1.First.java

package demo.hw.server;

import javax.jws.*;

@WebService
public interface First {
public Person sayHi(@WebParam(name = "name")String name);
}

2.FirstImpl.java

package demo.hw.server;

import javax.jws.*;

@WebService(endpointInterface = "demo.hw.server.First",
serviceName = "HelloWorld")
public class FirstImpl implements First {

public Person sayHi(String name) {

          Person person = new Person();
          person.name = name;
          person.sex = "man";

          return person;
}

}

3.Person.java

package demo.hw.server;

public class Person {
public String name;
public String sex;
}

package demo.hw.server;

5.Client.java

package demo.hw.server;

  factory.setServiceClass(First.class);
  factory.setAddress("http://localhost:9000/helloWorld");
  First client = (First) factory.create();

  Person reply = client.sayHi("HI");
  System.out.println("Server said: " + reply);
  System.exit(0);
}
}
