Inbound HL7 V2 Collaboration - Part 3
After the ACK is sent, the HL7 V2 message and the ACK are journaled to the JMS queue Journal
destination. If the message fails to journal, the associated recourse action is taken.
If sequence numbering is enabled, the processAckNakSequenceNumbering method calculates
the next sequence number and stores the number in the sequence number file by calling the
updateSequenceNumberFile
method to persist the next sequence number.
Outbound HL7 V2 Collaboration Overview
The outbound HL7 V2 Collaboration, jcdHL7Outbound, contains Message Libraries for the
HL7 Resource Adapter, JMS Data, HL7 ACK, JMS Journal, and JMS Error, as well as the
Generic HL7 Event. The Collaboration works with its own internal code and the properties
configuration files. The outbound Collaboration assumes that it is reading valid HL7 V2
messages, so the data flow that feeds this Collaboration must ensure this.
