directory listing on remote folder returns empty

Question

Hi,

I am using edtFTPj-free (ver 2.0.0) and JDK 1.4.2_08 to connect to an FTP server to upload files.

The FTP Server and system details are as below (as obtained from Windows FTP client):

ftp> open zosnq
Connected to zosnq.myplace.com.
220-IPFTPD1 IBM FTP CS V1R8 at ZOSNQ, 14:31:27 on 2008-01-24.
220 Connection will close if idle for more than 5 minutes.
User (zosnq.myplace.com:(none)): guest1
331 Send password please.
Password:
230 GUEST1 is logged on.  Working directory is "GUEST1.".
ftp> QUOTE SYST
215 MVS is the operating system of this server. FTP Server is running on z/OS.
ftp> pwd
257 "'GUEST1.'" is working directory.

I used the LS command to see if there are any files in the working directory.
One file was found to be there.

ftp> ls 'rxt.ibt.*'
200 Port request OK.
125 List started OK
'RXT.IBT.TEST.B00001.D0000001.ZIP.OUT'
250 List completed successfully.
ftp: 40 bytes received in 0.00Seconds 40000.00Kbytes/sec

I tried to use FileTransferClient class from EDT API to get the list of files in the working folder.
Both

fileTransferClient.directoryNameList();

and

fileTransferClient.directoryList();

return empty.

Questions:
1. Is MVS an unsupported OS? Does not EDT API support FTP servers on z/OS?
2. Do you intend to have an MVSParser to support this kind of a system?
3. If there is no current support, is there a recommendation as to how to develop a custom parser by the end-user-developer?

Any help towards answering these questions is greatly appreciated.

Thanks.

Answer 1

directoryNameList() should work ... can you post the DEBUG log?

Answer 2

Thanks for the prompt response.

I executed the following statements and got the DEBUG log.

String[] files = ftpClient.directoryNameList();
//Check the array

FTPFile[] ftpFiles = ftpClient.directoryList();
//Check the array

String result = ftpClient.executeCommand("LIST 'rxt.ibt.*'");
//print result

result = ftpClient.executeCommand("NLST 'rxt.ibt.*'");
//print result

The DEBUG log has been pasted below:

You could see that I had executed the LIST and NLST commands thru fileTransferclient and the results that I got was as below:
LIST -> Result: List started OK
NLST -> Result: List completed successfully.

Thanks.

Answer 3

Try directoryNameList(".") and directoryList(".", true)

If that doesn't work use "rxt.ibt.*" as the arg

Answer 4

Thanks again for the quick response.

String[] filesStrArray = ftpClient.directoryNameList("'rxt.ibt.*'", false);

made it work.
