This has been deprecated in 1.2.

My internationalized pages appear not to need this at all 
     

with 1.2. The 
   

Locale seems to get detected from the browser just fine without it.

Since, I never got around to serious internationalization 
     

while I was 
   

using 1.1, I thought this was necessary for the jsp page to 
     

auto-select 
   

it's locale. Am I misunderstanding what the purpose of locale="true" 
was?

If not, how have things changed? Is it now assumed to be the default 
unless a lang specific lang parameter is specified in the 
     

html:html tag 
   

or something?

Basically it seems like it just went away, and now the 
     

functionality it 
   

provided now shows up when it's needed "as if by magic", 
     

which I'm sure 
   

ain't so. :-)

What exactly has changed here? I'm kind of curious (and 
     

okay, somewhat
   

suspicious) now...



     

No conspiracies here :-).  The deprecation comment about the "locale" 
attribute explains what is going on, and the description of 
the "lang" 
attribute describes the algorithm that is used.
http://jakarta.apache.org/struts/userGuide/struts-html.html#html

This page, like all the rest of the Struts documentation, is also 
available locally if you unpack (and perhaps deploy on a server) the 
struts-documentation.war webapp.
   

Actually, this page is what made me _start_ scratching my head...If I
hadn't seen it, how would I known to ask about the lang attribute? :-)
So let me better explain myself.

In reading it before I made the assumption that lang was to specify the
language for the page like this: <html:html lang="en">, and if I wanted
the same functionality as before I needed to do something like
<html:html lang="<%=language%>">. In reading it now, I'm gathering
that's not the case :-), but anyway I figured I'd find the answer by
experimenting a little...
And <drum roll>...without specifying Locale OR Lang, it displayed in
Russian like a champ when I told IE6 to make Russian the primary
language it looked for!
I was thusly inspired to post my question: Since it worked without
specifying it, what does this tag really do for me? Under what
circumstances do I really need to have this type of thing specified?
 

You don't need it at all if you're willing to let the user's language 
selection in the browser control everything (which is the default 
behavior).  If you want to offer a "change Language" control, you'll 
need to use either lang="true" or locale="true" (and make sure there's a 
session) so that Struts can keep track of the user's non-default locale 
choice.
