[2.1 - java] How change language to use in templates

[Adis]

Hi,

I am pretty confused how to change the language in a Play 2.1 application. In 1.2 you used : 

Lang.change("");

But in 2.1, this is much harder. What I MUST have in my webapp (sell and buy platform that I am about to build): 

On the frontpage the user can choose his language, but how to change this in the application, so that I get the correct language back when I call the Message class from the controller or template?

When the user changed his language he can buy something from another user whose language can be completely different. So when I want to inform both users, I should call:

Messages.get(new Lang(user.getLanguage()), "my.translation.key");

I have seen this pull request by Julien: https://github.com/playframework/Play20/pull/325, but no idea how to use it in my Play Java App?

Thanks!

Invoke the changLang method from inside the controller?

Just like Nilanjan said, it can be done with method similir to 1.2.5 :-)

public static Result change(String langCode) {

    changeLang(langCode);

    Logger.info(Messages.get(new Lang(Lang.forCode("ru")), "welcome"));

     return ok(index.render("welcome"));

    }

method changeLang() will change the applications Language.
