How to link a soap request and response in mule 3 - file

Question

I need to send a file to a external web service. When the response is 1, the file should be deleted, else the file should be kept.
I use the file connector to send the file, and insert a record into Oracle. When the file is sent out, the key is the message id of the file connect. I want to keep the message id so that I can update the record using this id when the response is back.
I tried to use MessagePropertiesTransformer to add a custom property, but the response doesn't preserve it. Is there any way to keep the message id?
My config:

When I copy the file one by one, it's ok, but when I copy more than five files to the directory, some records can't be updated.

Answer 1

Set your JDBC outbound endpoint to request-response in order to ensure the flow will execute in a single thread. With your current configuration, the 2 in-only JDBC requests are "detached" from the flow and executed in parallel from it.
