Hi,

Is anybody aware of following error
Error: FTPClient.listNames(): unexpected 550 is encountered.

This is occuring in following process:
I have created a process where an input FTP adapter is picking up files and passing to receive->transform->invoke activities and invoke then invokes another output FTP adapter to ftp the transformed xml.
For input FTP adapter I am using a Native Transformation format of Fixed length file and for output adapter I am using a native transformation format where I have provided a xsd which is the edi definition xsd got from B2B

Here the BPEL process has been compiled and deployed successfully on the BPEL server. I am encountering the above error when file is placed in the input of file adapter but the file adapter does not pick up the file .At this point the state of process goes to off in BPEL console.

Is anyone aware what could be this issue and how to deal with this

Thanks
Sachin Sutar
