The prjHL7Outbound project includes the following Connectivity Maps:
HL7 Outbound: A standard outbound HL7 messaging operation that receives the HL7 message from the JMS data queue, provides sequence numbering, sends the HL7 message to an external system, receives an acknowledgement from the external system, and writes the HL7 message and the ACK to a JMS Journal queue.
HL7 Forward Outbound: Outbound forward message mode is used with the delayed ACK. Its purpose is to get a message from a JMS queue and send it to an external system. No validation is performed.
HL7 Outbound Delayed ACK: Delayed Acknowledgement is similar to HL7Outbound, but the initial acknowledgement is received from the receiving system. After the sender receives the first ACK, it waits for a second ACK that indicates that the message was received by the external HL7 system.
