The Openfire admin console can be easily translated into other languages. This document provides instructions for those that wish to make translations.
All text in the Openfire admin console is stored in a resource bundle. A resource bundle is a file containing key/value pairs. Words and phrases are represented using keys. The correct values are retrieved based on locale settings (English values are used for English locales, French values for French locales, etc). Key/value pairs in the English resource bundle might look like the following:
skin.yes=Yes skin.no=No skin.topic=Topic skin.message=MessageThe German resource bundle would contain the same keys, but different values:
skin.yes=Ja skin.no=Nein skin.topic=Thema skin.message=BeitragMaking your own translation involves copying the English resource bundle, renaming the file, then translating its contents.
To start, make a copy of the default (English) locale file "openfire_i18n.properties". It can be found in the resources\i18n directory of your Openfire installation. Note: the files found in resources\i18n are copies of the real resource bundles used by the application (the real resource bundles are contained in the openfire.jar file). Editing the resource files in the resources\i18n directory will not affect your running copy of Openfire.
Next, you'll need to rename the file to match the locale that you're making a translation for. The syntax of the name is "openfire_i18n_[lang]_[country].properties". However, the country code should be used in most cases. For example, the German resource bundle should be named "openfire_i18n_de.properties" because "de" is the language code for German. For French, the file would be called "openfire_i18n_fr.properties". A list of language codes can be found at: http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt. Some locales require a combination of language and country code. For example simplified Chinese would have the name "openfire_i18n_zh_CN.properties" while traditional Chinese would have the name "openfire_i18n_zh_TW.properties".
Next, use your favorite text editor to translate the English values into your language. The key names must not be changed.
To test your translation, copy the translated resource bundle file (example, openfire_i18n_de.properties) to the lib/ directory of your Openfire installation. Make sure Openfire is stopped and then edit the conf/openfire.xml file. Set the locale property to match your new resource bundle such as "de" or "zh_CN". Start Openfire and the admin console should now be using your translation. If you still see English text you may have named your bundle incorrectly or used the wrong value for the locale property.
Once your translation is complete and tested, please submit it to the Openfire developers so that others can enjoy it in the next release!
