If you look at the MSH-8 (ADT^A08), there is no message structure component
(3rd component of field). Therefore PipeParser looks up into
ca.uhn.hl7v2.parser.eventmap.2.3.1.properties for appropriate message structure
for ADT A08 event. There is mapping ADT_A08 => ADT_A01. That's why you get
instance of ADT_A01 message. It's OK, you'll get all fields from your message.
If you like to get instance of ADT_A08 class, then your MSH should be like this:
MSH|^~\\&|RAMSOFT|SENDING FACILITY|RAMSOFT|RECEIVING
FACILITY|20101223202939-0400||ADT^A08^ADT_A08|101|P|2.3.1

Subject: Re: [HAPI-devel] This Parser and Library are Great! Quick (hopefully)
Question Though!
To that would suggest that your code may be reading a different message. The
one you provided looked like a valid A08 to me, so presumably it would parse as
such.
Perhaps try:
Message msg = .... (however you are parsing)
System.out.println(msg.encode().replace('\r', '\n');
Just to see if the message actually matches the one you are expecting.
Cheers,
James

Specifically, when I do this:
ADT_A08 msg = (ADT_A08)msg;
I get this error:

James,
Switching operating systems and rebuilding took up a lot more time than I had
expected. I am up and running now.
I am still getting the issue with that particular message being identified as
an ADT_A01 message.
I will be working on this all day (and for a good while now that I have my work
station up and running again).
Any ideas would be appreciated.
Thanks,
Garrett

James,
I think what you said at the end might be the problem. I do have the latest
version of HAPI, but I was using a test txt file to throw messages in.
I am switching my operating system today, and may be out of commission most of
the day if things do not go smoothly. As soon as I get up and running I will
try and confirm what the issue is.
At the end of the day yesterday, I did almost exactly what you have above
there, minus the:
parser.setValidationContext(new NoValidation());
But when I used the getVersion() method, it was saying that the message was an
ADT_A01 message.
Thanks and I will update ASAP!

Hi Garrett,
Hi Garrett,
Strange, I put your message into your code and it seems to work for me. The
following:
String msgString = "MSH|^~\\&|RAMSOFT|SENDING FACILITY|RAMSOFT|RECEIVING

GenericParser parser = new GenericParser();
parser.setValidationContext(new NoValidation());
Message msg = parser.parse(msgString);
System.out.println(msg.getClass().getName());
..parses correctly. Are you using the latest version of HAPI? Is it possible
you are reading from a file and getting the wrong line endings or charset or
something?

I started taking on an HL7 project about two weeks ago. The project was left
by the original programmer with very little documentation. Most of my time has
been spent doing research. I have successfully used HAPI to parse messages
from all of the version 2.x variants.
The problem I ran into, however, is what happens when someone has taken the
liberty to append a "custom extension" to a message. In particular, I am
having issues with a modified v2.3.1 ADT_A08 message that cannot be processed
by the same HAPI program that can process any other v2.3.1 message I throw at
it.
I downloaded the HAPI source code and have been digging, but I figured I would
shoot an email to the mailing list and see if any of you had any tips on this
type of issue.
Specifics about my issue:
I do get an error:
EncodingNotSupportedException
When using the GenericParser
This same program handles other HL7 v2.3.1 files smoothly. But this modified
ADT_A08 is the troublesome file.
Thanks!
Garrett
