So I was wondering how other projects deal with platform specific launching / java verification.

I'm thinking specifically about Windows. Also I've seen games that used some almost compiled like launcher, aka Minecraft.

What/is there a standard packaging procedure for games built with LWJGL?

There are a number of different methods available to distribute LWJGL applications, a brief overview can be found here.

If your looking for Minecraft like launching with LWJGL, then you are looking for the LWJGL AppletLoader, there is a full 4 part tutorial for it here which explains what it is, how to use it and various tricks to deploy applets nicely with LWJGL.

Thank you!! This is exactly what I was looking for.

I'm a moron. I didn't even think to check the faq.
