What does locale="true" really do?

["Kurosaka, Teruhiko" <Te...@iona.com>]

Hello,
Various documents suggest that we are supposed to say:
<html:html locale="true">
in Struts-based JSP files.  This directive somehow sets
the locale automatically, as I understand it.
But I am wondering exactly how Struts sets a locale.
Does anyone know?

I am hoping that Struts won't just blindly pick up the
language of the heaviest weight in the request's
Accept-Language header, because that is simply
wrong.  When there is no German version of a .jsp
file, "accept-language: de" should not be honored,
for example.  I am hoping that somehow Struts knows
the list of available languages for a page, but I cannot
seem to locate that description.  Does anyone know
anything about it?

The implementation of this tag grabs the current locale from the session
(set from either a call to request.getLocale() or later updated by the
application) and uses that to set the "lang" attribute on the <html> tag.

Struts doesn't know anything about this, because "languages available" is
an application specific concept.  However, your application is
free to set the Locale (in the session, under key Action.LOCALE_KEY) to
whatever you think is correct.
