[Niederlander A. <ani...@uu...>]

Hi,

Thank you for the clarification and sorry for the misunderstood.
hapi version I use is very old.
Is it safe and easy to migrate to version 2.1?

Thank you for your help.

Re: [HAPI-devel] HAPI 2.1 and overriding validation

[Andrew B. <And...@rc...>]

Thanks Christian,

That solved my problem but I'm still curious about overriding the default validation, is it possible to override the predicate that is set in the DefaultValidationWithoutTNBuilder?  For example, for a specific segment, if I am interested in allowing a space in the TN field using the predicate matches(String), I find that the compiler continues to complain at the calling of the super.  Eg.

<code>
public class newValidation extends DefaultValidationWithoutTNBuilder{
@Override
        protected void configure(){
            super.configure();
            forAllVersions().message("ADT","A01").terser("MSH-6",matches(".*"));
}}
</code>

I get a compile time error about failing a primitive for date-time.

Is there an easy way to override the default primitive?

Many thanks for your help.

Andrew

Hi Andrew,
note that there is only a (primitive) validation for TN, not for XTN, in DefaultValidationBuilder.
And, there is the DefaultValidationWithoutTNBuilder for exactly the reason you mentioned. So subclass this builder instead.
Hope this helps

Hi there,

I have recently started using HAPI and am impressed by the amount of function in the toolkit.  I have been struggling for about a week with the correct way to override the validation and am hoping that someone on this list can help me.

I have a segment that fails validation for an XTN type (as I am out of the US), I would like to keep validation on but change the validation for this segment.  I realize that I can turn off validation for the message but am curious as to the best way to approach this problem.

I have tried the HAPI by example method of extending the DefaultValidationBuilder and overriding the configure method, however the first call to super overrides the rule that I have provided to the method.  I have also seen an example of extending the ValidationContextImpl (http://osdir.com/ml/medical.hl7/2008-07/msg00003.html), but this appears to be an older approach to the problem.

I would appreciate any help that can be provided to point me in the right direction.

Andrew

[Niederlander A. <ani...@uu...>]

Christian,

First, thank you for your quick answer.

I'm using the version 2.4 but the package of the CommonTS classe is :
ca.uhn.hl7v2.model.primitive

The version is more explicit in other package i'm using, for exemple :
ca.uhn.hl7v2.model.v24.segment.OBX

Did you have an other idea ?

Hi Jens,

Thank you for the response. Yes, you are right. In my case, I was trying to
do something smart with Maven, and there were some dependency conflicts
happening behind the scene.
For the benefit of anyone who googles this, please check if your
dependencies are not conflicting with each other.

[Jens V. <jen...@gm...>]

That sounds like your class path is kinda screwed. Are you running it from
a command line or from you IDE. I suggest that you take a look at
"java.lang.NoSuchMethodError"
- this is a pretty common exception and you should be able to find a lot of
help regarding this - e.g.

Are you new to Java?

[HAPI-devel] Error executing the handling multipe versions example provided on the HAPI website

[Suranga K. <sur...@gm...>]

Hi James / all,

I was trying out the example which James had kindly provided at (
http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/examples/HandlingMultipleVersions.html
).
I tried it using HAPI 2.1, but I seem to be getting an error from the line
"HapiContext context = new DefaultHapiContext();"

The error message is,

[HAPI-devel] Parsing an ER7 delimited string into a HAPI message results in incorrect data

[Suranga K. <sur...@gm...>]

Hi,

I'm using HAPI 0.5 jar to try and parse a string (ER7 format) to an ORUR01
object.

