Re: [HAPI-devel] HAPI TestPanel rejects message

[Tom W. <tw...@su...>]

Hi. I am trying to implement enhanced ACK mode with HAPI and encountered the same problem described here:

https://www.mail-archive.com/hl7api-devel%40lists.sourceforge.net/msg01398.html

I am testing a system which receives ORU messages, does some processing, and sends an asynchronous ACK (enhanced mode) back to the sending system.

Two things I want to accomplish:


1)      Implement a HAPI server which will receive ORU messages, and optionally return an accept ACK. It appears that it is not possible to omit the accept ACK. How do I implement the processMessage method to not send an accept ACK? If I simply return null, HAPI throws an exception and returns its own NACK:
MSH|^~\&|||||20140304142506.948-0800||ACK^R01^ACK|502|D|2.5.1
MSA|AE|2013101516464300008
ERR|||207^Application internal error^HL70357^^^^^^Message may not be null|E

2)      For testing purposes I have several "dummy" HAPI servers which:

a.       Send HL7 ORU messages and receive ACKs asynchronously

b.      Receive HL7 ORU messages and send ACKs synchronously

c.       Print everything to stdout


I don't care so much about data integrity (this is checked manually during testing). In fact, it would be easier if I had one HAPI server that receives ACKs and prints them to stdout without caring if the message control ID matches a previously sent message.

So is enhanced ACK mode supported? And how would that work?

Thanks in advance,
