Images not loading after creating Jar

im wring a simple program and my images load in fine in the project but as soon as i export it into a jar file none of them load. i have little to no experiance creating artifacts or jar files.
project structure:
project:
src:
myclass1, myclass2...
res:
image1.png image2.png...
im using Toolkit.getdefaultToolkit to load in images
in my class i am loading the images in the constructor by writing
myImage = toolkit.getImage("res/image1.png");
this works perfectly fine in the project. does not work in the jar
i have also tried
myImage = toolKit.getImage("image1.png");
which does not work in the project or while opening the jar
i know toolkit is not the best way to go about loading images but i would like to know how i can fix this issue while using toolkit.
ive even tried using the absolute path to a folder on my desktop and once again they load in fine in my project but they do not get loaded when opening the jar. please help ive tried everything. thanks
(btw) if i open the jar file in intellij the images load but if i open the jar file in finder or from my desktop they do not. i want to be able to send the finished project to someone

The toolkit.createImage(String) method takes in a string, and interprets it as a path, looking for a file at that path. An entry in a jar file is not itself a file. It is therefore impossible to use this method to read image files that are in a jar.
However, that's not the only createImage method. There's also toolkit.createImage(URL) and that is the one you want.
SomeClass.class.getResource("something.png")
This expression works on any class (Foo.class gets you the class instance for Foo, and all class instances have the getResource method), and will look for the named entry in the exact same place SomeClass.class (the file) lives. If SomeClass.class currently lives in a jar file, then that's where it'll look.
Thus, ensure that img.png is in the same place your class file is (ensure it is jarred along with the rest), and that will work. You can also ask for e.g. SomeClass.class.getResource("/foo/bar/img.png"); this will then look from the 'root' of where SomeClass is. So if you have a jar such that if you run jar tvf thatjar.jar and you get:
....
/com/foo/yourpackage/SomeClass.class
....
/foo/bar/img.png
then /foo/bar/img.png works.
thus: Once you know where you put that stuff in your jar file:
toolkit.createImage(YourClass.class.getResource("image1.png"))
is what you're looking for.

images not showing up when running JAR

I've spend 5 hours already and have no idea why images are not loaded when running Jar.
Project structure:
Blackjack_Game
- Source Packages
- Images
- blackjack
.... classes...
At project properties I have src - Source Packages folder added by default. Tried to put images directly into the project's folder and removing /Images/, but still no help.
Inside the code I have:
dealer_url = getClass().getResource("/Images/4_of_hearts.jpg");
File img = new File(dealerCardGenerator.dealer_url.getPath());
BufferedImage bufferedImage = ImageIO.read(img);
dealerCardGenerator.imageIcon = new ImageIcon(bufferedImage);
So inside NetBeans IDE everything is OK. Fully working. But after built&clean I see no images, but all actions are done.
Can you please suggest what is wrong? Getting so mad because of this ((((

A jar entry is not a file. java.io.File can only identify a file, not a jar entry. java.net.URL however can identify a jar entry using the jar: scheme, or a file using the file: scheme. That's why Class.getResource() returns a URL not a File.
Two solutions:
use the URL: ImageIO.read(getClass().getResource("whatever"))
ImageIO can also use an already-opened stream, which classloader can provide:
ImageIO.read(getClass().getResourceAsStream("whatever"))
Duplicate of at least #2-4 of the questions autosuggested as related:
Including Images with an executable jar
Loading images in a jar
Getting images from a .jar file

Thank you all for clarifying the problem. I've realized why some functions were not working.
So the solution is to replace URL with ImageIcon:
ImageIcon i2 = new javax.swing.ImageIcon(getClass().getResource("whatever"));
and then just set icon as label icon:
jLabel1.setIcon(i2);
In this way JAR works. Previously, all methods after this icon set operation were not working, as the program was actually stopped, now everything works fine.

Which is the right way to link images and export in Eclipse (Java)?

The problem I'm having right now has to do with how images are linked when exporting the jar. Right now, my program runs on eclipse and the images do work, but when I try to run it from the exported file, the screen goes white. I have the images in a src/res folder and they appear inside the jar just free in the root directory. the code which I use to link the images is this one:
img = ImageIO.read(Thread.currentThread().getContextClassLoader().getResourceAsStream(
"\\bkg.png"));
My question is, how should I write the path so I can export the jar and get the images to work? Or which line of code should I use to make it work?
Thanks in advance,

Use this :
img = ImageIO.read(MyClass.class.getResourceAsStream(path));
Doing this, you have to know that path is a local path starting from the package of MyClass.

