Como consumir um web service?

package br.com.servico;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

@WebService
public interface ClienteServicoWS {

	
	@WebMethod
	@WebResult(name="Codigo")
	public void criar(@WebParam(name="Nome") String nome, 
						 @WebParam(name="Sobrenome") String sobrenome);
}

package br.com.servico;

import javax.ejb.Stateless;
import javax.jws.WebService;

@Stateless
@WebService(name="ClienteWS")
public class ClienteServicoEJB implements ClienteServicoWS{

    public ClienteServicoEJB() {
        
    }

	@Override
	public void criar(String nome, String sobrenome) {
		// TODO Auto-generated method stub
		System.out.println("Nome: " + nome);
		System.out.println("Sobrenome: " + sobrenome);
	}

}
