which Locale are you talking about ? the one defined by the user profile ?
The client's language locale.
For example, as I know JBossPortal will check the default language in client's browser and use it as the page language, right?
And how can I force JBossPortal to use a specific language? For example, the language of the client's browser is 'en_US', but I want to force the JBossPortal to display all the pages in 'jp_JP', is it possible in programming level (in a portlet)?
