I am trying to pull a pdf file from a directory, then send the base64 message in a json to a webservice, then utilize the response from the webservice call and the original message data to create a new XML message to send to a different location most likely utilizing multiple channels. Since a binary directory source node cannot be set to wait for a response, even though I set to wait for an ACK on the destination, I get an error, though I'm getting a response. I need to use the response and the original file information from the source to do this. Thoughts?
