The following is an example of a system service container for internationalizaton:
package com.nexaweb.i18n.utils;
import java.util.Locale;
import java.util.ResourceBundle;
import com.nexaweb.client.ClientSession;
import com.nexaweb.client.macro.Macro;
import com.nexaweb.client.mco.AbstractMco;
import com.nexaweb.client.mco.Container;
import com.nexaweb.session.ClientInfo;
import com.nexaweb.xml.ParserException;
public class I18nServiceRegistrar extends AbstractMco {
private Locale locale;
private ResourceBundle resBundle;
}The following section creates an instance of the service class, itself, and registers it in the SystemContainer. It also sets the locale to the default locale of the client.
public void registerI18nService() {
I18nServiceRegistrar i18nSysService = new I18nServiceRegistrar();
Container sysContainer = getSession().getSystemContainer();
ClientSession clientSession = getSession();
ClientInfo clientInfo = clientSession.getClientInfo();
Locale locale = clientInfo.getLocale();
i18nSysService.setLocale(locale);
sysContainer.put("i18nService", i18nSysService);
}
The following section sets the service locale based on the language and country. It then repaints
the screen based on the new language by calling the macro repaintScreen,
defined in the XAL file.
The language parameter specifies the newly selected language.
The country parameter specifies the newly selected country.
public void setLocale(String language, String country) {
Locale locale = new Locale(language, country);
Container sysContainer = getSession().getSystemContainer();
I18nServiceRegistrar i18nSysService = (I18nServiceRegistrar)
sysContainer.get("i18nService");
i18nSysService.setLocale(locale);
sysContainer.put("i18nService", i18nSysService);
Macro repaintScreenMacro = getSession().getMacroContainer()
.getMacro("repaintScreen");
try {
repaintScreenMacro.execute();
} catch (ParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("Macro parse exception occurred");
}
}
The following section loads the resource bundle for the supplied locale.
The locale parameter specifies the locale.

works with the system service, MCO and properties files shown above:
