mllp | Minimum Lower Layer Protocol ) server implementation | Runtime Evironment library

I have an application that receives a HL7 message and sends back an acknowledgement response. I'm using Citrus with the Camel MLLP component to send this HL7 message. What I'm trying to achieve is to be able to read the acknowledgement to compare it.

I currently have a test with hl7Payload, a String variable with HL7 content. In my Citrus context I have:

We have been testing out the Google Healthcare API specifically with HL7 and as I've run through the tutorials I've hit a roadblock. I should mention that I have a fair bit of experience with Kubernetes and AWS, but not so much Google Cloud.

This step here is what is giving me trouble:

https://cloud.google.com/healthcare/docs/how-tos/mllp-adapter#creating_a_compute_engine_vm_and_sending_messages

When I attempt to send the message from the VM I do not see a response, and the logs in the pod show me the following error:

I'm just trying to make a simple HL7 MLLP client using node.js I made some code that creates connection with HL7 server via socket. It sends some data to server. Then it waits for some answer. For testing purposes I use HAPI TestPanel 2.0.1. So, I have an issue. When I send data using my script to HAPI TestPanel, testpanel don't anwser me. In the testpanel's log it says that my client has connected to it and than nothing. When I turned on a debug option in testpanel, Log says that testpanel recieved bytes from my client, end then nothing else. What is the wrong with my script? Can anyone help me?

Thank you!

Here is my script:

The HL7 flow uses MLLP adapter in BizTalk. There is also the Accelerator provided by Microsoft which can change the format of the HL7 message to an XML format for it to be processed.

When it comes to logging the HL7 messages, options available are storing it to the database or storing it to a file location by coding this as Pipeline Components.

Is it possible to store a copy of the HL7 message on a separate MSMQ queue so that other options for logging can be considered? If so, what would be the approach? I know there is the MSMQ adapter but with HL7, the appropriate adapter would be MLLP (For the Microsoft provided additional tools, namely BTAHL7)

I am currenty developing a camel route which reads from a netty4/mllp endpoint and store the hl7 message to a amqp queue.

This is my environment:

• apache-maven-3.3.9
• apache-karaf-4.1.1
• apache-camel-2.18.3
• apache-artemis-2.0.0

this is my pom.xml

I am trying to set up an mllp listener for hl7v2.x messages using camel.

My environment

• apache camel and components version 2.18.3

Also I would like to avoid the use of the HAPI library, as I prefer a custom parser for the received and generated messages. As my clients are each one using different versions of the standard and really different fields usage.That's why there is no unmarshalling to the hl7 datatype in the following route, just to string. I'll do the parser myself.

And my route (all the beans and variables are defined elsewhere in the code, I think they are not relevant)

I want to create a HL7 listener in camel and process the HL7 messages I receive. I was planning to use SpringBoot/dropwizard along with camel for this purpose. The reason dropwizard is already used in my company for creating restful API's and I thought of reusing them for creating Camel routes as microservices also. My questions are,

1. HL7 messages are received using MLLP(Mina or Netty) over TCP. There isnt any HTTP involved. So is there any purpose of using a server like Jetty? Is it better to use Camel standlone?

2. If there is not any HTTP requests/listeners involved in my camel application, is there any use of me going for dropwizard/Springboot, as these frameworks were mainly created for creating Restful API's i.e for HTTP traffic?
