WicketMessage: Can't instantiate page using constructor 'public com.mycompany.StartPage()'. An exception has been thrown during construction!

[Sokab]

Hi Everyone! I am new and I want to learn to Wicket. When I create new simple
project with Wicket everything is ok but when I try add EJB class to Wicket
(WebPage) always i have this same error:

"WicketMessage: Can't instantiate page using constructor 'public
com.mycompany.StartPage()'. An exception has been thrown during
construction!"

It is my Wicket class:

import javax.ejb.EJB;
import org.apache.wicket.markup.html.WebPage;
public class StartPage extends WebPage{    
    @EJB
    PersonManagerLocal managerLocal;

    public StartPage() {
        managerLocal.addPerson();
    }    
}
//*******************************************************
EJB class:

@Stateless
public class PersonManager implements PersonManagerLocal{

    @Override
    public void addPerson() {
        System.out.println("HELLO I AM EJB");
    }
//***************************************************************
Interface:
//@Local
public interface PersonManagerLocal {
    public void addPerson();
}
//***************************************************************

//***************************************************************
Wicket initialization class:

public class WicketApplication extends WebApplication{

    @Override
    public Class<? extends WebPage> getHomePage() 
    {
        return StartPage.class;
    }
    
    @Override
    protected void init(){
        super.init();
    }
}

I use: Netbeans 8.2, Wicket 7, EJB3.1, wildfly 10
Maybe someone knows what's wrong? Thank you for any advice.
