Try to use:

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService(serviceName="Hi")
public class HelloWS {
        @WebMethod
        public String sayHello(String name) {
                return "Hello " + name;
        }
}

instead of code from article.

I don't know why but I just need to change serviceName and everything run well.
On my computer, if I use code from the article, an error about two servlets have the same url pattern:

java.lang.IllegalStateException: Servlet [HelloServiceService] and Servlet [HelloService] have the same url pattern: [/HelloServiceService]at org.glassfish.apf.AnnotationInfo_at_aeaea6
