hl7api-devel Mailing List for HAPI

You are welcome.  Hope it was useful.

You don't really have much choice but to parse the message or you can't do any work on it in HAPI.  That's how IEs do it anyway.

If I recall correctly a singleton is a class that is available across the entire jvm, so if you intend it to handle all messages from lots of queues,  I'd think it might quickly become a bottleneck for messaging.  No expert in this but, from an integration perspective it would be more scalable and better from the perspective of different services stopping and starting for various reasons to be individually controllable like you can in most IE platforms.   Don't know what your platform is or anything though.

I have a follow-up question. The documentation says that HapiContext is not intended to be a singleton. Should it be fine to create one HapiContext in the singleton that I create to handle the incoming messages from my queue? It seems very inefficient to recreate the objects I need to send each message.

Thank you.

This singleton will be for listening to the single JMS queue. It will be a Spring bean, which is a singleton by default anyway. The fewer objects I have to recreate for each message, the more efficient it should be. Singletons are usually designed to be accessible by multiple threads, but in this case, it will only be the JMS listener that will access it.

The service that will create the HL7 messages to send to the JMS will create HAPI objects each time and will need to be thread safe since multiple users can send messages to the JMS queue simultaneously. Each user can send multiple messages in a block, and the messages have to stay in order.

It does seem a little inefficient to create HAPI objects, convert them to a string message, send it through JMS, parse the string back to HAPI objects, then send the HL7 message through LLP. But I think the JMS built-in capabilities to handle multiple messages and fail overs is better than anything I could design myself to send the messages more directly.

Thank you,

Thanks for the feedback, Mike and Stewart. I use JMS message queues in other parts of the application. I had thought of that as a possible design. I wanted to check that I wasn't overlooking an existing solution and reinventing the wheel.

Thank you,

Haven't used HAPI in the raw for a while now,  but I think it is focused on the serialisation of HL7, there is an MLLP Sender/receiver,  but if you want to write then to a queue, after  or before receipt/send,  you'd need to handle the queue yourself.  JMS or ActiveMQ/Rabbit etc.  There are tons of examples and libraries for all the major queue APIs.

My Java application uses HAPI to create HL7 messages. The messages are initiated by users, and multiple users can send messages at the same time. The current implementation creates text files. Simultaneous file creation is no problem. I need to change the design to send the HL7 message through LLP instead. I need a queue to hold all the messages that need to be sent. Before I go down this path, does HAPI have anything that already handles something like this?

Thank you,

Patrick R. Thomas

Yeah, sorry. It's been a very long time since I posted a question on 
HAPI FHIR and I couldn't find the forum. Then, there's the fact that I 
discovered that I had put totally bogus values into those fields which 
HAPI FHIR didn't catch in its parse, but refused to give them back when 
I asked for them. So, I fixed that and I'm working.

Again, sorry for the multiple screw-ups.

If I’m not mistaken, this is the mailing list for the HAPI HL7v2 library.
This code below looks to be using HAPI FHIR – different library.
See the get help section here for more info: https://hapifhir.io/

Incidentally, you are creating a new (empty) Patient object, then trying to fetch the name. It doesn’t have one because you haven’t set one.

This message is from an EXTERNAL SENDER - be CAUTIOUS, particularly with links and attachments.
________________________________
In the code below, I have an incoming Patient which has all the fields that interest me filled in (see debugger image, but if it doesn't come through, it shows that patient is filled out for name, gender, birthdate and address).

However, when I attempt to inspect gender and birthdate, these are null despite the API telling me they exist (which, of course, they do--see attached image). Note that I create a new Patient, named worthy, and experimentation demonstrates that my code below copies the name and the address successfully to worthy. It's just trying to copy gender and birthdate that result in null. If I stop at the lines with *******, patient.getGender() and patient.getBirthDate() return null.

There must be some very fundamental bit of understanding of which I'm completely ignorant.

Hi Russell,

You pasted some code, but I don't see a direct relationship with HAPI.

What class is 'patient'? If it isn't ca.uhn.... something, then i don't 
think anyone here can help you.

