How to set Locale ?

[A]

I would like to let user choose thier own language. But i don't know how to set Locale in LogonFormController (extends SimpleFormController). Any suggestion?

Since
RequestContextUtils.getLocale(Request).getLanguage ()= th
But
RequestContextUtils.getLocale(Request).getCountry( ) = empty string
So currency format shows improper. Then I would like to set a default Locale and let user change it as well. Could you please give me some example?

Thank you in advance.

You may review countries sample from Spring distribution. It shows how to configure/use multiple Locales.

Countires source is included in Spring distribution. Look inside $SPRING_ROOT/samples/countries.
