Have made a small game that I want to share with others.

Netbeans lets me generate a jar file.

It works perfect on my own computer. But on others a part of it doesnt work.

Am pretty sure its only the functionality in this method which causes problems.

Maybe its the declaration of a file in line 3.

Can someone help ?

Code
   private void verdenskortMouseClicked(java.awt.event.MouseEvent evt) {                                        
       hint.setText(givhint());
      File file = new File("src/Kort/verden.jpg");

       try {            
           BufferedImage image = ImageIO.read(file);
           int x = verdenskort.getMousePosition().x;
           int y = verdenskort.getMousePosition().y;            
           int farve=image.getRGB(x,y);
           //System.out.println("x "+x+" y "+y);
           if("Antarktis".equals(givOmr(farve,x,y))){
           detsker.setText("Antarktis");
           }
           if("Sydlige Ishav".equals(givOmr(farve,x,y))){
           detsker.setText("Sydlige Ishav");
           }
           if("Arktiske Ocean".equals(givOmr(farve,x,y))){
           detsker.setText("Arktiske Ocean");
           }
           if("Atlanterhavet".equals(givOmr(farve,x,y))){
           detsker.setText("Atlanterhavet");
           }
           if("Indiske Ocean".equals(givOmr(farve,x,y))){
           detsker.setText("Indiske Ocean");
           }
           if("Stillehavet".equals(givOmr(farve,x,y))){
           detsker.setText("Stillehavet");
           }
           if("Nordamerika".equals(givOmr(farve,x,y))){
           detsker.setText("Nordamerika");
           }
           if("Sydamerika".equals(givOmr(farve,x,y))){
           detsker.setText("Sydamerika");
           }
           if("Europa".equals(givOmr(farve,x,y))){
           detsker.setText("Europa");
           }
           if("Australien".equals(givOmr(farve,x,y))){
           detsker.setText("Australien");
           }

http://stackoverflow.com/questions/2393194/how-to-access-resources-in-jar-file

1) why do you have a src folder in your jar?
2) you seem to know how to use a logger. why aren't you logging to determine the problem?
3) if (!file.exists()) // handle error

And code in English. It's pretty vital for code you wish to share that it is English. Folk aner sgu ikke hvad harer og geparder er. ;)

Thanks for advise both of you.

Dont know much about jar files. Java just generates it for me.

The jar file works perfect on my own computer but not perfect on others.

all the pictures show up as they should. and you are able to click most of them as you should.

But there is a world map where you should be able to click. On other computers than mine nothing happens when you do.

So pretty sure it is this method that is causing the problem in the jar file.

1. Dont understand. I can not open my jar file. When I click on it the program runs. My netbeans project is called Gratisdyr. in "src" folder there are "Kort" folder with pictures and "gratisdyr" folder with logical classes.
2. I dont know how to use a logger. How do u do that ?
3. The file does exist when I run netbeans. But not sure whether it does or not when others runs my jar file.

jar files are just zip files with your class files and resources inside. you'll see a manifest which provides the classpath and tells you which main method is invoked.

rename xxx.jar to xxx.zip and unzip it and you can see whats inside.

it's this.... though it's best to create the logger object as a static field in the class
Code
} catch (IOException ex) {
          Logger.getLogger(Spilleplade.class.getName()).log(Level.SEVERE, null, ex);
      }

Thanks.

Think I understand it a bit better now.

So the code line:
File file = new File("src/Kort/verden.jpg");
will make no sense on a computer different than mine ?

But a line like this setting a label is working fine.
k1.setIcon(new javax.swing.ImageIcon(getClass().getResource("/Kort/"+s.hand1[0]+".jpg"))); //

This works..

InputStream is = Main.class.getResourceAsStream("verden.jpg");
BufferedImage image = ImageIO.read(is);

Finally ot in.
Thanks all
