Why am I getting a resource not found ?

I have a class that has the code:

Code:

---

        final TrayIcon trayIcon =
                new TrayIcon(createImage("c://aa.jpg", "tray icon"));

---

I definetly have a file called aa.jpg in c:\ ( I am using Windows )

When I try running my code I get:

Resource not found: c://aa.jpg
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: creating TrayIcon with null Image
at java.awt.TrayIcon.<init>(Unknown Source)
at TrayIconDemo.createAndShowGUI(TrayIconDemo.java:76 )
at TrayIconDemo.access$0(TrayIconDemo.java:68)
at TrayIconDemo$1.run(TrayIconDemo.java:63)

I have also tried with c:\\aa.jpg , did not help.

Thank you.

Where is aa.jpg located? What does your createImage(...) method look like?

aa.jpg is located at c:\aa.jpg

Code:

---

    protected static Image createImage(String path, String description) {
        URL imageURL = TrayIconDemo.class.getResource(path);
       
        if (imageURL == null) {
            System.err.println("Resource not found: " + path);
            return null;
        } else {
            return (new ImageIcon(imageURL, description)).getImage();
        }
    }

It appears that you're getting the image as a resource when you should be getting it as a file.

Thanks, I will just skip this for now.. A bit advanced for me.

The getResouce() mehod uses the classpath to find resources. You are giving it an absolute file path, not a path that is relative to the classpath.
Try moving the image to a folder on the classpath and changing the the path variable to use the relative path.

Thanks Norm.

You can also specify a file resource; the URL would look like this: "file:///aa.jpg".

kind regards,

Jos

Thanks, I will try both.
