How to load icon from resource in Java?

Question

Possible duplication (solved): https://stackoverflow.com/a/1133132/783469

I have icons (jpg, png) for my application, which is stored in my directory /var/tmp/gameXbox/src/image/<here>. Now, How can i use them in application, without using hard link but as resource?

Example: not working

IconForMyButton = ImageIO.read(new File(
                    ClassLoader.getSystemResourceAsStream("image/button1.png")
                  ));

enter image description here

Works when i do with hard link:

IconForMyButton = ImageIO.read(new File(
                      "/var/tmp/gameXbox/src/image/button1.png"
                  ));

Make sure the images are contained in the classpath of your application, and use a relative link — Robin, Dec 28 '11 at 20:35
What you do want to load? An image from classpath or filesystem? This is a difference. You're mixing both up. — Michael-O, Dec 28 '11 at 20:57
@Google : Please do confirm first, You want to display this icon on your button, as your variable is suggesting. Am I right about that ? Regards — nIcE cOw, Dec 28 '11 at 21:04
@Michael-O: from classpath (filesystem is working for me, as above). — , Dec 28 '11 at 21:04

Resource loading takes place in the classpath, relative to the current package. If /var/tmp/gameXbox/src/ is in your classpath, then:

ImageIO.read( ClassLoader.getSystemResource( "image/button1.png" ) );

However, usually the src folder is not included in the classpath by IDEs. Try adding the image to the bin folder.

project/build/classes/image/* exist. But not working. See my edit above. – Dec 28 '11 at 20:53
I've edited my answer. I didn't even realize. You were trying to create a `File` object from an `InputStream` and I, from an `URL`. – Darkhogg Dec 28 '11 at 20:59
import javax.imageio.*; (to use ImageIO) – shieldgenerator7 Mar 12 '15 at 16:14

I usually use class.getResource for this kind of operation :

YourClass.class.getResource("image/button1.png")

i use it to retrieve the file from a jar archive but should work also to retrieve from filesystem resources.

Images do not go into a source folder but into a resource folder. Fix your IDE and use Maven and it will work with getResourceAsStream with the current context classloader.
