How to deploy a Java EE simple application

I'm trying to run this simple and small application but I don't understand which is the problem and consequently how to fix it.
Here it is the code. It is very simple. One bean invoked by a client application in order to print out in the client terminal the well-known message Hello World. I have created the application by using Intellij Idea 13.0.3 IDE with Server GlassFish 4.0.0, Java JDK 8.0. May you explain me step-by-step what I should do to run this application in the ide?

package myejb;

import javax.ejb.Remote;

@Remote
public interface Hello
{
    public String sayHello(String name);
}

package myejb;

import javax.ejb.Remote;
import javax.ejb.Stateless;


@Stateless(name = "HelloEJB")
@Remote({Hello.class})
public class HelloBean implements Hello
{
    public HelloBean()
    {

    }

    @Override
    public String sayHello(String name)
    {
        return "Hello, " + name + "!";
    }
}

and the Client application

package myejbclient;

import javax.ejb.EJB;
import myejb.Hello;

public class HelloClient
{
    @EJB(lookup = "HelloEJB")
    private static Hello hello;

    public HelloClient()
    {

    }

    public static void main(String[] args)
    {
        HelloClient client = new HelloClient();
        client.doConversation();
    }

    public void doConversation()
    {
        System.out.println(hello.sayHello("World"));
    }
}

I execute glassfish to deploy the application. it is deployed correctly but when I run the client application I get this error message:

Exception in thread "main" java.lang.NullPointerException
