Hi Ronald!
Here is some more background on what I am doing...simply reading in an HL7
v2.3.1 file and trying to get its components, like MSH segment information,
PID segment information, OBR segment information, OBX segment information,
ZU1 segment information, ZU2 segment information, etc.
I'm using HL7 v2.3.1 and it seems that these methods you kindly write about
>msg.getPATIENT_RESULT().getORDER_OBSERVATION().getOBSERVATION(n).getOBX()
to extract multiple OBX segments only exist for v2.4 and higher.
I then tried to move everything to v2.4 just to try to get the above line to
work
but it seems that the way I am getting, for example, the MSH segment like:
ORU_R01 oruMsg = (ORU_R01)hapiMsg;
MSH msh = oruMsg.getMSH();
causes a fatal runtime error regarding the casting mechanism(s) of HAPI v2.4
code:
java.lang.ClassCastException
Do you know the way that v2.4 code approves of for, say, getting the MSH
which does not violate this ClassCastException?
Thanks,
NovaMan
