SimpleServer routes data to the parser. You just have to write a
ca.uhn.hl7v2.app.Application that does what you want with messages,
and register it with the server. Hopefully that hint is enough to get
you going with the Application and SimpleServer JavaDocs, because I
don't have anything in the way of a tutorial.

Each message is handled in a separate thread, so there is no conflict.
They get processed sequentially in Responder.processMessage(...).

Not directly, but you might be able to use a stylesheet to transform
from 2.XML to CDA.

Re: [HAPI-devel] Converting A01 to A??

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

Hi Scott,

You found a bug, but it's easy to fix yourself. Mappings like this are
only supposed to be done with event types that don't have their own
structures (like A04), but A31 does. Go to the package
ca.uhn.hl7v2.parser.eventmap ... there are text files there with the
mappings (one for each HL7 version) ... just change the line "ADT_A31=20
ADT_A01" to "ADT_A31  ADT_A31". If you aren't comfortable with this,
another option is to make sure the structure is specified in MSH-9-3.

[HAPI-devel] HAPI Copy a Segment

[Barry-HAPI <jag...@ci...>]

Hello,
I'm trying to copy a whole segment (i.e. PID) from a message into a response
message that use exactly the same segment. Now, I copy all fields, one by
one, and it takes long time.
Do you know if I can copy a whole segment in a sentence.

Thank you in advance,

[HAPI-devel] Converting A01 to A??

[Scott A. <sa...@bj...>]

Is there any reasonbly simple way to convert an A01 into, for example,
an A31 if that's what it is?  HAPI parses messages like A31's into
A01's, which is fine, but it can confuse the heck out of other
developers if I send them an A01 when they are expecting an A31.  Would
be nice if I could convert it easily and just send them an ADT_A31. 
I've looked at using DeepCopy along with the getNames() and get(String
name, int rep) methods of Message, and could use them, but it gets ugly
because it can only copy segments, forcing me to write extra code to
deal with groups and repetitions. Anyway, I was hoping there might be an
easier way I'm overlooking.

Thanks,

[HAPI-devel] Conformance Profiles and ConfGen errors

[Mike D. <mdo...@co...>]

Hi All,

BTW, I'm new here but I've worked with hapi for a bit now.  Great tool!  
Now I'm getting started with conformance profiles as these seem quite 
useful as well.  Also, I've noticed the significant and very much 
growing community involvement in or around this project.  E.g.. HL7 
organizations, US Veterans Affairs, etc.   Congrats!

Currently, I'm having problems with the ConfGen tutorial.  I'm using 
Messaging Workbench 1.6.4.1 and
hapi-0.5beta.jar.  See exact error messages from console output below!  
Basically ...

1.  "ConfGen -t" generated an "Apache Ant:Exception".

2.  ConfGen's class generation resulted in a "ConformanceError" error.  
Files were generated but I suspect there would be problems if I were to 
use them.

Also, perhaps things work a bit differently in the newer Messaging 
Workbench but I wasn't able to complete the tutorial steps in the manner 
stated.  I was only able to pick HL7 2.5 structures but I was trying to 
use 2.3.1 for my testing.  Also, even when I picked an HL7 2.5 structure 
(e.g. ADT^A01), a structure tree does not display and you can't run the 
report.  To get around this, I opened the example "Wondercis Inbound 
ADT-ADT_A01.mwb" file that displays as "HL7 2.3.1".  From here, I simply 
ran the "XML spec" report and then saved to file.  The output looks like 
it might be an HL7 2.3.1 conformance file.  I.e.  It contained 
"<HL7v2xConformanceProfile HL7Version="2.3.1" ProfileType="HL7">" on the 
second line.  Would this make sense?  Is this is a proper conformance 
profile file that could be used by CodeGen?

Any would be appreciated!  Also, I'd be happy to provide updated 
tutorial steps if this is needed.

Thanks,
Mike

[HAPI-devel] Extended tutorial for hapi socket connection

[Florian W. <flo...@um...>]

Hello,

I'm new to hapi. After reading the tech_docs i still have some questions:

First of all  the problem I'm trying to solve with hapi: HL7 messages are 
received via a socket connection. Data should be extracted and converted - as 
far as possible - to the clinical document architecture format CDA.

1.) Could you please send me a tutorial or a HOWTO for using the SimpleServer 
in my own program and how to pipe the data read from the socket to the 
parser. I am happy with well documented source code.

1.a) what happens if messages arrive simultaneously and how can they be 
handled?

2.) is there a way to use the XML encoder to produce cda or do you know any 
other possibility.

Thank you in advance!!  yours,
Florian Wozak

[HAPI-devel] Failed validation rule

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

Hi All,
=20
I'm getting a "Failed validation rule:" exception (see at end of msg).  =
I've
tracked it down to a non-standard DT format; the sender is tacking on =
the
time (4 digits) after the date in the AL1 segment (AL1-6).
=20
So - is there any easy way to get around this?  Seems all I need to do =
is
trim the last 4 digits on AL1-6.  I'm using a HL7 server, very simple.
Bryan Tripp offered one solution, to
=20
construct an ApplicationRouter, and you can wrap the method:
public Transportable processMessage(Transportable theMessage)
... to edit the message string (theMessage.getMessage() contains the =
message
string). You could either delete MSH-9-3 or move it to MSH-9-4 in case =
you
want the contents. You will have to find it by counting delimiters.
=20
BUT - it's not clear to me how to go about doing this.  Would anyone =
have an
example?

