Receiving AS2 MDNs - Mule 4

The following example shows how to use Anypoint Connector for AS2 (AS2 Connector) to receive AS2 MDN (Message Disposition Notification) messages from a trading partner and, for every received MDN, log a message that contains the message payload to the Studio console.

This example is similar to the Receiving AS2 Messages example, except that in this example:

You use the AS2 mdn listener source instead of the As 2 listener source and set the path to /receiveMDN.
On the Logger properties window, you set the Message field to MDN Received: #[payload].

The following screenshot shows the Anypoint Studio app flow for this example:

To test this example:

Run this app.

Run the app configured in the Sending Asynchronous AS2 MDNs example.

In the Studio console in this app, you should see a message for each received AS2 MDN that was sent asynchronously. For example:

INFO  2022-09-09 17:15:46,409 [[MuleRuntime].uber.06: [as2-basic-example].ReceiveAsyncMDN.CPU_LITE @1369de96] [processor:
ReceiveAsyncMDN/processors/0; event: 30609f70-307c-11ed-8f5a-38f9d3713331] org.mule.runtime.core.internal.processor.
LoggerMessageProcessor: MDN Received!

Run the app configured in the Sending Synchronous AS2 MDNs example.

In the Studio Console in this app, you should see a message for each received AS2 MDN that was sent synchronously. For example:

INFO  2022-09-09 17:15:46,409 [[MuleRuntime].uber.06: [as2-basic-example].ReceiveAsyncMDN.CPU_LITE @1369de96] [processor:
ReceiveAsyncMDN/processors/0; event: 30609f70-307c-11ed-8f5a-38f9d3713331] org.mule.runtime.core.internal.processor.
LoggerMessageProcessor: MDN Received!

If the Receipt delivery url field is not configured for the Send with Async MDN source and you are using an HTTP request, the header Receipt-Delivery-Option must be included with the As 2 mdn listener endpoint (http://localhost:8082/receiveMDN).
