Since I'll be switching to a new launcher soon, I thought I'd ask whether anyone is using the JNLP files hosted on the website for custom clients (like, for the resource Jars, or for JOGL). If you are, those JNLP files are going to become invalid sooner or later, so you probably shouldn't.
If you want to use the same launcher as I do, the source code is at <git://sh.seatribe.se/launcher>. The launch file for the default client is at http://game.havenandhearth.com/java/hafen.hl, and the default bootstrap file (the one that is included in the launcher Jar) at http://game.havenandhearth.com/java/bootstrap.hl.