The string i'm using is,

MSH|^~\&|FORMENTRY|LOCAL|HL7LISTENER|LOCAL|20080226102656||ORU^R01|JqnfhKKtouEz8kzTk6Zo|P|2.5|1||||||||16^LOCAL.FORMID
PID|||3^^^^||John3^Doe^||
PV1|1|O|1^Unknown Location||||1^Super User
(1-8)|||||||||||||||||||||||||||||||||||||20080212|||||||V
ORC|RE||||||||20080226102537|1^Super User
OBR|1|||1238^MEDICAL RECORD OBSERVATIONS^99DCT
OBX|1|NM|5497^CD4, BY FACS^99DCT||450|||||||||20080206
OBX|2|DT|5096^RETURN VISIT DATE^99DCT||20080229|||||||||2008021

I parse this string into a ORUR01 message object using GenericParser as
follows,

Message message = parser.parse(hl7_String);

The parsing completes successfully, but for some reason, HAPI is unable to
identify the components of the newly created hl7 object. For example, the
hl7 string (shown above) has a pid.3 segment, but i'm unable to capture
them using the pid.getPatientIdentifierList() method. The same is true of
the obx.getObservationIdentifier() method.
Can someone please advise me as to what i'm doing wrong here ? I also tried
with PipeParser, but i'm afraid that the results are the same.

PS: I tried the same with an xml delimited message, and it works perfectly
fine....

[HAPI-devel] how to make encode method in pipeparser thread safe

[Thumu, K. S (GE Healthcare) <Kis...@ge...>]

Hi,
I'm using PipeParser and trying to encode in an highly concurrent scenario.
I'm getting MSH-1 segment as null. I could resolve the issue by generating a new object every time.

But is there a way I can make my encode(Object) method thread safe.

I'm using Hapi 1.2 and camel 2.9.2


Thanks in advance.

Thanks & Regards,
Kishore

Re: [HAPI-devel] Hapi connection with existing server

[Bartłomiej B. <b.b...@ph...>]

Sorry that I didn't response for so long. The approach with two servers 
and two clients is understandable. But still I have one thing in my 
mind- as you said:
"there is always data that flows back on that port, but it's an 
acknowledgement, or a response message if the original message was a 
query of some sort"

so basically let's have a scenario:
1. We have a server created.
2. We use hapi-testpanel to connect with that sever.

the hapi-testpanel "sending connection" is active - it's connected to 
the server. I can now from hapi-testpanel (client) send message and 
client will receive ACK message. As I understand hapi-testpanel (sending 
connection) is using in this situation:
sendAndReceive(msg);

but is there anyway that server can send msg to client (connection is 
established)? So it's like sending ACK but without previously receiving 
any message to server by client.
If anyone know how this can be done - please let me know.
Currently I'm using camel hl7 mina2 so maybe with mina2 it's even easier 
but if anyone knows a way to do this in hapi-hl7 or anything please 
share your knowledge.

HAPI 2.5? - well, the most recent HAPI version is 2.1.
Regarding Camel 2.5 (which is VERY old) - in Camel 2.11 you can inject a XMLParser into the DataFormat, but in Camel 2.5 you can't.
So instead you need to write your own Camel processor or a POJO, which calls DefaultXMLParser#render on the Camel body and put back the XML result.

Hi,
Can someone help me with conversion ER7 data to XML data

As of now I'm using

DataFormat hl7 = new HL7DataFormat();

Can someone suggest me with an equivalent class for HL7DataFormat which would convert my data to XML rather than to ER7(Pipe seperated).

Help would be highly appreciated.

Re: [HAPI-devel] Dealing with messages that have failed to escape delimiters

[Ian V. <Ian...@he...>]

I grabbed this code from the on-line source.  Pretty sure it is from Hapi 2.1, although I think I checked 2.0 and found this routine hadn't had changes.
 
As to a pluggable version, for me if the proposal that "a single escape character on it's own does not constitute an escape sequence and should not be removed from the message" is accepted, I don't need a pluggable version.  If however single escape characters continue to be removed from messages such that it cannot be determined that this has occurred, then I will need a pluggable version. The trickiest part from my end is that it's gone, and I can't tell.  Nearly every other case I have encountered where delimiter characters are not escaped (and I have seen them all), there has been some way to tell (except maybe the field delimiter, that one sucks to figure out).
 
