Deleting complex object in Java list (for implementation on WSDL)

Question

I am following those three tutorials and I have completed it with success.
( http://oracleadfhowto.blogspot.in/2013/03/create-simple-web-service-using-oracle.html )
( http://oracleadfhowto.blogspot.in/2013/03/consuming-web-service-using-web-service.html )
( http://oracleadfmobile.blogspot.in/2013/03/consuming-soap-web-service-in-adf.html )
But then, as author haven't implemented removeCountries method I tried to create it.
What I did initially was to just add to class Countries this method:
  public boolean removeCountry(Country country) {
  return countries.remove(country);
But although compiler wasn't complaining it didn't work. Actually it worked last night (before reboot) but not today.
Must be some SOAP iterator/bindig thing or whatever. Or I thought  that it worked but in fact it didn't.
Here are original classes:
public class Country {
    String CountryId;
    String CountryName;
    public Country() {
        super();
    public Country( String id, String name ) {
        super();
        this.CountryId = id;
        this.CountryName = name;
    public void setCountryId(String CountryId) {
        this.CountryId = CountryId;
    public String getCountryId() {
        return CountryId;
    public void setCountryName(String CountryName) {
        this.CountryName = CountryName;
    public String getCountryName() {
        return CountryName;
public class Countries {   
    List<Country> countries = new ArrayList<Country>();
    public Countries() {
        super();
    public void setCountries(List<Country> countries) {
        this.countries = countries;
    public List<Country> getCountries() {
        if ( countries.size() == 0 ) {
            countries.add( new Country("IT","ITALY"));
            countries.add( new Country("IN","INDIA"));
            countries.add( new Country("US","UNITED STATES"));
        return countries;
    public boolean addCountry( Country country ) {
        return countries.add( country );
  // I added this
  public boolean removeCountry( Country country ) {
        return countries.remove( country );
Then I decided to write (for a start) just plain Java classes and now it looks like below shown code.
It works in IDE, not yet implemented on weblogic server. I hope it would work.
package client;
public class Country {
  String CountryId;
  String CountryName;
  public Country() {
  super();
  public Country(String id, String name) {
  super();
  this.CountryId = id;
  this.CountryName = name;
  public void setCountryId(String CountryId) {
  this.CountryId = CountryId;
  public String getCountryId() {
  return CountryId;
  public void setCountryName(String CountryName) {
  this.CountryName = CountryName;
  public String getCountryName() {
  return CountryName;
package client;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class Countries {
  List<Country> countries = new ArrayList<Country>();
  public Countries() {
  super();
  public void setCountries(List<Country> countries) {
  this.countries = countries;
  public List<Country> getCountries() {
  if (countries.size() == 0) {
  countries.add(new Country("IT", "ITALY"));
  countries.add(new Country("IN", "INDIA"));
  countries.add(new Country("US", "UNITED STATES"));
  return countries;
  public boolean addCountry(Country country) {
  return countries.add(country);
  // This left unused
  public boolean removeCountry(Country country) {
  return countries.remove(country);
  // I added this - what would be more elegant or smarter way to do this?
  public void removeCountry(String CountryId, String countryName) {
  Iterator<Country> iterator = countries.iterator();
  while (iterator.hasNext()) {
  Country value = iterator.next();
  if (CountryId.equals(value.CountryId) || countryName.equals(value.CountryName)) {
  iterator.remove();
  break;
This class is just for test it won't go on server (JDeveloper integrated web logic server)
package client;
public class UserInterface {
  public static void main(String[] args) {
  String CountryId = "";
  String CountryName = "";
  CountryName = "ENGLAND";
  Countries co = new Countries();
  co.getCountries();
  for (int i = 0; i < co.countries.size(); i++) {
  System.out.print(co.getCountries().get(i).getCountryId());
  System.out.print(" - ");
  System.out.println(co.getCountries().get(i).getCountryName());
  System.out.println("-------------------------");
  // Add some countries
  co.countries.add(new Country("DE", "GERMANY"));
  co.countries.add(new Country("EN", "ENGLAND"));
  for (int i = 0; i < co.countries.size(); i++) {
  System.out.print(co.getCountries().get(i).getCountryId());
  System.out.print(" - ");
  System.out.println(co.getCountries().get(i).getCountryName());
  System.out.println("-------------------------");
  // Remove some countries, this works but can't use this (index)
  // co.countries.remove(0); <--- there should be some index instead of 0
  // I need to set properties
  CountryId = "DE";
  CountryName = "";
  // Then remove country
  co.removeCountry(CountryId, CountryName);
  CountryId = "";
  CountryName = "ENGLAND";
  // Then remove country
  co.removeCountry(CountryId, CountryName);
  // Is there any way to remove object directly? Parameters should be set by web service iterator.
  // co.countries.remove(o);
  // co.removeCountry(country)
  for (int i = 0; i < co.countries.size(); i++) {
  System.out.print(co.getCountries().get(i).getCountryId());
  System.out.print(" - ");
  System.out.println(co.getCountries().get(i).getCountryName());
I would like to avoid my own iterator as JDeveloper can generate automatically iterators for webservices, but if I can't get it that way, what would be better way to write above mentioned iterator in removeCountry method?
Is there any way to remove object directly with something like this:
co.countries.remove(o);
co.removeCountry(country)
using method
  // This left unused
  public boolean removeCountry(Country country) {
  return countries.remove(country);
from class Countries?
Parameters should be set by web service iterator.
