I am receiving IOException while trying to list directories in the remote SFTP server. I understand ErrorCode|Status=4 means
An error occurred, but no specific error code exists to describe the failure.
. Any ideas on what could be causing IOException while closing handle?
Here is the sftp console commands:
sftp usr@server.com
usr@server.com's password:
Connected to usr@server.com.
sftp> ls
dir1
sftp> cd dir1/dir2/
sftp> ls
file1.txt
file2.DAT
Exception received by my application:
Caused by: java.io.IOException:
