I use this function to detect if my file exists or not. While I have some image stored as .jpg, .JPG, .png, and .PNG. But it always return .jpg or .png as true even if the real file has extension .JPG or .PNG.

After I render it to my webpage it throw an error "Failed to load resource: the server responded with a status of 404 (Not Found)".

public static String getPhotoFileExtension(int empKey){
    try{
        String[] types = {".jpg",".JPG",".png", ".PNG"};
        for(String t : types)
        {
            String path = "/"+Common.PHOTO_PATH + empKey + t;
            File f = new File(Sessions.getCurrent().getWebApp()
                    .getRealPath(path));
            if(f.isFile()) 
                return t;
        }
    }catch (Exception e) {
        e.printStackTrace();
    }
    return "";
}
