Changing Header.vm file on Locale change
Hi
What i want to do is that whenever i change "Locale " of my application
depending on that locale i want to change my
"header.vm" files contetnt for Meta tag.
On my first page i am having one link that will chage my "Locale " of
application now suppose i click on link and now new Locale is "en" then i
want <meta > tag for en to be used by browser.
Whenever i change my Locale one portlet is called and that calls another
class to set this locale in session for that user. I tryid to put that in
Velocity context but
Now i am very much new to this velocity and trying lot many things but
getting nothing.
And my big confusion is that is this "header.vm" is called before that
portlet is called.
Can anybody give me proper direction please.
Thanks

nope, i don't use Jetspeed. you would have better luck asking on
their user mailing list, rather than asking on the Velocity list.

Re: Changing Header.vm file on Locale change
Posted by santas <be...@yahoo.co.in>.
Thanks for your reply
but i think i missed one point here that i am not using
velocity for my front end. I am using jsp with the portlets. And i think i
cant use this #parse( ) here in jsp.
I tryid solution but i don't know whether it is standard
or not.
What i tried to do is whenever i change "Locale" of my application it calls
on class,ok
now int hat class i added following code
VelocityEngine Velocity = new VelocityEngine();
Properties p = new Properties();
p.setProperty("file.resource.loader.path",
"C:\\Jetspeed-2.0\\webapps\\jetspeed\\decorations\\layout");
VelocityContext context= new VelocityContext();
context.put("langname",strLanguage);
Velocity.init(p);
Template temp = Velocity.getTemplate("tempheader.vm");
StringWriter writer = new StringWriter();
temp.merge(context,writer);
byte[] test= writer.toString().getBytes();
FileOutputStream out = new
FileOutputStream("C:\\Jetspeed-2.0\\webapps\\jetspeed\\decorations\\layout\\header.vm");
out.write(test);
out.close();
now i had written on file called "tempheader.vm"
#set ($MESSAGES =
$portletConfig.getResourceBundle($renderRequest.Locale))
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="#BaseHref()">
<meta http-equiv="Content-type" content="#ContentType()" />
<meta http-equiv="Content-style-type" content="text/css" />
#includeJavaScriptForHead()
#IncludeStylesheets()
#if($langname== "it")
<meta>italian meta
data here</meta>
#else
<meta>english meta
data here</meta>
#end
<head>
now whatever output i get by using this tempheader.vm template i write it to
another template that is "header.vm"
now it is working fine now but i dont know wether it is standard approch or
not.
i trying to seach about how this jetspeed container manages file writing for
large no of request.(how it synchronizes all request that write single file
)
Please can you put some light on this
Thanks

Re: Changing Header.vm file on Locale change
Posted by Nathan Bubna <nb...@gmail.com>.
This looks like it might be a good situation to use the
"MultiViewsTool" to find the appropriate header.vm file:
http://velocity.apache.org/tools/devel/javadoc/org/apache/velocity/tools/view/i18n/MultiViewsTool.html
I haven't used it myself, but my understanding is that you use it to
find the appropriate template name for a specified locale (or the
default locale if there is none for the specified locale). And then
you use the #parse() or #include() directives to load that
template/file.
So, assuming that you are using VelocityTools and the MultiViewsTool
is in the context as $i18n, you would probably do something like:
#parse( $i18n.findLocalizedResource("header.vm", $request.locale) )
of course, i don't know if you are using VelocityTools or the
VelocityViewServlet. You mentioned portlets. Are you using a
specific portlet framework? You might consider asking them for advice
on this too. It could be challenging to set up VelocityTools with
that framework; i'm not really sure how that would work...
