I am sorry if this is a stupid questions, but I am having issues with
commons-net corrupting downloaded .zip files. Here is my setup:
Client:
Ubuntu 10.04 64bit
java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)
I am using commons-net-2.0
All I am trying to do is connect to a ftp server and download a .zip
file. I have tried from two different ftp servers including a netware
6.5 and an Ubuntu 8.04 LTS server and they both corrupt the file.
The application runs and all looks well until I do a md5sum on the
file.
I get:
3c8d305a4e30592f0ac89fd1f2ce7556 Known Good file
50855164b0b0224521e930d8324742d3 Downloaded File
2591697 Known Good file
2591639 Downloaded File
On our netware server I tried setting:
FTPClientConfig conf = new
FTPClientConfig(FTPClientConfig.SYST_NETWARE);
ftp.configure(conf);
But it didn't seem to make a difference.
Any help would be greatly appreciated.
here is my code
