How to add a new admincommand?

[wongvict]

For example, I want to add the "Appearance" command created by Divinity.
And I want to add the admincommand on my customize server.
As I copy the Appearance.java to the script folder, what else i need to config?

As i got this error message when i test to run it.

You'll need to edit at the based of Emu, and then compile it.
Just an advise, without a basic knowledge of Aion Core Devs, better not to involve yourself in it.
