Establishing the Locale
To get the correct strings for a given user, a web application either retrieves the locale (set
by a browser language preference) from the request using the getLocale method, or
allows the user to explicitly select the locale.
A component can explicitly set the locale by using the fmt:setLocale tag.
The locale-config element in the configuration file registers the default locale and
other supported locales. This element in Duke's Tutoring registers English as the default
locale and indicates that German, Spanish, Portuguese, and Chinese are supported locales.

<locale-config>
<default-locale>en</default-locale>
<supported-locale>de</supported-locale>
<supported-locale>es</supported-locale>
<supported-locale>pt</supported-locale>
<supported-locale>zh</supported-locale>
</locale-config>
The Status Manager in the Duke's Tutoring application uses the getLocale method to
retrieve the locale and a toString method to return a localized translation of a student's
status based on the locale.

public class StatusManager {
private FacesContext ctx = FacesContext.getCurrentInstance();
private Locale locale;
/** Creates a new instance of StatusManager */
public StatusManager() {
locale = ctx.getViewRoot().getLocale();
}
public String getLocalizedStatus(StatusType status) {
return status.toString(locale);
}
}