In general I would recommend that there be test cases around the place (including bad behaviours) that decode then encode a message, segment or field, and compare the input to the output.  If they don't match, try to figure out if it is possible to make them match. Some cases may indicate that a bad sender can really stuff things up, and there is no fixing it.  These cases may be wise to mention in doco.  I have an substantial amount of compensation code for various fields and data types to try to help with unescaped delimiters, principally to try to get the field to look like what the data on the senders application screen looked like, and pass it on correctly escaped.  We seem to have a LOT of badly behaved vendors, and apparently no power to make them fix it.  There are some big names on the list to.
 
Thanks for your consideration.
 
Ian

>>> Christian Ohr <chr...@gm...> 05/09/13 2:08 >>>
Yes, proper escaping is an endless source of joy ;-) What HAPI version are you using, btw? 

I'll take a look at your code in the next few days if time permits.

When modifying existing functionality, we always face the problem of backwards compatibility. So for the past one or two releases, we rather added possibilities to plug in custom strategies of doing things while keeping the default, rather than changing 
existing behavior. 

So far, Escape is unfortunately very static, but for 2.2 we can think about making the escaping strategy pluggable just like other things in HAPI. Thoughts?

cheers
Christian



2013/9/4 Ian Vowles <Ian...@he...>


I have sent mails to the general list about this issue before, and the advice has helped me progress.

Then along comes another system that has slightly different behaviour.

In this particular case a system correctly escapes the HL7 delimiters EXCEPT the escape delimiter. This allows it to send field content like this (from an address):

1 \ 24 Smith \T\ Wesson Road

I was hopeful that since the single escape on it's own didn't form part of an escape sequence, that it might be preserved through the parse. This is not the case. The lone backslash 
is consumed in the process and disappears. I don't know how valid an argument it is to say it should be preserved, but if it isn't, I can't subsequently properly escape it to send to 
a downstream system.

Given that I had been dealing with HL7 for some time before I found HAPI, I had done some work previously on an encode / unencode routine. My own code couldn't cope with this one 
either.

I decided it was time to be brave, and dive into the HAPI code. Somewhere there had to be encode/unecode low level routines.
Up until I looked in the source, I had been creating a new ST object, and using it's parse and encode methods. Once I looked into the source I found the Escape class.

This updated version of Escape does the following:

Preserves escape characters that do not form part of an escape sequence
Permits the exceptional escape sequence case of \X000d\ to work when the escape character has been changed to something other than \
Adds extra HEX escaped code \X0D\ and \X0A\ because we see them here occasionally.
Test case code is also included at the bottom, including my now infamous "HATER" example :-). Test cases with lots of > < are there because we often do transforms between HL7 and XML, so we often look at these in additional test cases of the XML output produced.
What are my chances of this being adopted?
If not, how can I get my version to override the existing one?
Thanks
Ian

Re: [HAPI-devel] Dealing with messages that have failed to escape delimiters

[Christian O. <chr...@gm...>]

Yes, proper escaping is an endless source of joy ;-)  What HAPI version are
you using, btw?

I'll take a look at your code in the next few days if time permits.

When modifying existing functionality, we always face the problem of
backwards compatibility. So for the past one or two releases, we rather
added possibilities to plug in custom strategies of doing things while
keeping the default, rather than changing
existing behavior.

So far, Escape is unfortunately very static, but for 2.2 we can think about
making the escaping strategy pluggable just like other things in HAPI.
Thoughts?

cheers
Christian

[HAPI-devel] Dealing with messages that have failed to escape delimiters

[Ian V. <Ian...@he...>]

I have sent mails to the general list about this issue before, and the advice has helped me progress.
 
Then along comes another system that has slightly different behaviour.
 
