[HAPI-devel] some beginner HAPI questions

[Steve P. <st...@pr...>]

I'm new to HL7, so please bear with me.  I've been looking at HAPI as a
solution for a pilot we're building, and it seems to be a good fit.  =
We'd
like to use the SimpleServer with 1 application.  In other words, we're =
only
dealing with 1 client app that will send us HL7 2.2 messages (via host
address & port), to which we respond.  It looks like we can use the 0.5
beta. =20
=20
A few questions:
=20
Does anyone have a high level spec/overview for HAPI? =20
=20
Does anyone have any sample code the shows how to register a simple
application to the SimpleServer?
=20
I understand that there are unit tests for HAPI, but I couldn't locate =
them
in either
<http://prdownloads.sourceforge.net/hl7api/hapi-0.5beta_source_core.zip?d=
own
load> hapi-0.5beta_source_core.zip or
<http://prdownloads.sourceforge.net/hl7api/hapi-0.5beta_source_v22.zip?do=
wnl
oad> hapi-0.5beta_source_v22.zip.  Could they be elsewhere?
=20
To change the default delimiter, can I use
ca.uhn.hl7v2.parser.EncodingCharacters.setFieldSeparator(char =
newFieldSep) ?
=20
Any other suggestions on how to get started are most welcome.
=20
many thanks,
Steve Pringle

Re: [HAPI-devel] Query about a problem.. .. ..

[Nico V. <ni...@us...>]

Hi Latha,

Could you please share the hl7 message you're trying to parse ?

I guess that your problem is related due to the fact that the segments 
(OBX...) are part of a segment group.

Please check the readme.txt file in the HAPI cvs root folder for 
instructions on obtaining the source code for the generated classes.

Thanks a lot !

Regards

Nico

That's normal. HAPI re-uses the A01 structure for other messages
that have the same structure. You have to look at MSH.9 to get
the actual message type.

[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,

Re: [HAPI-devel] Query about an error..

[Nico V. <ni...@sk...>]

Hi Latha,

The problem is that there exists a class ED in the 
ca.uhn.hl7v2.model.v25.segment namespace.

I guess there's an error in the hl7 database (source from where these 
classes are generated) that causes this wrong ED segment class ...

Bryan, James, could you please verify ?

Thanks a lot !

Nico

Re: [HAPI-devel] HAPI to Dot Net

[Nico V. <ni...@us...>]

Hi Jay,

I'm afraid it won't be easy to port the HAPI java source code to .net.

You could give it a try with IKVM, but I'm afraid the software is not 
mature enough (yet) to deal with hapi ;-)

http://www.ikvm.net/index.html

fyi Microsoft is also working on HL7 software integrated in the new release 
of Visual Studio - see

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/hl7softfac.asp

[HAPI-devel] fixOBX5 enhancement

[<Fre...@cl...>]

Hi,

For the first time, I have to parse messages with repetitive OBX-5=20
fields. Unfortunately, the method Varies.fixOBX5 sets the data type of=20
only the first repetition of this field. Is there any reason for that?

I've quickly added these few lines of codes (not the best solution, but=20
I would avoid changing the code structure) and it seems to work:

    public static void fixOBX5(Segment segment) throws HL7Exception {
        try {
            //get unqualified class name
            Primitive obx2 =3D (Primitive) segment.getField(2, 0);
            Varies v =3D (Varies) segment.getField(5, 0);

            if (obx2.getValue() =3D=3D null) {
              ...
            }
            else {
                //set class
                Class c =3D ...
                v.setData((Type) c.newInstance());

                // What about repetitions?
*                Type[] obx5s =3D segment.getField(5);
                for (int i =3D 1; i < obx5s.length; i++) {
                    v =3D (Varies) obx5s[i];
                    v.setData((Type) c.newInstance());
                }
*            }
        }
        ...

