Hi Eugene,
Re. multiple errors:
The HL7 "ACK" message type actually allows you to specify the details of
more than one error in your response, using the repeatable ERR segment. The
*generateAck(String, HL7Exception)* method only populates the first one,
since this is a common use case, but there is nothing stopping you from
grabbing multiple reps and populating each one with the details.
E.g.
firstException.populate(ackMessage.getERR(0), null);
secondException.populate(ackMessage.getERR(1), null);
// etc....
Really, we should probably have a varargs (HL7Exception...) version of the
generateAck method. I've filed an enhancement request to that effect. I
think it would make sense..
Re. non-HL7 errors:
This is generally handled by using specific acknowledgement codes. I don't
have HL7 chapter 2 handy right now, so I'll paraphrase a bit, but this is
how the ACK code is generally used:
AA - Message was successfully processed
AR - Message was not successful because of an issue with the message (bad
contents, etc.)
AE - Message was not successful because of an issue with the server
(unexplained exceptions, IO errors, etc.)
This is only a guideline though. Every sending system will have it's own
interpretation of how these ack codes should be interpreted, so in the end
your best bet is to be flexible and let things be configured by specific
implementations.
Cheers,
James
