Answer 1

Here's how you can do it without JNA.

public void setWallpaper(File file)
throws Exception {
    String as[] = {
            "osascript", 
            "-e", "tell application \"Finder\"", 
            "-e", "set desktop picture to POSIX file \"" + file.getAbsolutePath() + "\"",
            "-e", "end tell"
    };
    Runtime runtime = Runtime.getRuntime();
    Process process;
    process = runtime.exec(as);
}