JavaFX loading images from CSS in Webstart

I currently have a major problem with loading of CSS and images in JavaFX.
The goal is to make JavaFX load the images that are defined in the CSS file. I get this to work easily in the IDE and in the standalone execution. But once I try the the application as a applet and run it inside a browser context everything fails.
The CSS file is still load properly, but the image files remain blank. Sadly I can't find a way to make JavaFX log why the image loading is failing. All the images are located in subdirectories from the location of the CSS file and are accessed for example like this:
.button-gray {
-fx-border-image-source: url("button/buttongray.png");
}
The CSS file is located in the same package as the class that handles loading it and is load like this:
final URL css = Util.class.getResource("sheet.css");
if (css != null) {
parent.getStylesheets().add(css.toExternalForm());
}
I tried already placing the resources in the root directory and load it with Util.class.getClassLoader.getResource(...) and Thread.currentThread().getContextClassLoader.getResource(...). Both worked fine in case the application was executed as stand alone. Neither worked in case the application is launched from a webstart applet context.
But as I said. In all cases there is no indication that the CSS is not load. The styles defined in the stylesheet are applied properly with exception of the images.
I am running out of idea what the reason for this is. I package and publish the application using the gradle javafx plugin by shemnon.
Building environment:
Oracle Java 1.7b45 x64
Gradle 1.9
Anyone know how to fix this problem or has any idea how to debug it.
Sadly the logging facilities of JavaFX (even the CSS Logger) and the applet trace console give no indication what the problem is.
New Information!
The JNLP file is located here:
JNLP-File
How ever, this file is not the problem. The problems seems to be the generation of the binary css file that is part of the deployment process of JavaFX for webstart. In this binary file, for some yet unknown reason there is a reference to the CSS file inside by building environment. This causes the CSS loader to load the image files from the location on my building server. Something that does not work in my local computer. Builds I did on my local computer on the other hand work because the files are still at the location its looking for.
So now the problem seems to be limited to the binary css generation that stores a entirely wrong file reference.

1) Can you post the .jnlp file that you're using to deploy the app? An incorrect .jnlp can cause resource loading issues like this.
2) Give us the exact invocation of Thread.currentThread().getContextCLassLoader.getResource("") that you're using.
3) Report the contents of the .jar file, with the exact folder/path structure of the file(s) in the jar that you need to load. For example, 'My code is looking for example.png, it should be in the pics.jar file inside the folder com/mycompany/myimages', something like that.
WebStart takes some doing to get working, but I'd suspect the answer lies in there somewhere. If all else fails, I've found JaNeLa to be helpful in debugging web start deployment problems. http://pscode.org/janela/

Have you tried loading the css file with:
final String css = getClass.getResource("sheet.css").toExternalForm();
parent.getStylesheets.add(css); // taken that parent is the name for the Scene.
For the css:
-fx-border-image-source: url("../button/buttongray.png");
Using URL and Util.class is not something that is common to use for loading stylesheets afaik.
Maybe try NetBeans IDE 7.4. Personally i don't know Gradle.

Error loading images in Signed Jar, JNLP Application

I am developing JNLP Application and using maven-webstart plugin to create JNLP. When running the application in my local, it works correctly but when I run in Tomcat Server using jnlp, it does not load images and also does not give any exception.
I am loading images as below
new ImageIcon(getClass().getResource("/icons/save.png"))
What is wrong with my code?

Where are your icons located? How do you run a jnlp application inside tomcat? Assuming you don't have a lot of images, you can package them inside one of your packages. Just create a package called com.yourproject.resources and dump some images there. Then the way to access them would be:
//define it in some class
public URL obtainImageResource ( String nameOfResource )
{
return getClass().getResource( "/com/yourproject/resources/" + nameOfResource );
}
Do get them with a URL.
Then to create the stuff you need:
BufferedImage yourImage = ImageIO.read( yourclaass.obtainImageResource( "yourimagepng.png" ).openStream() );
Note some things: In my setup you need to package your images into your jar.

It's hard to say without more information. You might use jar -tf to see if the images are in the JAR file. In the meantime, here's a working JWS application that loads images, for reference.
