change the icon of .jar file
posted 12 years ago
I have created a executable test.jar. The icon of test.jar is platform dependent and apperas to be default icon.
I would like to add my own icon to test.jar.

Unlike an EXE file, a JAR file has no icon. It’s the operating system* that gives it an icon. You cannot change the icon of one JAR file without changing the icon of all JAR files. You should consider using a shortcut, but that’s not platform independent.
* Actually the window manager, but let’s not go into details. It’s not the JAR file itself.

Hey akki. I don’t think you can set this with some jar file attribute, but you can modify the icon depending the operating system.
In Ubuntu, right click -> properties -> in the basic tab, click on the picture, then select your icon.
This is not a nice solution, because you would need to do this in all clients.

you can change the icon of the jar file by the below code:
what i have done here is, I have saved the image ‘mylogo.png’ in a folder named ‘images’. Then i am making it as the icon of the jar file.
To make the clients to see your icon, Made that image folder as hidden folder and send that hidden folder along with zip file in which you will place your jar application and lib files.

JavaFX Application Icon Setup
All programs require a nice-looking icon or logo on the taskbar and the window to make it look professional. JavaFX provides easy ways to set up an application icon using any image of your choice, whether it be JPG or PNG or something else. In this tutorial, let’s see how to set up an icon for the application
Set JavaFX Window/Stage icon from an image file
The usual method of attaching an icon to the JavaFX application is that, you simply include the icon image inside the JAR file as a resource and then use it. Let’s see how you can do that.
Step 1: Add the icon to the resource directory
First, add the image into the resource directory. You can use any supported image formats, like PNG, JPEG etc.
Step 2: Attach the icon to the application window
Now, let’s attach the image from the resource directory to the window, aka stage. The following code snippets show how to do that in an example program.
import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.image.Image; import javafx.scene.layout.StackPane; import javafx.stage.Stage; public class JavaFXIconExample extends Application < @Override public void start(Stage stage) < Scene scene = new Scene(new StackPane(), 320, 320); //Attach the icon to the stage/window stage.getIcons().add(new Image(JavaFXIconExample.class.getResourceAsStream("/logo.png"))); stage.setTitle("Sample program!"); stage.setScene(scene); stage.show(); >public static void main(String[] args) < launch(); >> So in the above example, we are attaching the icon to the primary stage (also known as root stage). If you want to add logo to the other stages you create, you can repeat the same process again to add icons to them as well, with just one line of code.
stage.getIcons().add(new Image(JavaFXIconExample.class.getResourceAsStream("/logo.png"))); 
Set icon from an image URL
Now, let’s say you want to add the image dynamically from a URL instead of adding from an image file, that is also easily possible. This can be done with just one line of code, as shown below.
stage.getIcons().add(new Image("https://genuinecoder.com/wp-content/uploads/2022/06/genuine_coder-3.png")); In this example, I have used genuine coder logo to dynamically load the application icon. The advantage of using the logo from a URL is that, you can change the logo in the server without touching your program once it is rolled out to your customers.
Conclusion
JavaFX provides a one-line option to attach images/logo to the windows. The logo image can be loaded from an image file or from a URL.
