Non-standard segments of a message are not shown

[biliboc]

Dear All,

I am pretty new in HAPI and I have this question:
Why do non-standard segments of a message are not shown?
Or, am I doing something wrong?

For instance, I added FHS segment to a DFT_P03 (like in the code sequence below) but when displayed I get this output (no FHS segment at all):

<DFT_P03 xmlns="urn:hl7-org:v2xml">
    <MSH>
        <MSH.1>|</MSH.1>
        <MSH.2>^~\&amp;</MSH.2>
        <MSH.3>
            <HD.1>CHARGER</HD.1>
        </MSH.3>
        <MSH.5>
            <HD.1>IDX_TES_CHG</HD.1>
        </MSH.5>
        <MSH.7>
            <TS.1>200702161541</TS.1>
        </MSH.7>
        <MSH.9>
            <MSG.1>DFT^P03</MSG.1>
        </MSH.9>
        <MSH.11>
            <PT.1>P^T</PT.1>
        </MSH.11>
        <MSH.12>
            <VID.1>2.4</VID.1>
        </MSH.12>
        <MSH.18>ASCII</MSH.18>
    </MSH>
    <EVN>
        <EVN.1>DFT_P03</EVN.1>
        <EVN.6>
            <TS.1>200702161541</TS.1>
        </EVN.6>
    </EVN>
</DFT_P03>

The code:

        ca.uhn.hl7v2.model.v24.message.DFT_P03 p03 = new DFT_P03();

        MSH msh = p03.getMSH();
        ((AbstractPrimitive)msh.getSendingApplication().getComponent(0) ).setValue( "CHARGER" );
        ((AbstractPrimitive)msh.getReceivingApplication().getComponent(0) ).setValue( "IDX_TES_CHG" );
        msh.getDateTimeOfMessage().getTimeOfAnEvent().setValue( TransformUtils.SDFD_YYYYMMDDHHMM.format( new Date() ) );
        msh.getFieldSeparator().setValue( "|" );
        msh.getEncodingCharacters().setValue( "^~\\&" );
        ((AbstractPrimitive)msh.getVersionID().getComponent(0) ).setValue( "2.4" );
        ((AbstractPrimitive)msh.getProcessingID().getComponent(0) ).setValue( "P^T" );
        msh.getMessageType().getMessageType().setValue( "DFT^P03" );
        msh.getCharacterSet(0).setValue("ASCII");

        EVN evn = p03.getEVN();
        evn.getEventTypeCode().setValue( "DFT_P03" );
        ((AbstractPrimitive)evn.getEventOccurred().getComponent(0) ).setValue( TransformUtils.SDFD_YYYYMMDDHHMM.format( new Date() ) );

        p03.addNonstandardSegment("FHS");
        FHS fhs = new FHS(p03, new DefaultModelClassFactory());
        fhs.getFileFieldSeparator().setValue( "|" );
        fhs.getFileEncodingCharacters().setValue("^~\\&");
        fhs.getFileSendingApplication().setValue("CHARGER");
        fhs.getFileReceivingApplication().setValue("IDX_TES_CHG");
        ((AbstractPrimitive)fhs.getFileCreationDateTime().getComponent(0) ).setValue( TransformUtils.SDFD_YYYYMMDDHHMM.format( new Date() ) );

        p03.addNonstandardSegment("FTS");
        FTS fts = new FTS(p03, new DefaultModelClassFactory());
        fts.getFileBatchCount().setValue("0");
        fts.getFileTrailerComment().setValue( "URA" );

        //instantiate an XML parser
        XMLParser xmlParser = new DefaultXMLParser();
        System.out.println(xmlParser.encode(p03));

Hi Constantin,

The only thing you need to change is to retrieve the nonstandard segment
from the message after you have added it instead of instantiating a new
one, as the message itself takes care of instantiating the new segment.

Basically, replace this line:
FHS fhs = new FHS(p03, new DefaultModelClassFactory());

With this one:
FHS fhs = (FHS) p03.get("FHS");

Hope this helps!

By the way, would you mind if I used your example code in the "HAPI By
Examples" section of the website I am working on?

Dear all,

I want to deactivate telephone field validation when using
PipeParser.parse() method.
I'm getting the following error:

ca.uhn.hl7v2.model.DataTypeException: Failed validation rule: Matches
the regular expression (\d{1,2}
)?(\(\d{3}\))?\d{3}-\d{4}(X\d{1,5})?(B\d{1,5})?(C.*)?: Segment: PID (rep
0) Field #13

Hi Constantin,

You can change the validation rules using
Parser.setValidationContext(). You will have to provide your own
validation.ValidationContext implementation with the rules you want.
See validation.impl.DefaultValidation for the defaults.

Hi James,

I am using a MFN_M01 message, my code is something like this:

MFN_M01 mf = new MFN_M01();
mf.getMSH().getFieldSeparator().setValue("|");
mf.getMSH().getEncodingCharacters().setValue("^~\\&");
...
mf.addNonstandardSegment("ZBN");
ZBN zbn = (ZBN) mf.get("ZBN");
zbn.getLocation().setValue("xxxxxxxxxxxxxxx");

I am getting the following exception though:
java.lang.ClassCastException: ca.uhn.hl7v2.model.GenericSegment

my ZBN class extends AbstractSegment (later I tried to change it to extends GenericSegment but both failed)

I am using v23.

Thanks,
