Exception Subprocess mechanism in SAP CPI

[former_member736500]

Hi Experts,

I am working on a CPI Iflow in which I need to log the original message(headers+body) using exception subprocess whenever the message execution is failed. To achieve this, I have maintained exception subprocess with SFTP channel to post the failed message into the SFTP server. While executing the flow, I am getting below error.

Error Details:

org.apache.camel.component.file.GenericFileOperationFailedException: Cannot write null body to file:

As per my observation:

• only error details are sent to the ‘Exception Subprocess’ to catch and not the actual message(headers+body).

• The actual message(header+body) is not sent to the exception subprocess.

Queries:

• Is my understanding accurate?

• If so, is this behavior documented somewhere?

• What is the best practice to transfer the actual message(headers+body) using exception Subprocess?

Thanks.

Hi Kumar,

I scanned the contents of Bhalchandra's patterns but I can't find anything on this topic. I don't think this approach is documentented seperatly.
