Invalid Message Channel - Enterprise Integration Patterns (original) (raw)

An application is using Messaging to receive Messages.

How can a messaging receiver gracefully handle receiving a message that makes no sense?

The receiver should move the improper message to an Invalid Message Channel, a special channel for messages that could not be processed by their receivers.

When designing a messaging system for applications to use, the administrator will need to define one or more _Invalid Message Channel_s for the applications to use.

The Invalid Message Channel will not be used for normal, successful communication, so its being cluttered with improper messages will not cause a problem. An error handler that wants to diagnose improper messages can use a receiver on the invalid channel to detect messages as they become available.
