Change the language of Liferay from a Struts Action ?

[Yousri B，修改在13 年前。]

I am developing a struts portlet in Liferay SDK 6

How can I change the language of Liferay from a Struts Action ?

public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        

Thank you

I think this will change the language. May need to tweak things a lil bit to fit your use case.

String languageId = ParamUtil.getString(request, "languageId", "es_ES");

Locale locale = LocaleUtil.fromLanguageId(languageId);

String redirect = PortalUtil.getLayoutFriendlyURL(themeDisplay.getLayout(), themeDisplay, locale);

response.sendRedirect(redirect);

return null;

I add this code but not change language

String redirect = PortalUtil.getLayoutFriendlyURL(themeDisplay.getLayout(), themeDisplay, locale);

// redirect is "/ar/web/guest/test" -> good

 response.sendRedirect(PortalUtil.getLayoutFriendlyURL(themeDisplay.getLayout(), themeDisplay, locale));
        
return mapping.findForward("test.view");

I'm also trying to do similar stuff as customization of the LR language portlet.

The following is my requirement.
1. Add 'All' as saving 'Null' value into LR table.
2. I have to customize by including other fields and submitting as one form.

I was able to create a language hook as adding submit button instead of triggering select changing event from select option but I think I have to create a new language portlet by extracting from LR language source code for my requirement. Can you please give me the direction and specially which action class has to be updated for #1.

Thanks,
Don
