Unable to determine if file 'xxx' exists

Question

Hello,
I use edtftpj-1.5.4.jar inside java project.
When i try to put a file to a remote host,
i get the following exception when i check if file exists :

com.enterprisedt.net.ftp.FTPException: Unable to determine if file 'xxx' exists.

The error line is : boolean existfile=ftpclient.exists('xxx');

I made a little search in the forum and found :

http://www.enterprisedt.com/forums/view ... rmine+file

I applied the patch with no success.

Is someone have a solution ?

Thanks a lot.

Answer 1

Please call FTPClient.getLastReply() immediately after calling FTPClient.exists() to obtain the response-code and message returned when the test for the file was performed, and then post these to the forums so that we can see what server is telling us.

That reply is not at all what I expected. The final FTP command that is sent before the exception is thrown is "RETR", so it's strange if you get a "250 CWD command successful" response since this appears to be a response to a "CWD" command. Is it possible for you to link the edtFTPj source into your code and a modification?

If so, please change the last three lines in the FTPClient.exists(String) method from:

String msg = "Unable to determine if file '" + remoteFile + "' exists.";
log.warn(msg);
throw new FTPException(msg);

to

String msg = "Unable to determine if file '" + remoteFile + "' exists: "
   + lastReply.getReplyCode() + " " + lastReply.getReplyText();
log.warn(msg);
throw new FTPException(msg);

and then post the output.
