This article is a follow on to the ?Oracle SOA Suite 11g HL7 Inbound Example?, at http://blogs.czapski.id.au/2010/06/o...nbound-example. In that article the B2B infrastructure was configured to return the ?immediate ack? as soon as it received each message. The ACK was always a positive ACK, regardless of whether the message was valid or not and whether it was successfully processed.

In this article I expand on the previous post by adding the Functional ACK, an explicit ACK message, which is returned after a message is parsed and validated, if validation is required. This means that rather than always returning an ACK the receiver will return a NAK if the message is invalid.
