Making SFTP outbound gate way pollable for mput operation

Question

I am using spring integration for SFTP operation. I need to poll the files with directory structure from a certain location of SFTP and also put files with directory structure from local directory to certain SFTP location. I have added faking inbound channel adapter fro mget & mput opeation. While running Junit , some junk message files are generated in target SFTP location of mput operation. And ,after war is deployed no file is getting transferred to mget local directory. The mput and mget operation will started once war is deployed in server Please advice the configuration. This queston is in refrence to SFTP inbound adapter configuration for multiple remote directory using single adapter and single channel

Answer 1

It is not at all clear what you are asking. Phrases like "some junk" are useless. You should be able to debug this application by turning on DEBUG logging and track the messages through the flow.

Answer 2

MPUT is end-user operation. What is the reason of inbound-channel-adapter for such an operation? You should send local directory as a message payload to PUT all files to the SFTP. Right now your config does not make sence.