By the way, wouldn't it be a good idea to make this method more generic?=20
For example, I also had to use a workaroud to build MFN M02 messages:=20
since version 2.3.1, the MFE-4 field is a variant, from which the=20
datatype is specified in MFE-5. I don't know if there are other similar=20
cases in the HL7 spec. Why not a generic fixFieldDataType method, with 3=20
parameters: the segment, the field to be set and the field specifying=20
the datatype?

[HAPI-devel] Query about an error..

[latha <la...@re...>]

=20
Hi,

I am Latha V working as a Software Engineer for reli e-marg Mysore. We =
are developing an application which is using HL7 standard. We are using =
the recent HAPI which we got it from sourceforge.net i.e =
hapi-0.5beta.jar. We have got the following error while trying to create =
the instance of the class PMU_B01.




Can't instantiate ca.uhn.hl7v2.model.v25.segment.CER

ca.uhn.hl7v2.HL7Exception: Class ca.uhn.hl7v2.model.v25.segment.ED does =
not inherit from ca.on.uhn.datatype.Type




We have solved the problem temporarily by editing the source code of =
hapi0.5beta.jar by doing the following modification in the file =
ca.uhn.hl7v2.model.v25.segment.CER.java




the line=20

this.add(ED.class, false, 1, 65536, null);=20

was replaced by the line

this.add(ca.uhn.hl7v2.model.v25.datatype.ED.class, false, 1, 65536, =
null);




as that has to refer to the class ED of the datatype package and not the =
class ED under segment package.




Can you please let me know if there is any other means of solving this =
problem otherthan modifying the original jar file?




Thanks & Regards=20

[HAPI-devel] Re: Parse: Want PID-3 String Value from SIU packet

[<twh...@th...>]

James, 

Yes, the structuring and path def make perfect sense - thanks for the info.  
My bad for not digging deeper before I posted. 

You wrote:
"To access the PID segment, use notation like:
terser.get("/SIU_S12_PIDPV1PV2OBXDG1/PID-3");" 

Is this returning a Segment object, or the string value one of the segment's 
fields?  Seems like the latter. 

What I really need help with is how do I get the string value either using 
terser or not. 

However, seemingly no combination of path information returns anything but 
null. 

PipeParser parser = new PipeParser();
Message message = parser.parse(sMessage);
Terser terser = new Terser(message);
String sMRN = terser.get("/SIU_S12_PIDPV1PV2OBXDG1/PID-3"); 

sMRN is always null; 


Beyond that, I tried all combinations of using Groups, PIDs, CXs, etc and 
still seem to come up empty handed - even if I had figured that out, it 
seems to be alot of jumping thru hoops to get a simple string value so I'll 
assume it's the wrong direction. 

Again, thanks in advance for your help, 

Tom 

James Wrote--------- 

Hi Tom, 

The SIU_S12_.. structure is actually a segment group. Chapter 3 of the HL7
spec defines the SIU messages as containing the following structure:
[ { PID [PD1] [PV1] [PV2] [{OBX}] [{DG1}] } ]
which basically means that the entire chunk of segments is optional (as
indicated by the surrounding [ ]) and can repeat as a group (as indicated by
the surrounding { }). 

To access the PID segment, use notation like:
terser.get("/SIU_S12_PIDPV1PV2OBXDG1/PID-3"); 

This long name actually maps to a HAPI class by the same name. 

Does this make sense? 

Cheers,

[HAPI-devel] Re: Parse Issue: Want PID from SIU packet

[<twh...@th...>]

Nico, 

Thanks.  Yes, I figured that out after I dug a little deeper. 

The problem I'm still having is how to navigate the structures to get the 
value, say what with an ADT packet I'd get by doing this: 

String sMRN = terser.get("PID-3"); 

I've tried numerous combinations, but may be simply missing on the path 
syntax or maybe I need to use other classes, Groups, Segments, etc to get to 
the actual string value(s) I need. 

What is the call sequence or path string to get() to return the MRN? 

Thanks in advance for your help, 

Tom

RE: [HAPI-devel] Parse Issue: Want PID from SIU packet

[<ni...@sk...>]

Hi Tom,

The reason why you get this exception is because the PID segment is part of a group (PATIENT) in the SIU_S12 structure.

