Localization Support in Identity Server

This page describes how WSO2 Identity Server can be configured to support localization of its UI:

Configuring Localization for Authentication Endpoints

WSO2 Identity Server provides internationalization support for the web apps (such as authentication endpoint which is in <IS_HOME>/repository/deployment/server/webapps/ directory). The following steps describe how you can configure this:

1. Navigate to <IS_HOME>/repository/deployment/server/webapps/authenticationendpoint/WEB-INF/classes/org/wso2/carbon/identity/application/authentication/endpoint/i18n/

2. Take a copy of the Resources.properties file, rename it with the required locale suffix as follows: 
   Ex: For British English: Resources_en_GB.properties
         For French (Standard): Resources_fr.properties

   Refer Web browser language identification codes for more information on required locale suffixes.

3. Update values while keeping the keys as follows,
   Ex: login=<Value in the required locale>
4. Save the file.
5. Go to the browser setting and add the language you configured above.
6. Restart the server.

To try out, do the following: 

1. Open up a browser.
2. Type the dashboard URL. (If you are running the server in your localhost, the URL is: https://localhost:9443/dashboard/). You will see the login screen having the contents in the configured language.

If you want to have internationalization of error messages coming from authentication-framework/oauth-framework, Follow the below steps:

First, you need to generate a key from the message itself for the i18n, properties file. following steps below:

1. Get the message "oauthErrorMsg" from URL and do URLDecode 
2. Base64 Encode the message "oauthErrorMsg"
3. Replace = with _ in the base64 encoded message

Now look for a value in Resource.properties file with the relevant locale. If a match is found, define a value for the property. Otherwise use add new property entry to the relevant locale based on the Resource file, as explained above. If you don't specify a value for the key obtained after #03, the error message itself will be displayed in the UI, as default.
