Physical Transmission Wrappers
There are two physical transmission wrappers, which provide mappings between real world inputs(such as MQ, HTTP, File, and so on) and the core physical transmission flow.
The wrappers are used to:
- Manage channel identification
- Manage and log failed messages
- Provide a deployment point for inbound mappers
The following figure shows the physical transmission wrapper for the inbound MT103 message for the Store and Release sample application.
