How to change alfresco webclient language externally

[dynamolalit]

Hi,

I am using alfresco 3.1.1. with Liferay. Alfresco is supporting 3 languages: English, French & German. Liferay also supports these languages. There is a link to Alfresco on Liferay home page.Now requirement is like this :  when user is on Liferay & has selected German as language, & he clicks on Alfresco link, the Alfresco Web client UI should be rendered in German Language.

I tried this in index.jsp :

// set the language for the current session
      Application.setLanguage(FacesContext.getCurrentInstance(), language);

      // save user preference
      if (Application.getCurrentUser(FacesContext.getCurrentInstance()) != null)
      {
         PreferencesService.getPreferences().setValue(PREF_INTERFACELANGUAGE, language);
      }

But no success.I am struggling with this. Does anyone has any idea?

I need the same thing, somebody knows how to change language into webscript??

I tried
PreferencesService.getPreferences().setValue(PREF_CONTENTFILTERLANGUAGE, locale);

But PreferencesService.getPreferences() is always null, and if I use PreferencesService.getPreferences(fc) ..
FacesContext fc = FacesContext.getCurrentInstance(); is null too!

So, I dont know how to get Preferences inside webscript….

Can somebody help me?

Thank you very much
