Q:

Creating jar file directory across?

At first I have to say, that I've just started learning java a short while ago, so I'm not familiar with the language at all. Due to this, I try to get things done without using an IDE, so I can understand how things work. However, it's not the language that drives me crazy, but the process of making a .jar file.
I have the directories E:\Java\MyLib\mylib.java, E:\Java\Test\PartA\parta.java and E:\Java\Test\PartB\partb.java, which contains my main. mylib.java is a package that gets imported by parta.java, parta.java gets imported by partb.java.
I created a .bat file consulting several tutorials as much as the official specification from oracle about how to use the jar.exe, I've created a valid manifest.txt, I told the programm where it could find the partb.class containing my main, everything gets compiled to its own .class file just fine what tells me that my code is correct, but trying to merge all the files together into one .jar file took me hours without a working result.
According to any instructions I was able to find I'm doing everything right, I tried many different spellings and options, but at the end, either the compiler does not even find the files in the subfolders, or the files are in the .jar, but the javab.class is not able to find them during runtime.
It's sickening. I think I'm missing something, doing something absolutely wrong, but I can't figure out what it is. Any advice would be highly appreciated.

A:

Use an IDE, it makes life so much easier. But, if you insist on doing things the old fashion way, try turning off your antivirus. If that doesn't work, check to make sure your environment variables are set correctly. If all else fails, try reinstalling your JDK.
