Translate Application- browser application based on the language defined

Question

Dear All Expert,
My oracle apex application is develop in oracle 11g XE edition, apex application primary language is in english. And i would like to switch my application to chinese language based on the language defined on my oracle database table.
I did translated my application to chinese language and published.
I created application processes called "set_language", the conditions type is "Request = Expression 1" and i set "Expression 1" to value "LANG". (Fire on header load)
setlanguage pl/sql as below;_
begin
owa_util.redirect_url('f?p='||:APP_ID||':'||:APP_PAGE_ID||':'||:APP_SESSION);
end;
I created a button with label "chinese" on my login page. This button will send a request "LANG" and set "FSP_LANGUAGE_PREFERENCE" to value "zh-tw" ,and redirected to my login page again when button pressed. This work fine.
My question here is how can i automatically browser the apex application based on the language defined on my database table. (I had a table to stored language to be use browser the application.) Mean that i want my apex application to check the language from my db table in order to browser the application based on the language defined.
How can i do that? Can anyone help on it?
Another question is about the logout in chinese language display.
The application will automatically switch to english when i logout my application. How can i maintain in chinese language?
Thanks a lot in advance!
Best Regards,
Apex Junior.

Hello, (What is your first name?)
>> I tried to used session as derived my second language which is "zh-tw".
The Session option allows you to use the built-in procedure apex_util.set_session_lang or the parameter p_lang - as part of the application URL – to dynamically set the application language.
If you use the p_lang parameter as part of your application URL, the first page – including the login page – will be rendered according to this parameter. In your case it can look something like this:
http://. . ./f?p=1234 . . . &p_lang=zh_tw
>> From your reply, you are suggested to use APPLICATION PREFERENCE(FSP_LANGUAGE_PREFERENCE).
As I mentioned in the last paragraph of my previous reply, if you choose to set the application language for each individual login, based on a parameter you need to fetch (like the database language), you don’t need to use application preference. The latter is useful when the user preference is lasting (i.e., a certain user is using the same language all the time, although you have the option of changing it). If the language can change from one session to another, based on dynamic parameters in the database, the best is to use the * FSP_LANGUAGE_PREFERENCE* item.
The advantage of using the p_lang parameter is that it allows you to set an appropriate language even for the first application page (usually the login page). Using the FSP_LANGUAGE_PREFERENCE item requires you first to set its value. Before that, the Application Builder uses the primary language to render the first page, and because of that, the first rendering of the login page is in the primary language.
I want to draw your attention to the Browser (use browser language preference) option. If your application language tightly correlated with the browser language – it’s reasonable to assume that users that want to use zh-tw in the application, also using the same language in their browser – this option is a very simple and straightforward to set the application language from the first page.

Arie.
