I use NetBeans IDE 4.1. I wrote 5 classes one of them is the main class. All the code is free of errors, I tested it very well, and it does work as it should (as expected)
I am new in producing executable files, I discovered later that netBenas produces jar files automatically found in dist folder. OK now I have (jar) file for my project (the one described above), but when I double-click on the icon, simply nothing happens.
I have many other projects that are launched after double-clicking their jar file, but I noticed that those projects usually contain only two related classes the main one and the one that has the working code. (does it matter?).
