Goal

In WebCenter Custom Portal Application, in some cases, you may want to allow user to specify their preferred locale in the application rather than using the browser default locale so that the page can be displayed in the user preferred language.

By default, the locale is selected based on the HTTP request object and specified by the user in their browser settings. To allow users to specify their preferred locale in the application, this class must be used along with a ServletFilter to get the preferred locale, through LanguageSetting.getLocale(), and set it in the ADFContext.

This document is to walk through some of the major steps to implement the switch languages feature.

In this example, I will take the English and Chinese languages as an example.

Here are the high level steps:

1. Create the Portal Bundle to store the English labels and Chinese labels.
2. Create your own Navigation menu, and refer to the PortalBundle and specify the Title
3. Create a backing bean to handle the language switch.
4. Create a HttpServletRequestWrapper that wraps the client HTTP request and overwrite the Accept-Language HTTP header that sent by the browser.
5. Create your Servlet Filter.
6.  Register the Servlet Filter in web.xml
7. Add the adf commandLink to call the backing bean to switch the language.
8. Done, and run the application.
