JNDI "Cannot instantiate class: org.jboss.naming.remote.client.InitialContextFactory"

I'm using JBoss Server for EJB And I need JNDI in console app to get reference of session bean,
console app code looks like this

import java.util.Properties;

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


public class Program {

public static void main(String[] args) throws NamingException {
// TODO Auto-generated method stub
Properties pr = new Properties();
pr.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
pr.put(InitialContext.PROVIDER_URL,"remote://localhost:4447");
InitialContext ic = new InitialContext(pr);

}

}


when I run the application I get exception

Exception in thread "main" javax.naming.NoInitialContextException: Cannot instantiate class: org.jboss.naming.remote.client.InitialContextFactory [Root exception is java.lang.ClassNotFoundException: org.jboss.naming.remote.client.InitialContextFactory]

Answer

You can use following context to connect. I have tried and tested to set up this.

import java.util.Properties;
import javax.naming.Context;
import javax.naming.NamingException;


public class Program {

    public static void main(String[] args) throws NamingException {
      Properties jndiProps = new Properties();
    jndiProps.put(Context.INITIAL_CONTEXT_FACTORY,         
    "org.jboss.naming.remote.client.InitialContextFactory");
    jndiProps.put(Context.PROVIDER_URL,"remote://localhost:4447");
    jndiProps.put(Context.SECURITY_PRINCIPAL, "testuser");
    jndiProps.put(Context.SECURITY_CREDENTIALS, "testpassword");
    jndiProps.put("jboss.naming.client.ejb.context", true);
    Context ctx = new InitialContext(jndiProps);
    }

}

Then i got this error

JBREM000200: Remote connection failed: javax.security.sasl.SaslException: 
Authentication failed: all available authentication mechanisms failed - Could 
not register a EJB receiver for connection to remote://localhost:4447  
java.lang.RuntimeException: javax.security.sasl.SaslException: Authentication 
failed: all available authentication mechanisms failed.

Then i added the user using add-user.sh.

Successful Handshake message came.
