} finally {
try {
if (brConsoleReader != null) {
brConsoleReader.close();
}
} catch (IOException ex) {
System.out.println(ex.getMessage());
}
}
}
}
