Question

How do you append to a file when using FTP as the destination node?

Answer 1

It looks like there is an option within camel FTP, which QIE uses (see http://camel.apache.org/file2.html).

Try adding the following Custom Apache Camel parameter:

fileExist=Append

See the following example:

 

I am unsure of the performance of this option.  If performance becomes an issue, I recommend appending to the file locally, and then uploading the file with a separate channel at a certain interval.

When using this method it seems to concatenate the last segment of message one with the first segment of message 2 without a carriage return. Is there any additional code that can be added to address this?

You will need to append the carriage returns to your message content before you send it. Depending on your message type depends on what you need to do. Most likely you need to convert to a plain text message and append \r to the front of your message.

message = qie.createTextMessage('\r\r' + message.getNode('/'));
