Fatal Exception occurred when trying to execute a JAR file

Question

Hi,
I have compiled my project in a jar file with the purpose of having an 'almost' executable file that would run with a simple double click.
When running this file from the netbeans directory, it works fine, but if I move this jar file to, say, my desktop, then I get an error:
Fatal Exception occurred. Program will exit.
Is this normal?
basically, I would like to create a stand-alon file that I can send to other people who can run it on their machines
Am I doing the right thing, or missing something?
P.S I should add that my application needs to read contente from some txt files which are stored in my PC, but that is clearly speficied in the code
thanks

Answer 1

I found that if I copy the whole of the dist directory and subdirectories, it works fine. I guess that's what could not be found.
just for my learning, is that the correct solution: basically send over the whole dist+subdirectories and have the program run from there?
thanks
