问题
I made a JavaFX application on Netbeans and I put this code for setting the icon to the window
primaryStage.getIcons().add(new Image("file:sicadcam.png"));
and when I run the project from Netbeans, it works ok: the icon appears on the window and in the taskbar. where I have to put the image.
When I clean and build the project, it generates two installers: one exe and one msi; and when I install the application and open it, the window doesn't have the icon sicadcam.png, it has the default java logo icon.
How or where can I set the path of the image so that when I install the application the icon appears.
回答1:
You should place the icon in your jar or classpath and then load it through a resource function.
E.g. if you place it to your bin folder, into the package where your class is, then the following should work:
primaryStage.getIcons().add(new Image(this.getClass().getResourceAsStream("sicadcam.png")));

I suspect that the image is not handled as a resource and not getting into your Jar file. Can you verify if it is there? (You can do that by Total Commander for example by pressing Ctrl+PgDown to go into the archive).
Another reason might be that NetBeans using a different run configuration and classpath. Where is your image? If it is in the package root (i.e., the folder which contains your top-level package), you can probably access it somehow like: ImageIO.read(getClass().getResourceAsStream("/sicadcam.png")).
Hope that helps something.
