Developer can define new or remove a defined language through the locale configuration file. The resource is managed by org.exoplatform.services.resources.LocaleConfigService as following:

<component>

    <key>org.exoplatform.services.resources.LocaleConfigService</key>

    <type>org.exoplatform.services.resources.impl.LocaleConfigServiceImpl</type>

      <init-params>

        <value-param>

          <name>locale.config.file</name>

          <value>war:/conf/common/locales-config.xml</value>

        </value-param>

      </init-params>

  </component>

All languages defined in the locale-config.xml file are listed in the Interface Language Settings window.
