I am using url-open to ftp an incoming base-64 encoded pdf file to drop into an external ftp server.

The ftp process works fine.

Now I want to add some reliability to the process by handling errors and taking corrective actions in case of failures. Datapower documentation on url-open  mentions the use of response="xml" attribute to get the response attributes from url-open. Somehow, the ftp server that I am using is sending an empty response for the url-open, although the file transfer is successul.

How do we make sure we get a response? Can we atleast get an error code from the ftp server? I checked the global and local variables after the ftp, but didnt find anything that would help.

Any help would be appreciated. Thanks!!!

Here is the log.

The value of ftpComamnd is in the format

ftp://user:password@host:21/

your response is set to ignore. does it work like that? I think what you are looking for is setting your response to responsecode... from the manual

When the response attribute is set to responsecode, all successful FTP transactions
return the following element:
<url-open/>
When the response attribute is set to responsecode, all failed FTP transactions return
the following element:
<url-open>
<statuscode>n</statuscode>
</url-open>

Now i am getting the xml shown below as the response.
It actually throws an error message indicating that it cannot parse the response. How do we get success/failure codes...like a 200 if it is successful or something else if its a failure. Like for this one, I have no way of knowing if the file made it to the ftp server.



<?xml version="1.0" encoding="UTF-8"?>
<FTP xmlns:date="http://exslt.org/dates-and-times" xmlns:soap="http://schemas.xm
lsoap.org/soap/envelope/"><RESPONSE><url-open><errorcode>196609</errorcode><erro
rstring>Incomplete markup or missing document element at offset 0 of ftp://user:password@host:21/</errorstring><
/url-open></RESPONSE></FTP>

Actually i tried using response="responsecode-ignore" which is equivalent to the option you gave...
So now, if there is nothing, it wouldnt try to parse.
But we still have the problem of getting a success code "200" from the ftp server.

After changing it to response="responsecode-ignore" i also tried to give an incorrect host name, and it came back with

<?xml version="1.0" encoding="UTF-8"?>
<FTP xmlns:date="http://exslt.org/dates-and-times" xmlns:soap="http://schemas.xm
lsoap.org/soap/envelope/"><RESPONSE><url-open><statuscode>6</statuscode></url-op
en></RESPONSE></FTP>

I have no idea, what 6 means in terms of status code.
If there is a list somewhere about these codes returned from url-open, life would be easy.

Appreciate your help in getting this resolved.

I have created a PMR with IBM on this issue and have asked them to provide an index of these status codes. Appreciate all your help with this.

Will do. Thanks.
