I am confused at what is going wrong here. I believe its something wrong with the way JFrame is set up. There is also a generator class but I think if I can get the launcher working then the Generator will come after. Any help is greatly appreciated!

here is my source code:

main:

public class Main {
static Launcher launcher;

    public static void main(String[]args){
        launcher = new Launcher(); 
    }
}

Launcher:

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

  • Have you specified the main class so that the manifest can be updated? – MadProgrammer Oct 14 '14 at 01:13

    Are you exporting it to a jar? If so, your files will no longer be files and instead will need to be accessed as resources and will need a different relative path. Also as an aside, your code is suffering from gross static overload. – Hovercraft Full Of Eels Oct 14 '14 at 01:16

  • I see public void lsetVisible(...); and then I don't see it being called anywhere, perhaps that is a problem??? Prolly a stupid point, but thought it is worth mentioning – DreadHeadedDeveloper Oct 14 '14 at 01:43

  • Thanks guys I believe my error is within getting the list of files in the directory. In setDirectories tslist is null – user2853442 Oct 14 '14 at 05:14
  • FIXED! it was my directories. thanks for the help. – user2853442 Oct 14 '14 at 05:20
  • Good. Did you also fix the other issues with your code? Have you made most of your fields non-static yet?' – Hovercraft Full Of Eels Oct 14 '14 at 11:05
  • Yes all my fields are non static except for a small few. – user2853442 Oct 15 '14 at 16:15
