Hi there,
I'm trying to call an session Bean (EJB3 - jboss 4.0.5) methods from a simple client. But it returns me the following error:
Caught an unexpected exception: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory
in the classpath:
jboss-j2ee.jar
Cart - dist/Cart.jar (the ejb module)
jdk 1.5
-default package
|- jndi.properties
|
|- cartClient
|-Main.java
the jndi.properties
### JBossNS client properties for connection from the localhost

java.naming.provider.url=jnp://localhost:1099/
# The jnp protocol socket factory class

and the Main.java
public class Main {
/** Creates a new instance of Main */
public Main() {
}
/**

public static void main(String[] args) {
// TODO code application logic here
try{
Context ctx = new InitialContext();
Object objRef = ctx.lookup("ejb/CartBean");
CartRemoteHome home =
(CartRemoteHome)PortableRemoteObject.narrow(objRef, CartRemoteHome.class);
CartRemote shoppingCart = home.create("Duke DeEarl", "123");
shoppingCart.addBook("The Martian Chronicles");
shoppingCart.addBook("2001 A Space Odyssey");
shoppingCart.addBook("The Left Hand of Darkness");
Vector bookList = new Vector();
bookList = shoppingCart.getContents();
Enumeration enumer = bookList.elements();
while (enumer.hasMoreElements()) {
String title = (String) enumer.nextElement();
System.out.println(title);
}
shoppingCart.removeBook("Alice in Wonderland");
shoppingCart.remove();
System.exit(0);
}catch(BookException ex){
System.err.println("Caught a BookException " + ex.getMessage());
System.exit(0);
}catch(Exception ex){
System.err.println("Caught an unexpected exception: " + ex.getMessage());
System.exit(1);
}
}
}Any help? Thanks in advance.
