Thank you Martin for the inputs.
Yes, it is issue with OBX-2 datatype filed, I tested through my stand alone
program by supplying OBX-2 data type as ST.
p.getParserConfiguration().setDefaultObx2Type("ST");//ISSUE
However, on the fly I have a listener which starts listening once my server
started. In this case my changes are not getting effected and facing the same
issue. And also I tried to disable my validations, either way my issue is not
yet resolved.
Following way I am trying to capture HL7 message and further to process:
1) My health device is producing HL 2.3, and also I am using hapi2.3 jars
as maven dependencies. following is my MSH:
MSH|^~\&|ABAXIS, INC.^piccolo
xpress^3.1.37^0000P26854||||20201121161056||ORU^R01||P|2.3|
2) I tried with disabling validations. And also I supplied ST for OBX2
type. Still I am getting the same issue.
//No Validation
context.setValidationContext((ValidationContext)
ValidationContextFactory.noValidation());
p.getParserConfiguration().setDefaultObx2Type("ST");//ISSUE
3) My listener will start as soon as the server starts and it waits for the
message to receive and process further. I kept my validation disabling in my
listener class and next level also.. Following is my snippet:
Listener.java
public class VitalsDeviceListener {
private static final Logger log =
LoggerFactory.getLogger(VitalsDeviceListener.class);
// change this to whatever your port number is
private static final int PORT_NUMBER = 54000;
// In HAPI, almost all things revolve around a context object
private static HapiContext context = new DefaultHapiContext();
@SuppressWarnings("unchecked")
public static void enableDeviceListener(String[] args) throws Exception {
try {
boolean useSecureConnection = false; // are you using TLS/SSL?
HL7Service hl7Server = context.newServer(PORT_NUMBER,
useSecureConnection);
//No Validation
context.setValidationContext((ValidationContext)
ValidationContextFactory.noValidation());
// You can set up routing rules for your HL7 listener by extending
the
// AppRoutingData class like this
hl7Server.registerApplication(new RegistrationEventRoutingData(),
new MessageHandlingAndACK());
hl7Server.startAndWait();
log.info("Listener is started, waiting for client message:" + "\n");
} catch (Exception e) {
e.printStackTrace();
}
}
}
This listener forwards the message to MessageHandlingAndACK class. In this
class also again I am disabling validation and ST supply to OBX2.
public class MessageHandlingAndACK implements ReceivingApplication {
private static final Logger log =
LoggerFactory.getLogger(MessageHandlingAndACK.class);
private static HapiContext context = new DefaultHapiContext();
@Override
public boolean canProcess(Message message) {
return true;
}
@Override
public Message processMessage(Message receivedMessage, Map metaData)
throws ReceivingApplicationException, HL7Exception {
//No Validation
context.setValidationContext((ValidationContext)
ValidationContextFactory.noValidation());
//context.getParserConfiguration().setValidating(false);
Parser p = context.getPipeParser();
p.getParserConfiguration().setDefaultObx2Type("ST");//ISSUE1: Piccolo
not sending mandatory data type for OBX
//Message hapiMsg = p.parse(receivedMessage.toString());
String receivedEncodedMessage = p.encode(receivedMessage);
log.info("****Incoming message:\n" + receivedEncodedMessage +
"\n\n");
try {
log.info("****ACK message from server:\n" +
receivedMessage.generateACK());
return receivedMessage.generateACK();
} catch (IOException e) {
throw new HL7Exception(e);
}
}
}
After doing this changes also, I am getting the same issue. I am not sure
whether I am applying my changes at right place or not. I tested this code
with sample client, but it is failing with actual health device. Please provide
your valuable inputs.
Thanks,
Dasari

The error message is a bit unclear

at

but I think it is not related to OBX-5 (as that is the VALUE field, which is
filled in in your message. You highlighted OBX-4)
Instead I think it's about OBX-2, the DataType field, which is empty.

Hi Martin,
Thanks for your inputs.
Yes, I am using hapi-2.3 base jar and hapi-structires-23. My device is sending
following way the MSH & OBX segments :-
MSH Segment:
MSH|^~\&|XYZ, INC.^3.1.37^0000A1234||||20201121161056||ORU^R01||P|2.3|
OBX segment:
OBX|1||2345-7^^LN^Glucose SerPl-mCnc||99|mg/dL|73 to 118|N|||F||||||Patient|
OBX|2||3094-0^^LN^BUN SerPl-mCnc||13|mg/dL|7 to 22|N|||F||||||Patient|
You mean OBX-5 (the highlighted portion) is empty? If this is correct, I need
to check with my health device provider.
Thanks,
Dasari

Hi,
It looks more like a bad message coming in. You should be able to see the
message when logging ca.uhn.hl7v2.raw[.inbound]
The error says that a required data field (OBX-5) is empty. Solution is to let
the sender fill it in.
Is the incoming message a hl7v2.3 message? If it is an other version then also
include the corresponding hapi-structures-v2X
