Question about jar functionality

I have a jar with a bunch of classes in it, and they were compiled with specific class paths on another machine. I want to add another class to this jar, so I extracted the files and added my class and repacked the jar, under the same file structure. I assume that doing this has zero effect on any of the other classes in that jar. So when I put the jar back into the system, the other classes should still work fine, correct? In short, I'm wondering if packing classes into jar has any effect on classpaths.
