How to append binary data to existing file in OSB

Question

Hi,
I have an OSB project that I need for it to append binary data via ftp.  Here's my current flow:
MFL binary output --> Replace $body with mfl binary output --> Publish to action (Business service that's configured to ftp binary data).
However, when the data is ftp'ed the following error is thrown:
URI = ftp://xxx:21/opt/home/zzz/logs
Request metadata =
    <xml-fragment>
      <tran:headers xsi:type="ftp:FtpRequestHeaders" xmlns:ftp="http://www.bea.com/wli/sb/transports/ftp" xmlns:tran="http://www.bea.com/wli/sb/transports" xmlns:xsi="h
ttp://www.w3.org/2001/XMLSchema-instance">
        <ftp:fileName>11802_insert_oh_xfrmr.eai_data</ftp:fileName>
      </tran:headers>
      <tran:encoding xmlns:tran="http://www.bea.com/wli/sb/transports">utf-8</tran:encoding>
      <ftp:isFilePath xmlns:ftp="http://www.bea.com/wli/sb/transports/ftp">false</ftp:isFilePath>
    </xml-fragment>

From what I understand the error code 553 represents a bad file name.  The file name that I'm supplying is 11802_insert_oh_xfrmr.eai_data but it appears that the name is changed to 11802_insert_oh_xfrmr.eai_data.a .  So I did the obvious and changed the file several different ways (without the .eai_data extension, removed the numbers from the file name) but still no luck. 
Any suggestions?
Thanks,
Yusuf

Answer 1

Thanks Eric.
I'm using the JCA FTP adapter instead and noticed it's appending the test generated data supplied by the OSB test console.
However, how can I ensure that the MFL output that I need to append will be placed on a new line? 
Also, how should I map/assign the MFL binary output to the opaqueElement type base64Binary defined in the WSDL file below?
Once again here's a sample payload that I need to ensure will be presented on a new line:

Here's the WSDL file that gets generated for the FTP adapter:
