Add folder to my .app on Mac OS X

I have a java applicat开发者_开发技巧ion and want to create a .app for it using the jar bundler on a Mac, but my problem is that I have some of my resources in a folder and the jar bundler only allows me to add files or resources and not folders. So if anyone has any solutions please share it here. Otherwise i would have to keep all my resources in a single folder and change the code accordingly.
