OpenSSH Package and SFTP

I have an implemenation with one of the clients that uses the FTP over SSH ,
I downloaded the OpenSSH and successfully tested the scp command.
The issue is that I want the sftp to work from webmethods as a scheduled delivery batch service -similar to batchftp-.

The problem is that the sftp service in OpenSSH doesnt have an entry for the content that will be read from the queue tasks.

Any idea how to resolve this issue is appreciated.