You can easily see this in the message structure description in the hl7 standard doc.

If you don't have access to the hl7 standard doc you could download the hl7 conformance tool called Messaging Workbench which contains a list of the structures from

http://www.hl7.org/lib_admin/docs.cfm?dir=library/committees/conf&comm=conf

Re: [HAPI-devel] Parse Issue: Want PID from SIU packet

[James A. <ja...@ja...>]

Hi Tom,

The SIU_S12_.. structure is actually a segment group. Chapter 3 of the HL7=
=20
spec defines the SIU messages as containing the following structure:=20
[ { PID [PD1] [PV1] [PV2] [{OBX}] [{DG1}] } ]
which basically means that the entire chunk of segments is optional (as=20
indicated by the surrounding [ ]) and can repeat as a group (as indicated b=
y=20
the surrounding { }).

To access the PID segment, use notation like:
terser.get("/SIU_S12_PIDPV1PV2OBXDG1/PID-3");

This long name actually maps to a HAPI class by the same name.

Does this make sense?

[HAPI-devel] Parse Issue: Want PID from SIU packet

[<twh...@th...>]

Hi, 

HL7 2.3
HAPI 0.4.3 

Have been HAPIly consuming and processing ADTs successfully for 6 months.  
Great package. 

Am now adding SIUs (S12, S14, etc) to the mix. 

Was suprised when a simple call to terser.get("PID-3") blew up with the 
infamous "Can't find PID as direct child" exception. 

I debug and find that the terser has childNames such as MSH, SCH, NTE and... 

SIU_S12_PIDPV1PV2OBXDG1 

What is this?  What HAPI class does it map to? 

Do I need to use the SIU_S12.... string somehow in the terser.get() call? 

 From a quick review of the messages on this list, it appears so.  What I 
haven't been able to find is a document describing this notation and the 
reason for it. 

Is there a description doc available? 

Also, why when I get a SIU^S14 packet, does the same SIU_S12... childName 
show up. 

Thanks in advance for any insight or doc,

Thank you very much, Martin, I've found it. It's
looking not that much bleak now ;)

Yet another question. Bryan is saying that a
parser/processor for v.3 is not on his plate.
It looks like developers for HL7's Java SIG either
dragging their feet or have thrown a towel.
So do we have tools to work with HL7 v.3? Without
tools all those standards are very much interesting
stuff but only for academics. Which tools either on
the market or from the open source community would
your recommend for v.3?

Thank you, gents.

Cheers,
Iouri

[HAPI-devel] Automatic handling of unexpected segments, including Z-segments, in ER7-encoded messages

[Sydney H. <syd...@ni...>]

Hello,

In HAPI 0.4.3, HAPI is able to handle Z-segments. I have a simple profile 
with 5 segments (1 Z-segment) based on a ADT_A01 message: MSH, EVN, PID, 
PV1 and ZEN. When I do the transformation from a message based on this 
profile to ER7. I get only the "standard" segment (MSH, EVN, PID, PV1) but 
no trace of the ZEN segment.

Why is the ZEN segment not processed? How to make it work with the ZEN 
segment? Is HAPI handling segment groups?

Thanks
Sydney Henrard

v3 is in an ongoing ballot cycle. It is extended with new topics and 
codes etc. every few months.
However, parts of the standard are already 'Normative' (see 
http://www.hl7.org/v3ballot/html/welcome/environment/index.htm: menu 
items are colored: red=normative. See the legend below the menu).

Re: [HAPI-devel] Any plans for HAPI for v.3 of the HL7 standard?

[Iouri L. <iou...@ya...>]

Thank you, Bryan.