In the code below, I have an incoming Patient which has all the fields 
that interest me filled in (see debugger image, but if it doesn't come 
through, it shows that patient is filled out for name, gender, birthdate 
and address).

However, when I attempt to inspect *gender* and *birthdate*, these are 
*null* despite the API telling me they exist (which, of course, they 
do--see attached image). Note that I create a new Patient, named worthy, 
and experimentation demonstrates that my code below copies the name and 
the address successfully to worthy. It's just trying to copy gender and 
birthdate that result in null. If I stop at the lines with *******, 
patient.getGender() and patient.getBirthDate() return null.

There must be some very fundamental bit of understanding of which I'm 
completely ignorant.

   {
     worthy = new Patient();

     // name
     if( !patient.hasName() )
       patientTooThin( "name" );
     HumanName          humanName = patient.getNameFirstRep();
     List< StringType > givens    = humanName.getGiven();
     String             family    = humanName.getFamily();
     String             first = null, middle = null;

     worthy.setName( Collections.singletonList( humanName ) );

The short answer to your question is yes, through the use of terser.
Terser is very useful, and works well. Parse the message with a pipeparser,
create a terser on the message, use the get method. Your messages may
introduce challenges, that terser can overcome, but it can still end up
being a complex implementation which is potentially fragile if a change
occurs in format of the message.
If you are going to use terser, remember that printstructure is your
friend. If you have message structures which insert Z segments within
groups, and/or standard segments in non standard locations you may find, as
I have, that building custom message structures using hapi is worth the
effort. See the lengthy example below.

Hope this helps
Ian

Terse for ZAL-4 will find the first ZAL and show field 4? = 19937487
No, it shows the value from the second ZAL, because the first is in a group.

Yes, it shows the value from the first ZAL, because we specified the group

Terse for /NTE3 will find the segment shown as NTE3 in the printstructure =

Note how the non-standard segments (extra NTE segment and ZAL) push the
ORC, OBR and OBX segments out of the normal structure. As a result, it will
be almost impossible to deal with these messages without creating a custom
structure to accommodate the non standard segments in a repeating group.

Hi,

I am trying to determine if Hapi supports any Z segment type without needing to code anything new within Hapi?
Also I am trying to find the latest source code and version for download.

Thanks so much,
Mike

Does HAPI test panel require spefically the 1.6.1 java version or should it run on corretto xx/java 1.8?

I have tries it with a 1.8 and coretto 17 but its still complaining that is wants 1.6?

Tried the usual things like path to java and JAVA_HOME.

OK.  I installed a 1.6 and it fires up.

Question answered I guess 😊

Hello,

I need to create an ORU^R01 with a custom ZDS segment.  Basically: MSH + 
PID + ZDS + OBR + OBX.

Is there (an easy) way to create an ORU^R01 message with a custom segment?

I've seen the example for reading a custom segment here.

https://hapifhir.github.io/hapi-hl7v2/xref/ca/uhn/hl7v2/examples/CustomModelClasses.html

Thanks,
Mike

Hi everyone,

I was using the latest HAPI HL7V2 Parser and it doesn’t seem to throw any errors if I don’t add EVN or leave EVN.2 empty for example in an ADT_A01 message. 

Is this expected behaviour or a bug?

This is confusing, so can anyone give me an idea of what kind of rules for required fields/segments etc is enforced by HAPI HL7?

Thank you,

Anadi Kashyap

I'm attempting to build an HL7 Client using the Hapi Library.

Fortunately there are examples that show clearly what to do. See the
SendLotsOfMessages Example here:
https://hapifhir.github.io/hapi-hl7v2/xref/ca/uhn/hl7v2/examples/SendLotsOfMessages.html

Unfortunately when I run the code, a null pointer exception occurs:
java.lang.NullPointerException
at ca.uhn.hl7v2.app.Responder.processMessage(Responder.java:91)
at ca.uhn.hl7v2.app.Receiver$Grunt.run(Receiver.java:127)
at
java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515)
at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264)
at
java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128)
at
java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628)
at java.base/java.lang.Thread.run(Thread.java:829)

Curiously this does not occur when the code provided in
SendAndReceiveAMessage example is used, where a server is set up and a
client sends.

