How to include resource files in the .jar?

Hello,

Please attach resultin *.jar file.

Hi Denis,

Here it is the .jar attached, the resources are already in the .jar, but it is still not showing any icons.

And in the codes I wrote

Icon openIcon = new ImageIcon("src/res/fullscreen_16.png");

My project directory is like

xxxPackage
   |______________META-INF
   |
   |______________src
                                |______________res
                                |                           |______________xxx.png
                                |
                                |______________xxx
                                                           |______________xxx.java


The .jar directory is like

My project directory is like

xxxPackage.jar
   |______________META-INF
   |
   |______________xxx
   |                           |______________xxx.class
   |
   |______________res
                               |______________xxx.png

It's reasonable to not find the resource as there is no resource by the given path. Your resources are accessible from the 'res' entry that is located at classpath, i.e. you can perform call like 'Icon openIcon = new ImageIcon("res/fullscreen_16.png");'

Do you mean that I need to add the aboslute path of /res in the CLASSPATH environment variable?

And build the project using modification of

'Icon openIcon = new ImageIcon("res/fullscreen_16.png");'

rather than

'Icon openIcon = new ImageIcon("src/res/fullscreen_16.png");'

Am I right?

Cheers.

No, you don't need to perform any additional changes at your environment. Just reference the resource without 'src' at your code, i.e. use 'new ImageIcon("res/fullscreen_16.png")' instead of 'new ImageIcon("src/res/fullscreen_16.png")' and everything should be ok.

Thanks. Maybe I did misunderstand you but my project directory structured like this:

My project directory is like

xxxPackage
   |______________META-INF
   |
   |______________src
                                 |______________res
                                 |                           |______________xxx.png
                                 |
                                 |______________xxx
                                                            |______________xxx.java

and if I use

'new ImageIcon("res/fullscreen_16.png")'

no icon will show up because the compiler complains ''can't find file' error using the IntelliJ IDEA IDE to build.

If I change the project structure into

xxxPackage
   |______________META-INF
   |
   |______________res
   |                           |______________xxx.png
   |
   |______________src
                               |
                               |______________xxx
                                                            |______________xxx.java

Then I can use

'new ImageIcon("res/fullscreen_16.png")'

under IDE and the icon shows in final build. However, if I build the .jar like this, and the problem still there. Double-click .jar and no icons at all. Any ideas?

Looks like your module setup is inconsistent to your jar structure.

Basically you should do the following (assuming the last mentioned directory structure):

1. Ensure that module dir ('xxxPackage') is not configured as a source root;
2. Ensure that source root dir ('xxxPackage/src') is configured as a source root;
3. Configure resources folder ('xxxPackage/res') as a source root;

Then you should check that your *.jar file contains files from 'xxxPackage/res' at the root entry and reference them by simple name like 'new ImageIcon("fullscreen_16.png")'
