The following example program demonstrates very simple program for implementing this concepts. if you look into the faces-config.xml file,locale-config element is used for specifying the default locale and supported locale information. In this sample application we have provided default as English and supported as French.
Use resource-bundle element to specify the name of the properties file to be used. For example if you create a resource bundle name as Messages, then all the language letters will be suffixed with the file name.In our case French locale is named as “Messages_fr”.The default will be “en”, it is not required to specify explicitly.
