Restricting hidden files to upload

[Faseela Mohamed <fa...@gmail.com>]

Hi

Is there a way to restrict the hidden files to be uploaded in to the
folders.
Right now I am deleting the hidden file on onUploadStart and onUploadEnd
methods. It still upload the file and deletes. Is there an option to
restrict certain types of files. Any help is appreciated .. Thanks

    public FtpletResult onUploadStart(FtpSession session, FtpRequest
request)
            throws FtpException, IOException {
            System.out.println("User uploaded FtpServer");
        List< ? extends FtpFile > ftpFileList =
session.getFileSystemView().getWorkingDirectory().listFiles();
        for (FtpFile ftpFile :ftpFileList ){
            System.out.println(ftpFile.getName());
            if (defaultLogin.equals(session.getUser())) ftpFile.delete();
            if(ftpFile.isHidden()) {
                ftpFile.delete();
                return FtpletResult.SKIP;
            }
        }
        return super.onUploadStart(session, request);
    }

Or a "REFRESH " of session.getFileSystemView().getWorkingDirectory() will
be also helpful.

Thanks for the inputs ... To avoid even go to onUploadStart() , I used the
below method. ..


 else if ("STOR".equals(command)) {
            if (defaultLogin.equals(session.getUser()) ) return
FtpletResult.DISCONNECT;



*if (reqLine.contains("STOR .")){                System.out.println("User
upload HIDDEN FILE   ");                 return FtpletResult.SKIP;
    }*
            return onUploadStart(session, request);
        }

Sorry, didn't read the OP properly. I would agree with John. I do something similar in my code.

Do you want to forbid upload of hidden files?

I think if your onUploadStart() sends a `550 Permission Denied` response,
then returns SKIP, you'll achieve that goal. You would not need to delete
the file, as it would never get created.

You would need a different way to tell if the file is hidden than
File.isHidden() -- because you would not yet have a file. On UNIX, it's
just a filename starting with a dot.

I would look at overriding the NativeFtpFile.listFiles() method to achieve this. The filesystem is pluggable and comes with a native filesystem implementation by default; but you can implement your own and therefore obtain whatever functionality you need.
