Hi,
I use org.apache.tapestry5.ioc.Messages to get the translated
strings for
my web application from the property files for my pages. This works
great.
Now, I want to use the same mechanism in two different places in my
application:
1. A user can click a button to generate some graphic or Excel file
containing data. Some strings on the graphic (like title, ...) and
in the
Excel file need to be translated, too. So in the code, which
creates the
graphic or Excel file, I pass the org.apache.tapestry5.ioc.Messages
instance, which was injected into my page to do the translations.
This also
works great. But: sometimes the language used for the graphic or
Excel file
is different from the language used on the web page. How can I make
the
Messages instance switch the language, or request a new Messages
instance
from Tapestry, with the language (Locale) needed for the graphic /
Excel
file?
You can use LocalizationSetter.setNonPeristentLocaleFromLocaleName
to change
the locale without affecting the client locale current locale.
Tried this out with some simple code in a Tapestry page:
...
@Inject
private Messages messages;
@Inject
private LocalizationSetter localizationSetter;
public String getMixedLanguageContent()
{
String str=messages.get("apple");
localizationSetter.setNonPeristentLocaleFromLocaleName("de");
str=str+", "+messages.get("apple");
return str;
}
...
${mixedLanguageContent} in the .tml file.
but it seems the Messages instance does no change the locale just by
using a localizationSetter, as the ouput is:
apple, apple
instead of
apple, Apfel
2. The application runs some scheduler, which will create reminder
emails
once every day. The emails are create from a template, which is
filled with
some translated strings. Is there an easy way to ask Tapestry for a
Messages
instance (with a given Locale, and based on some class (to query
the right
.properties file) as if it were injected into a page), in this
background
job, which just runs inside a web application, but does not have any
connection to an actual web request?
Have a look at
http://tapestry.apache.org/tapestry5/tapestry-ioc/parallel.html
This document describes a mechanism for running threads. I will
probably use some Spring functionality for scheduling my threads, so
this part is already handled. The only thing missing is how to get
hold of a Messages instance for a given Locale and a given class,
without being a Tapestry page and relying on injection? Is there a way
to let Tapestry inject this Messages instance into my Spring managed
classes? Or is there something like MessagesUtil.getMessages(Locale
locale, Class clazz) to request the appropriate Messages instance from
Tapestry?
Thanks,
