Using the client locale in a server service [message #1236833]

Some of our databases contain NLS data (i.e. a column for each language) and we want to return the correct text in our LookupServices for those tables.

Is there a mechanism provided by scout to find the locale of the client currently using a server service?

If not, what is the recommended way to pass this information from client to server? I'd prefer a solution that passes this information from client to server once at client startup over a solution that forces me to pass this information on each call to the service.

From what I know/remember, scout does it for you. I think it works with Locale of the thread.

If you use TEXTS.getText(...) in the server scout will set the appropriate language (depending on the locale of the client). [you can confirm this very easily].
If you need to do it by yourself, I imagine you can have a look at how the Text service is solving it.

Thanks for your answer, Jérémie.

I've had the same idea and traced the TEXTS.get(key) call as far as DynamicNls.getTextInternal() where there is the following line:

if (locale==null) {
locale = getDefaultLocale();
}

which in turn calls NlsUtility.getDefaultLocale();

So in my code I use
Locale locale = NlsUtility.getDefaultLocale();
and then switch on the language.

It's quite embarrassing, but it was a simple bug (comparing a locale against a string) which caused my code to always use the default case Wink

Now that I'm comparing the correct fields everything works fine!
