[HAPI-devel] HAPI Parsing A04, A05, A08, A28 and A31 all as A01?

[Scott A. <sa...@bj...>]

I'm relatively new to using HAPI and I am having a rather troubling =
problem.  Quite a few different HL7 messages are being recognized as A01 =
messages.  I am unsure whether it is a problem with HAPI, a problem with =
the format of the HL7 messages, or a problem with my understanding of how =
to use HAPI.  I am currently using HAPI 0.5 beta.  Does anyone know how =
HAPI decides what message to create?

An example message (with fake data):

In the MSH segment, the Message Type.Trigger Event clearly specifies it is =
an A08, yet it gets parsed by HAPI as an A01.

A ran through the following message types: A01, A02, A03, A04, A05, A06, =
A08, A13, A28, and A31.  Only the A01, A02, A03, and A06 messages are =
recognized for what they are.  All other messages (A04, A05, A08, A28, and =
A31) are parsed as A01.

My code is similar to as follows (assume "msg" is a String variable =
containing the example message):

[pre]
PipeParser pipeParser =3D new PipeParser();
Message m =3D pipeParser.parse(msg);
if (m instanceof ADT_A01) {
    ADT_A01 a01 =3D (ADT_A01) m;
    String triggerEvent =3D a01.getMSH().getMessageType().getTriggerEvent()=
.getValue();
    if ("A08".equals(triggerEvent)) {
        System.out.println("Oops, this A01 looks like it should have been =
an A08!");
    }
}
[/pre]

Thanks for any insight you can provide,
