При запуске программы , вылазит ошибка :

Exception in thread "main" javax.naming.NoInitialContextException: Cannot instantiate class: java.naming.factory.initial [Root exception is java.lang.ClassNotFoundException: java.naming.factory.initial]

Вот код программы :

import javax.naming.*;
import java.io.File;
import java.util.Properties;
public class JndiLesson {
    public static void main(String[] args) throws NamingException {
        String name = "txt.txt";

        Properties props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
        props.put(Context.PROVIDER_URL, "file:///");
        Context initialContext = new InitialContext(props);
        //File obj = (File) initialContext.lookup(name);
        //System.out.println(obj.getName());
        // if (name.equals(""))
        //    System.out.println("Looked up the initial context");
        //else
        //    System.out.println(name + " is bound to: " + obj);
        //NamingEnumeration bindings = initialContext.listBindings("/src/");
        //  while (bindings.hasMore()) {
        //     Binding bd = (Binding) bindings.next();
        // System.out.println(bd.getName() + ": " + bd.getObject());
        //  }
    }
}

Почему возникла данная ошибка и как её решить? P.S. Использую java 9
