I don't know what you mean by "proper" packaging. The .app wrapper was created using Apple's official JAR wrapping utility. It follows all of Apple's standards for making applications.
If you want some guidance on making .app wrappers for JAR files, start with step 7 in the "How to build JPCSP for yourself" part of this thread (you'll need to be sure that you've downloaded XCode):
