The LocalePolicy framework is enabled for portlets by configuring the LocalizationLifecycle class in portal's webui configuration file: gatein.ear/portal.war/WEB-INF/webui-configuration.xml.

<application-lifecycle-listeners>

...

    <listener>org.exoplatform.portal.application.localization.LocalizationLifecycle</listener>

</application-lifecycle-listeners>

 

The default LocalePolicy implementation is installed as GateIn Kernel portal service via gatein.ear/portal.war/WEB-INF/conf/portal/web-configuration.xml. Here you can change it to a different value according to your needs.

The following fragment is responsible for installing the service:

<component>

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

   <type>org.exoplatform.portal.application.localization.DefaultLocalePolicyService</type>

</component>

Besides implementing LocalePolicy, the service class also needs to implement org.picocontainer.Startable interface to get installed.
