How to implement custom internationalization with gwt?

I want to make custom internationalization for my gwt app. What does this means? Imagine that开发者_StackOverflow中文版 my app must be internationalized for men and women. (id=men, id=women). is it possible to make two different .properties files like MyAppMessages_men_en.properties MyAppMessages_women_en.properties

MyAppMessages_men_fr.properties MyAppMessages_men_fr.properties

etc...

and my app host page will be accessed like this for example http://blabla/MyAppHostPage.html?locale=en&id=men and this must load english version for men.

Thanks.

How about using fictional locale identifiers such as en_US_Men and en_US_Women and so forth for other locales? (note that you should include a country whenever you include a variant of a locale)

Otherwise, I'd suggest using an abstract factory for your Messages and switch the concrete implementation using deferred binding on a distinct property (men vs. women):

interface MyAppMessagesFactory { MyAppMessages create(); }

class MyAppMessagesFactory_Men implements MyAppMessagesFactory {
   @Override
   public MyAppMessages create() { return GWT.create(MyAppMessages_Men.class); }
}


class MyAppMessagesFactory_Women implements MyAppMessagesFactory {
   @Override
   public MyAppMessages create() { return GWT.create(MyAppMessages_Women.class); }
}

You'd then have your MyAppMessages_Men_en.properties and MyAppMessages_Women_en.properties.
