Question

I hava a jar with a main file like this:

public class StartMesekocka3D {

    public static void main(String[] args) {
        try {
            Runtime.getRuntime().exec("java -Djava.library.path=\"bin\" -jar \"Mesekocka3D.jar\"");
        } catch (IOException ex) {
            Logger.getLogger(StartMesekocka3D.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

I’d like to start an other jar with a djava argument. If i double click on the jar (they are in the same folder of course), nothing happens, if i type java -jar Startmesekocka3D.jar it’s starts the other jar, and works perfect. What should be the problem with double clicking?

Answer 1

for creating an executable jar which can be started by dbl clicking, you need to define Main Class entry in manifest.mf and then jar it with the new manifest.mf
