Question

I am trying to write a program in Java, which would collect a specified set of files from the physical location and place them in a jar in a certain directory.

I know I can use java.util.jar package for this. The package is great for sure, but I was wondering if there are any third party libraries that anyone at SO has used which they could recommend.

TL;DR: pick up files, create jar by placing them in pre-defined directories, all at run time in a java file.

P.S: I did not find any similar references to this question, but if there are then please refer me. Also, the title might be misleading, but I didn’t find better words to explain my problem.

EDIT 1: I am not in anyway saying java.util.jar is bad or incomplete. All I am asking is if anyone has used any alternative solutions!

EDIT 2: I am trying to create the jar from inside the java program. The jar can be pretty big (~500mb) too. Trying to jar media files as well. So simply put, I pick up various files from certain locations on my drive and try to create a jar file by placing them in standard locations.

Thanks,
Ivar

Look at the java.util.zip package. Jars are just zip files with some extra stuff in ’em
