The folk over at Java-Gaming.org forum have a pretty cool competition in progress called LWJGL16K. The objective is simple, write a game in 16KB using nothing but the LWJGL Library and the classes that come with the JRE.
It is a very good opportunity to learn, hone your LWJGL skills and have fun.

Deploying Java Applications can be a pain if your application has multiple jars and native libraries. There are the options of using Java Web Start or Java Applets however these are not always suitable.
Executable Jars are an option, however if your project has multiple jars or native files then it can be tricky to use this option.
JarSplice attempts to solve this issue by allowing you to merge all your jars and native files into one, easy to use executable jar file.