In this particular case a system correctly escapes the HL7 delimiters EXCEPT the escape delimiter.  This allows it to send field content like this (from an address):
 
1 \ 24 Smith \T\ Wesson Road
 
I was hopeful that since the single escape on it's own didn't form part of an escape sequence, that it might be preserved through the parse. This is not the case.  The lone backslash 
is consumed in the process and disappears. I don't know how valid an argument it is to say it should be preserved, but if it isn't, I can't subsequently properly escape it to send to 
a downstream system.
 
Given that I had been dealing with HL7 for some time before I found HAPI, I had done some work previously on an encode / unencode routine.  My own code couldn't cope with this one 
either.
 
I decided it was time to be brave, and dive into the HAPI code.  Somewhere there had to be encode/unecode low level routines.
Up until I looked in the source, I had been creating a new ST object, and using it's parse and encode methods. Once I looked into the source I found the Escape class.
 
This updated version of Escape does the following:
 
Preserves escape characters that do not form part of an escape sequence
Permits the exceptional escape sequence case of \X000d\ to work when the escape character has been changed to something other than \
Adds extra HEX escaped code \X0D\ and \X0A\ because we see them here occasionally.
 
Test case code is also included at the bottom, including my now infamous "HATER" example :-). Test cases with lots of > < are there because we often do transforms between HL7 and XML, so we often look at these in additional test cases of the XML output produced.
 
What are my chances of this being adopted?
 
If not, how can I get my version to override the existing one?
 
Thanks
Ian

I still do lurk here. :) The nule.org site had some issues with a malicious
WordPress theme, but I'm planning on bringing the old site back up with all
the information on LightHl7Lib in a bit. It definitely approaches the
problem of working with HL7-like messages in a different manner than HAPI,
but it suits my needs and may suit yours. You can email me directly if you
try it and have issues.

Re: [HAPI-devel] Hapi connection with existing server

[Ian V. <Ian...@he...>]

I reckon we would all be in a lot of trouble if HAPI didn't parse out
repeating segments and groups.
 
So glad I took the time to learn about HAPI. By far the best adherence
to the HL7 standard I have encountered in my interfacing career.
 
Finding good how-to guides is sometimes challenging, particularly if
you are trying to learn about the standard AND HAPI at the same time.
 
I would also recommend having a go at parsing, as Rahul has, so that as
you start to learn what terrible things sending and receiving systems
that claim HL7 'compliance' can do. Then you will better understand the
fantastic effort the HAPI developers have put into this API. Obviously,
the first gotcha is people not escaping the delimiter characters, and
the other is (heaven forbid) they use the standard feature and change
the delimiters to something else.
 
Happy parsing! Or should I say HAPI parsing?
 
Ian

Senthil, your solution is very similar to Nule.org's LightHl7Lib.
https://www.thot.us/svn/nule.org_LightHl7Lib/trunk/

This approach has some benefits, but HAPI tries to solve an entirely
different problem.

Hi,
I was following example send multiple messages out (
http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/examples/SendLotsOfMessages.html
) and found out something like this:

        // Setup server to listen for incoming message
        int port = 8813;
        boolean useTls = false;
        HapiContext context = new DefaultHapiContext();
        HL7Service server = context.newServer(port, useTls);


        // We want to listen ADT^A01 messages
        ReceivingApplication handler = (ReceivingApplication) new
ExampleReceiverApplication();
        server.registerApplication("ADT", "A01", handler);
So I run the application and as far as I understand I have setup server
and a client application which will listen for ADT^A01 messages. Now I
want to create another application (let's say another client) which will
connect with that already created server and listen for ADT^A02
messages.

I found on documentation something like that:

"If you are wondering how to integrate HAPI into an existing server
application, this is probably the place. Create a class that implements
ReceivingApplication, then look at HL7Server and ApplicationRouter to
see how to get HAPI to listen for messages on a socket and pass them to
your ReceivingApplication."

But how should I use HL7Server and ApplicationRouter to connect with
previously created server? Maybe I'm missing something in the logic but
let's consider that one software already has running server and I want
to integrate with them to listen for messages special for my application
(like ADT^A02) - how to do this?