Gents, if might be offtop but can you please advise me
on the current status of version 3? To my knowledge
there was a declaration sometime last year that v.3
Normative Edition was set to be released in January
2005. Yet, now it is late September already and on HL7
official site (http://www.hl7.org/) all I see is ANSI
standards for v.2.5, 2.4, 2.3.1. As far as version 3,
it is only HL7 version 3 (Draft). Draft does not look
to me as a normative document or is it? Is the HL7
official site simply stale and therefore does not have
references to adopted Normative Edition or are we
again in balloting-counter balloting cycle? 

Cheers,
Iouri

Re: [HAPI-devel] current state of HL7.org conformance profiles

[Bryan T. <bp...@gm...>]

Hi Jim,=20

I guess the profile library never really caught on. Too bad. But all
the standard profiles can be generated using the Messaging Workbench,
and you can use the MWB to edit them starting with the standard ones,
to customize for your own interface. The on-line library was just
meant to be a repository for vendors' custom interfaces.

[HAPI-devel] Any plans for HAPI for v.3 of the HL7 standard?

[Iouri L. <iou...@ya...>]

Hi everybody:

First of all, I do apologize if this matter might have
been clarified some time ago. 

Bryan, are there any plans afoot to make HAPI work
with the nascent v.3.0 of the HL7 standard?

Cheers,
Iouri

[HAPI-devel] current state of HL7.org conformance profiles

[Jim K. <ji...@ho...>]

Hey All-

I was browsing through the mailing list archives today looking for some 
pointers on using validation and the profile capabilities in hapi.  From 
what I read, the infrastructure is there to conformance test messages, but 
the profiles needed to drive the conformance testing are not a part of the 
hapi distribution.

In one of Bryan's notes, he linked to 
http://hl7api.sourceforge.net/conf/conformance.html which indicated that the 
profiles used in the validation infrastructure come from the folks at 
hl.org.  The previous link contained a link to the message profile library 
instructions on hl7.org:
http://www.hl7.org/Library/Committees/Conf/HL7v2GlobalMessageProfileLibraryjan2003V3.pdf

So, hopefully, I followed the link to the library and found that it led to 
the web equivalent of a dusty, empty old room.  I searched the library for 
profiles and the site was only able to produce four (two ACKs, two ADTs).  
Does anyone know if that's all there is?  Without a complete set of profiles 
it seems the HAPI validator is pretty much like a car without gas.  If it 
turns out we have to produce the profile documents by hand, how is that any 
better than using the XSD and a SAX parser to validate messages before 
handing them over to hapi?  would it be possible to use the XSD itself to 
drive the hapi validator?

Thanks.

[HAPI-devel] RE: BHS/FHS/BHT/FHT !?!

[Jim K. <ji...@ho...>]

Hi Dan--

If you're generating the EDI/PIPE style messages, Bryan answered this 
question in the following post:

http://sourceforge.net/mailarchive/forum.php?thread_id=4527700&forum_id=4433

[HAPI-devel] Is there an special handling for the HL7 null value?

[Chris S. <chr...@ya...>]

I am new to HL7 and HAPI, but was wondering if there is any special handling
for the HL7 null value ("") in HAPI.  I am using HAPI 0.4.3 and HL7 2.4.

From the Health Level Seven Final Standard Version 2.4 chapter 2.7 we have,
“HL7 does not care how systems actually store data within an application.  When
fields are transmitted, they are sent as character strings.  Except where
noted, HL7 data fields may take on the null value.  Sending the null value,
which is transmitted as two double quote marks (“”), is different from omitting
an optional data field.  The difference appears when the contents of a message
will be used to update a record in a database rather than create a new one.  If
no value is sent, (i.e., it is omitted) the old value should remain unchanged. 
If the null value is sent, the old value should be changed to null.”

I am assuming that in Java the HL7 null value would be defined as:
public static final String HL7_NULL = "\"\"";
Is this correct?  When constructing a message from a Java object should the
message value be set to the HL7_NULL string where ever the Java field is null?

Likewise when applying an update should the HL7 message value be tested for
this  HL7_NULL string and then set the corresponding Java field to null?  If
the message value is null then leave the Java field as is and do not set it?

Thanks

Chris
