I have deployed it through Jboss wildfly 8.2.0 Final 

Now i wnat to acces this EJB or cardValidator()

public static void main(String[] args)

  {

  try {

  boolean status;

  Properties props=new Properties();

  System.out.println("properties are initialising");

  props.setProperty("java.naming.factory.initial", "org.jboss.naming.remote.client.InitialContextFactory");

  System.out.println("property 1 initilised");

  props.setProperty("java.naming.provider.url","remote://localhost:4447");

  System.out.println("property 2 initilised");

  //props.put(Context.SECURITY_PRINCIPAL, "jerry");

  //System.out.println("property 3 initilised");

  //props.put(Context.SECURITY_CREDENTIALS, "jerry@tom1");

  //System.out.println("property 4 initilised");

  InitialContext context=new InitialContext(props);

  System.out.println("context initilised");

  Object object=context.lookup("Cards");

  System.out.println("cards founds");

  CardValidatorHome home=(CardValidatorHome)PortableRemoteObject.narrow(object, CardValidatorHome.class);

  System.out.println("CardValidatorHome");

  CardValidator remote=home.create();

  System.out.println("CardValidatorRemote");

  status = remote.validateCard(12345,1500);

  if(status)

  System.out.println("Card Accepted");

  else

  System.out.println("Card Declined");

  }

  catch (ClassCastException e)

  {

  // TODO Auto-generated catch block

  e.printStackTrace();

  }

  catch (RemoteException e)

  {

  // TODO Auto-generated catch block

  e.printStackTrace();

  }

  catch (NamingException e)

  {

  // TODO Auto-generated catch block

  e.printStackTrace();

  }

  }

------------>through this i m accessing it when i try to run it it gives exception as follows
