Wrong codepage

Hi! I'm create simple Vaadin project (using Vaadin 6.7.6). I'm create simple Login form from com.vaadin.ui.LoginForm

LoginForm login = new LoginForm();
        login.setLocale(Locale.getDefault());
        login.setWidth("100%");
        login.setHeight("300px");
        login.setCaption("Вход в систему");
        login.setDescription("Вход в систему");
        login.setLoginButtonCaption("Войти");
        login.setPasswordCaption("Пароль");

My messages in Russian, but in browser i see it in wrong codepage. How can i fix it?

I think it is the same problem as with german, see this thread for a fix.

Thanks! But i discover that Russian text not correctly display in each Vaadin component. For start my project i'm using JBoss 7.1.1. Is that problem in JBoss ?
