Thread:Project:Support desk/Translate/File Format Support Extension - Sample

How can I make Java properties files uploadable using the File Format Support Extension (Translate Extension)? Is there any sample? I'm also completely new to WikiMedia programming and would appreciate any help.

So, basically I would like to use the FFS interface described in http://www.mediawiki.org/wiki/Help:Extension:Translate/File_format_support to upload Java properties files (which then could be translated on the Wiki site).