In 0.4.3 there is a system property you can set to disable phone
number validation. I don't have the code handy but it should be
documented in the root TN class. In 0.5 there is extensive
customization for datatype validation ... see
ca.uhn.hl7v2.validation.ValidationContext.

Sure, you can do this, but you also need to include the source for the
message libraries, which aren't included in the CVS or in the
source_core zip file (we treat them differently because they are
automatically generated rather than hand written). You can get them as
separate downloads. If you have trouble getting this working another
option is to just update the original jar with your changed class
files.

Re: [HAPI-devel] HAPI Parser (v0.4.3) || Exception with blank Phone Number in PID

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

Hi Sarang,

The default behaviour is to validate against the HL7 telephone number
format (the string "()   -    " doesn't conform to this), but you can
configure all the validation rules that are used by a Parser. If you
want to do a lot of configuration you should construct your Parser
with a custom ca.uhn.hl7v2.validation.ValidationContext. But in this
case it's probably simplest to do this ...

ValidationContextImpl context =3D
(ValidationContextImpl)parser.getValidationContext();
List list =3D context.getPrimitiveRuleBindings();

... then dig through the list and replace the TN binding with
something that allows whatever you want to allow.

[HAPI-devel] HAPI Parser (v0.4.3) || Exception with blank Phone Number in PID

[Sarang M. <sma...@im...>]

Hi,

We are getting a DataTypeException
when parsing an ADT message,
which contains a blank Phone Number in PID segment.

The Phone Number actually contains
empty brackets with spaces: "|( )   -    |"

Exception Details (in PipeParser):
Error while parsing: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 #14.

Can't the HAPI Parser handle empty Phone Numbers ?

The problem is that, the parser returns a 'null' Message Object.
So we loose all the other valid fields also.

Is there any solution to this ?

We have tried both v0.4.3 as well as v0.5beta


Thanks,
-Sarang Malwatkar.

[HAPI-devel] Re: linefeeds and \.br\

[<fre...@sk...>]

Hi,

Some time ago, Alan reported the problem of handling linefeeds. I've 
added one line of code in Escape.java, as he suggested:

	seqs.put("\\.br\\", String.valueOf("\n"));

Then I met the following problem: on Windows, the line terminators is 
"\r\n" (CRLF), not simply "\n". I tried:

	seqs.put("\\.br\\", System.getProperty("line.separator"));

but this led to two additional issues:
- the method escape cannot deal with values of more than one character 
(easy to change);
- the "\r\n" value must be escaped before the "\r" one.

If you are interested, please see my attached patch (and search for tags 
"Fred").

From: Alan Shields <alan@bt...>
linefeeds and \.br\  
2004-07-27 04:13

 Hi all,
 After years of splitting my report text over several OBX messages 
 somebody just asked me to send a single obx with \.br\ to signify 
 linefeeds.
 
 At first I thought of replacing the linefeeds with \.br\ in my code, 
 unfortunately HAPI escapes the \ to give me, \E\.br\E\.
 
 In the end I added the following line to ca/uhn/hl7v2/parser/Escape.java
 seqs.put("\\.br\\", String.valueOf("\n"));
 
 which works a treat for my outgoing messages, though I haven"t tried it 
 to see what happens if somebody sends me a \.br\
 
 Is this a reasonable approach?
 Is it possible for me to indicate to HAPI that I want to insert an 
 escape sequence?
 Is there any reason anybody would NOT want HAPI to simply replace 
 linefeeds with \.br\ ?
 

 Cheers
 Alan Shields

Re: [HAPI-devel] ORC 7.2.1 problem

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

Hi,

In the encoded message the & is escaped, so that parsers do not
mistake it for a sub-component delimiter. In the message object (and
when another system parses it) the & will appear as &.

[HAPI-devel] ORC 7.2.1 problem

[Davide A. <dav...@if...>]

Hi to all

I have to made a messagge ORM^O01 with the field ORC 7.2.1 valorized and 
i think that the correct is this :

Q1D&0000,0000,0000

for example and i want to made this with this code:
 
message.getORM_O01_ORCOBRRQDRQ1RXOODSODTRXONTEDG1RXRRXCNTEOBXNTECTIBLG(nRepetition).getORC().getQuantityTiming().getInterval().setValue(Frequenza+"&"+rsPost.getString("Orario1")+","+rsPost.getString("Orario2")+","+rsPost.getString("Orario3"));

but in output i have this:

Q1D\T\0000,0000,0000

Why ?
is correct this semantic instead of my (ver 2.3.1)

Maybe it is not allowed by the HL7 V2.3.1 to send messages with an other

Re: [HAPI-devel] Charset encoding

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

Hi Marco,

You can set the inbound character set with the system property
"ca.uhn.hl7v2.llp.charset". The value defaults to "US-ASCII" and is
used directly as the second arg to the InputStreamReader constructor.
