The prjHL7Inbound project includes the following Connectivity Maps, both of which use the same Collaboration:
HL7 Inbound: A standard inbound HL7 messaging operation that receives the HL7 messages from an external system, sends an acknowledgement of the message, provides sequence numbering, writes the HL7 message to a JMS data queue, and also writes the HL7 message and ACK to a JMS Journal queue.
HL7 Forward Message Inbound: Inbound forward message mode is used with the outbound delayed ACK. Its purpose is to get a message from an outbound forwarder and return an acknowledgement.
