如何使用Java / FTP在Windows上下载/打开PDF文件？

Question

I am trying to download and open a PDF file from the server using the below code and the org.apache.commons.net.ftp.FTP client, but it doesn't work on Windows 8. It creates the pdf in a folder but it creates a corrupted file. It works fine on the Mac. Any ideas what I can do in order fix this? Thanks

   private static void openFileFTP(String fileName) throws  FileNotFoundException, 
   IOException {

    ftpClient = new FTPClient();
        if (checkConnection()) {

            //Set the type of file to be displayed
            ftpClient.setFileType(FTP.BINARY_FILE_TYPE);

            FileOutputStream outPutFile = new FileOutputStream(fileName);
            ftpClient.retrieveFile(serverDirectory + fileName, outPutFile);

            File file = new File(fileName);

            try {
                Desktop.getDesktop().open(file);
            } catch (IOException ioe) {
                System.out.println(ioe + "error here");
            }
        }
}