Debugging through the code the problem line is where an ApplicationRouter
is addressed. When just a client is used, this is not instantiated with
setApplicationRouter but this setter is used when the client is created in
the SendAndReceiveAMessage example.

How can a client be made to function without a server?

Thanks
Ian

Hi Greg,

Unfortunately I think you probably have the wrong list.

This mailing list is for HAPI HL7v2, which is a Java (not JavaScript)
library.

Cheers,
James

Greetings all,

I am somewhat new to Javascript and very new to HAPI so please forgive the naiveté of my question...

I am trying to develop Javascript code for use in a Rhapsody engine that will handle (loop through) multiple OBR/OBX groupings in an ORU_R01 message (HL7 v2.6). My goal is to add an OBX segment to each group if/when an OBX exists where OBX-3 = 2907 within the group. My code only seems to work on the first OBR/OBX group. In my troubleshooting I have found that using hapiMessageIn.numberOfSegmentRepeats only seems to work if the segment identified comes consecutively. For example with a message like...

MSH...
PID...
PV1...
OBR|1|...
OBX|1|...
OBX|2|...
OBX|3|ST|2907|...
OBR|2|...
OBX|1|...
OBX|2|...
OBX|3|...
OBX|4|ST|2907|...

...the countobr value from the following code block is 1, and the countobx value is 3.

...
var obr_exist = hapiMessageIn.segmentExists("OBR", 0);
if (obr_exist == true) {
      var countobr = hapiMessageIn.numberOfSegmentRepeats("OBR");
      // Loop through each OBR
      for (var r = 0; r < hapiMessageIn.numberOfSegmentRepeats("OBR"); r++) {

          // Get the OBX segment count
          var obx_exist = hapiMessageIn.segmentExists("OBX", 0);
          if (obx_exist == true) {
                 var countobx = hapiMessageIn.numberOfSegmentRepeats("OBX");
                 // Loop through each OBX and look for OBX-3.1 = 2907
                 for (var x = 0; x < hapiMessageIn.numberOfSegmentRepeats("OBX"); x++) {
....
          }
     }
}
...

With the countobr only being equal to 1 it never loops through/processes the second OBR/OBX grouping and therefore the output message will have the added OBX segment only in the first OBR/OBX group, like...

MSH...
PID...
PV1...
OBR|1|...
OBX|1|...
OBX|2|...
OBX|3|ST|2907|...
OBX|4|... (added OBX segment)
OBR|2|...
OBX|1|...
OBX|2|...
OBX|3|...
OBX|4|ST|2907|...
(no added OBX segment)

Is there an issue with my syntax/use of the numberOfSegmentRepeats that may be causing this? Is there a better method you can propose to handle this scenario?

Thanks in advance for your review and any suggestions you may have to resolve this issue.

Hi Guys,

By way of background, this is our first HL7 or HAPI project and we are successfully exchanging HL7 messages without encryption, HAPI is proving to be a great library. We can receive and send messages without issue. We now have to implement encryption.

I am hoping you may be able to help with an issue I am having setting up TLS encryption for sending and receiving HL7 messages using HAPI 2.3.

We have been provided a public key for encrypting messages we send. I added the key to our keystore which I can see we need to load using a CustomCertificateTlsSocketFactory, but how do I specify the key in the keystore to use for encrypting outgoing messages? Do we just setup the keystore with a single key which gets used by default?

Similarly for incoming messages, we have supplied our public key, but I can’t see where in the CustomCertificateTlsSocketFactory we point to the our keypair or alias and specify the keypair password? Do we extract the private key into a dedicated keystore?

I would really appreciate any help you guys may have with this as this is quite new to us.

TIA

Zoran

Love this progress. It’s really useful in my test environment.

I'd like to know the state of HAPI too.

 One more comment, I was able to jar the whole kit and kaboodle together and get that to run as well.  This was also JDK8 if that didn't appear anywhere in my comments.
Thanks again!

For anyone else who finds this conversation.. I think the issue may have been with the version of Java the testpanel was running against. Adding JNA as Randy did would be one solution, using an older JDK (e.g. JDK6) would be another. The testpanel is definitely known not to work currently on JDK 9+.
