ClassLoader in a virtual machine

Question

I have the source code:

private Image getImage(String path, ClassLoader loader) {
    InputStream image = null;
    try {
        image = loader.getResourceAsStream(path);
        return new Image(PlatformUI.getWorkbench().getDisplay(), image);
    } finally {
        if (image != null) {
            try {
                image.close();
            } 
            catch (IOException e) {
                //OK
            }
        }
    }
}

On my computer, this code works fine. But in a virtual machine:

loader.getResourceAsStream(path);

always returns null. Why?

EDIT:

The path is a relative path. For example: icons / tools / device.png. The application that I am developing contains more than ten projects. I am using the Eclipse IDE. All projects have the structure:

• com.pkg.name - folder with class icons
• with icons and other files

Jar files also have this structure.

Works fine on my computer applications. On a virtual machine (Windows Server (64-bit)), the application cannot load images from a Jar file.
