== FHIR Example - CDI

=== Introduction

This is an example application of the `+camel-fhir+` component.
We’ll be using `+camel-cdi+` as well for an easy setup.

This example will read HL7V2 patients from a directory and convert them
to FHIR dtsu3 patients and upload them to a configured FHIR server.

=== Prerequisites

The example assumes you have a running FHIR server at your disposal. You
may use
https://github.com/HL7-DaVinci/test-ehr[hapi-fhir-jpa-server-example].

By default, the example uses
`+http://localhost:8080/hapi-fhir-jpaserver-example/baseDstu3+` as the
FHIR server URL, DSTU3 as the FHIR version and
`+target/work/fhir/input+` as the directory to look for HL7V2 patients.
However, you can edit the `+application.properties+` file to override
the defaults and provide your own configuration.

=== Build

You can build this example using:

[source,sh]
----
$ mvn package
----

=== Run

You can run this example using:

[source,sh]
----
$ mvn camel:run
----

When the Camel application runs, you should see a folder created under
`+target/work/fhir/input+`. Copy the file `+hl7v2.patient+` located in
the `+data+` folder into it. You should see the following output:

The Camel application can be stopped pressing ctrl+c in the shell.
