Symptoms

While using an SFTP_JAVA job to connectto a remote SFTP server to put a file empty directory, the job fails with a 'Nosuch file'  or 'File not found' errormessage being displayed in the job output file and the file is not transferred.

---

Cause

We have seen instances where theremote third party that manages the remote server deletes files from the remotedirectory when it meets some criteria to automatically clean their system orwhere a directory is empty. If theremote directory is empty, the SFTP_JAVA job will fail.

---

Workaround

1) Request that thethird party vendor leave a file in the directory so that the directory is neverempty.

2) In some casesupdating the third party utility (jcraft) that we use for the SFTP_JAVA job sothat it uses a more recent jar file enables you to transfer a file to an emptydirectory on the remote SFTP server. 

We shipwith jsch-0.1.39.jar file and that file is used for our SFTP_JAVA job. If you would like to update that file, pleasefollow the steps outlined below.

Download the newer file at:

http://www.jcraft.com/jsch/

Scroll down to the Downloadsection download the jsch-0.1.51.jar. Movethe current jsch-0.1.39.jar file to $AW_HOME and place the newer file(jsch-0.1.51.jar) in the $AW_HOME/web/classes directory. Then re-run the failedSFTP_JAVA job.
