Eclipse when export runnable jar program doesn't work

Question

I have a project in Java but when I export a runnable jar, the program doesn't work. Can anyone help me?

Here is my project code:

maybe you're missing some directorys by your jar (like [here](http://stackoverflow.com/questions/29082094/runnable-jar-file-not-working-first-to-third-exports-is-working-but-several-expo)in the comments) — Zorian, Mar 17 '15 at 08:07
What is it showing? Please update the question with error logs and more info about the problem you are facing. Also it is worth mentioning how you exported the runnable jar. — includeMe, Mar 17 '15 at 08:08
run your jar from the command line with "java -jar yourjar.jar" to be able to see any errors it generates — Subler, Mar 17 '15 at 08:08
1) Java GUIs have to work on different OS', screen size, screen resolution etc. As such, they are not conducive to pixel perfect layout. Instead use layout managers, or [combinations of them](http://stackoverflow.com/a/5630271/418556) along with layout padding and borders for [white space](http://stackoverflow.com/a/17874718/418556). .. — Andrew Thompson, Mar 17 '15 at 08:09
.. 2) Application resources will become embedded resources by the time of deployment, so it is wise to start accessing them as if they were, right now. An [tag:embedded-resource] must be accessed by URL rather than file. See the [info. page for embedded resource](http://stackoverflow.com/tags/embedded-resource/info) for how to form the URL. — Andrew Thompson, Mar 17 '15 at 08:12
@Jens when i run in the eclipse everything okey but when i exported and try to open .jar not opening anything. i am beginner for java — Hayrettin Çetintaş, Mar 17 '15 at 08:15
Please follow the advice offered by @Subler more than 30 minutes ago! With the information from the command line, we might have identified the problem by 20 minutes ago. — Andrew Thompson, Mar 17 '15 at 08:44

I think your problem is the relative path in the following line:

final File folder = new File("Fonts/");

I suppose your jar file is not in the same folder as the "Fonts" folder. So it can't find the path "Fonts/", when you run the jar file.

Try copying your JAR file on the same level as the "Fonts" folder and try it again

/PATHONYOURLOCALDISK/Fonts
/PATHONYOURLOCALDISK/yourjar.jar

Moving directories around is at best a debugging technique. This answer should really be a comment, given you are making guesses.. – Andrew Thompson Mar 17 '15 at 10:34
