Symptoms

The FTP server is running on SUSE Linux, and all configuration is default  and  you configured the SFTP Adapter according the the following link:

Oracle� Application Server Adapters for Files, FTP, Databases, and Enterprise Messaging User's Guide
10g Release 3 (10.1.3.1.0)
Part Number B28994-02

2.4 Using SFTP with the FTP Adapter

Using SSH  to connect the server is fine. And in command line, using the following commands to login , read and write files works fine:

$ sftp <username>@<hostname>

However, at run time, you still get the following error  messages:
