Java Notifications

Hey guys,

I'm trying to implement notifications for my Chat program in Java but I just can't get it to work.

I have found some nice custom packages, but I have NO idea how to import them properly.
Here's Twinkle. The Demo of Twinkle works properly but I just can't get it to package properly.
I can't find anywhere the installation protocol for Twinkle, but there is a Getting started with Twinkle page. I followed this page, importing it how I thought was write but it errored with NullPointer, if I remember correctly.

Simple example of a nice popup:


is there anyone that can help me with this? I'm using NetBeans by the way.

Thanks!

Try studying the source of some other programs (that are coded in Java) that have notifications, if I knew Java I would help more, but I am only learning it atm, so can't.

What exactly do you mean? You can't import ch.swingfx.twinkle;? Or is there some other problem? Like extracting vs packaging packages into a jar? I don't use NetBeans, so I'm not too sure what the problem is. I'll look at NetBeans, though.
