I use install4j for my application distribution. But I didn't get any information in case when I want add custom language (not from available list). For example ukrainian(UA). Is it possible ?
You can add a new language like that:
Edit the file resource/messages/languages
and add the line
ua=Ukrainian
Add the line
languages.ua=Ukrainian
to the file resource/messages/messages_en.utf8
Copy the file resource/messages/messages_en.utf8
to resource/messages/messages_ua.utf8
and translate all messages.
We are happy to ship and subsequently maintain a new translation if you send it to us.
