I'm trying to listen keyboard events in Java by using a third-party library from "net.java.games.input". When I run my code in Eclipse, it works fine. But when I build my project and run the .jar, it does not. The reason I guess, the library needs some .dll files to listen my keyboard and they don't work in .jar.

Here's my code example;

ControllerEnvironment ce = ControllerEnvironment.getDefaultEnvironment();
Controller[] ca = ce.getControllers();

So, what should I do to make this work in a .jar?

Thanks.

  • i have a look to your librairy (here : https://github.com/sgothel/jinput/tree/master/coreAPI) i saw no dll involved , even it work on linux so i am pretty sure that they are none , i think that more a build issue . how do you generate you jar ? can you make a simple sample of code that fail or the exception throw? – Arnault Le Prévost-Corvellec Jun 19 '18 at 11:54
  • @ArnaultLePrévost-Corvellec When I run the code without .dll files, I got this exception; java.lang.UnsatisfiedLinkError: no jinput-dx8_64 in java.library.path – josh Jun 19 '18 at 13:22
  • your issue will be the same if eclipse didn't did this automatically^^ – Arnault Le Prévost-Corvellec Jun 19 '18 at 15:35

You can use System.loadLibrary() to let the JVM loading your dll or System.load() to load file from a specific path:

static {
    System.load("PATH/TO/file.dll");
}

so your issue is relative to this

JInput "no jinput-dx8 in java.library.path" Error

You should set java.library.path property to point to the directory containing native dlls of JInput. You can do it by adding -Djava.library.path=x (where x is your path) to the command line or to the "VM arguments" field of "Run configurations" dialog in Eclipse.

you can also at the beginnning of your main do this

System.setProperty("java.library.path", System.getProperty("java.library.path")+";thePathOfYourDll");
