FTPClient.storeFile transfers zero bytes
----------------------------------------
Key: NET-411
URL: https://issues.apache.org/jira/browse/NET-411
Project: Commons Net
Issue Type: Bug
Components: FTP
Affects Versions: 3.0
Environment: Java 6, it behaves the same way on Windows and on Solaris.
Reporter: Jaroslav Chmurny
When I try to upload a file to an FTP server via
org.apache.commons.net.ftp.FTPClient.storeFile(String, ImputStream), everything
seems to work well. The method returns true, the reply string seems to be OK, I
also see in the FTP server that there was a successful transfer. However, zero
bytes are transfered, although the ByteArrayInputStream used as the second
argument has some data (some hundreds of bytes). When I capture the network
traffic with Wireshark, I also see that everything seems to be OK, but the data
connection actually transfers no data. Immediately after the TCP handshake, the
client closes the connection with FIN. I tried to use a CopyStreamListener to
see what's going on - it reports successful transfer of the expected number of
bytes. When I perform the same test with Commons Net 2.2 instead of Commons Net
3.0, it works properly - my data gets uploaded, and I get the same OK responses
as with 3.0. When switching between 2.2 and 3.0, I do not compile anything
.
