Error when using File protocol

Question

Hi,
I have set up ACME (Host) and Vision (TP) to send an xml file using "Custom Document over Generic Exchange". I post a file to the inbound queue using the tutorial shell script. The file shows up in the /tmp/b2b directory that I set up. However, it gets deleted in about a minute.
The transactions shows as completed under "Business Message Status Report" The error report shows: "Document protocol identification error."
The debug log shows the following:
<Exception xmlns="http://integration.oracle.com/B2B/Exception" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<correlationId>null</correlationId>
<b2bMessageId>0A0428AA10EA56E70720000017C970F0</b2bMessageId>
<errorCode>AIP-50083</errorCode>
<errorText>Document protocol identification error</errorText>
<errorDescription>
<![CDATA[Unable to identify the document protocol of the message  ]]>
</errorDescription>
<errorSeverity>2</errorSeverity>
The ack mode is set to none. Why is the iB2B trying to read the message after writing to the output directory?
Thanks in advance.

Hi
This could be due to the fact that you have used the same endpoint for Vision and Acme.
The flow seems to be as follows
- Enqueue message into Queue
- Acme B2B picks up the message, finds the message is for Vision and drops it into the endpoint defined for Vision (endpoint taken from the Delivery Channel created for TP Vision). Till this it seems as expected.
- Acme B2B polls on the endpoint for it to receive the message ( this is endpoint taken from the Delivery Channel created for Host Acme).
- If there is a file in the endpoint directory, it will be picked by Acme B2B.
I feel you have the same endpoint given for both Acme and Vision. Please try the following
- Change the Vision endpoint to /tmp/vision
- If the endpoint had been used as "use exsiting" then even the Acme endpoint would have changed to "/tmp/vision", so please create a new Delivery Channel for Acme and set this endpoint to "/tmp/Acme".
Hope this helps.
