To add a new language, you need to add the corresponding language node in the locale-config.xml file. Next, you must create a new resource bundle file containing the suffix name as the key of the added node.
For example, to add Italian, do as follows:
1. Add the following node to the locale-config.xml file.
<locale-config>
<locale>it</locale>
<output-encoding>UTF-8</output-encoding>
<input-encoding>UTF-8</input-encoding>
<description>Default configuration for Italian locale</description>
</locale-config>
2. Create a new resource bundle as webui_it.properties in the myextension.war/WEB-INF/classes/locale/portal folder.
Note
This step is necessary because the Resource Bundle Service of the portal will find keys and values in the resource bundle of each corresponding language.
3. Restart the server.
To check if the added language takes effect, hover the mouse over your username on the Administration bar and click Change Language. In the Interface Language Settings window that appears, you will see the Italian is listed as below:
