Answer 1

It could be lot's of reasons. What is the error message? Try to catch an Exception with try catch block and save it to some file, then read it.

Answer 2

Move the jar to another directory on your computer and double-click it there. It should not run there. Otherwise you have used File-s instead of resources (getClass().getResource[AsStream]()).

Do not throw away exceptions: so a command line run (cmd) with java -jar ... will show any exceptions.
