I want to write a tigase (a xmpp/jabber server) plugin and tigase is published under GPL3.

My plugin would use xmpp extensions to add needed functionalities.

The plugin would be load at runtime.

If you use/include/link-to any code that is under GPL, you need to publish it under GPL. Check the plugin API. If you interact with GPL software, you don't need to GPL your code in the same way as my GIMP-drawn image isn't GPLed.

If you downvote, it's good to leave a comment explaining why. Otherwise, chances are someone will just upvote it again to balance things out.

Yes, your plugin would have to be GPL.

But if you don't give a binary of the plugin to anyone (just run it on your server), you don't have to give the source code to anyone, even if it's GPL.
