| == FHIR Example - OSGi |
| |
| === Introduction |
| |
| This is an example application of the `+camel-fhir+` component that can |
| be executed inside an OSGi container. We will be using Apache Karaf. |
| |
| The example assumes you have a running FHIR server at your disposal. You |
| may use |
| https://github.com/jamesagnew/hapi-fhir/tree/master/hapi-fhir-jpaserver-example[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 |
| `+org.apache.camel.example.fhir.osgi.configuration.cfg+` file to |
| override the defaults and provide your own configuration. |
| |
| === Build |
| |
| You will need to build this example first: |
| |
| [source,sh] |
| ---- |
| $ mvn install |
| ---- |
| |
| === Run OSGi / Karaf |
| |
| This example can be executed within Karaf 4.x |
| |
| To run the example, from the command line: |
| |
| [arabic] |
| . In the Karaf install root directory, start Karaf: |
| + |
| [source,sh] |
| ---- |
| $ bin/karaf |
| ---- |
| . Install the pre-requisites: |
| + |
| [source,sh] |
| ---- |
| karaf@root()> repo-add camel ${version} |
| karaf@root()> feature:install camel-blueprint camel-hl7 camel-fhir |
| ---- |
| . Copy the configuration file |
| org.apache.camel.example.fhir.osgi.configuration.cfg to the etc/ |
| directory of your Karaf installation: |
| `+InstallDir/etc/org.apache.camel.example.fhir.osgi.configuration.cfg+` |
| . Then install and start the example: |
| + |
| [source,sh] |
| ---- |
| karaf@root()> install -s mvn:org.apache.camel.example/camel-example-fhir-osgi/${version} |
| ---- |
| |
| When the Camel application runs, you should see a folder created under |
| `+work/fhir/input+`. Copy the file `+hl7v2.patient+` located in the |
| `+data+` folder into it. |
| |
| By tailing the log with: |
| |
| .... |
| ```sh |
| karaf@root()> log:tail |
| ``` |
| .... |
| |
| The following messages should be displayed: |
| |
| .... |
| ``` |

| Camel commands can be used to gain some insights on the Camel context, |
| e.g.: |
| |
| * The `+camel:context-list+` displays the Camel context: |
| + |
| .... |
| karaf@root()> camel:context-list |
| Context Status Total # Failed # Inflight # Uptime |
| ------- ------ ------- -------- ---------- ------ |
| camel-fhir Started 1 0 0 3 minute |
| .... |
| * The `+camel:route-list+` command displays the Camel routes: |
| + |
| .... |
| karaf@root()> camel:route-list |
| Context Route Status Total # Failed # Inflight # Uptime |
| ------- ----- ------ ------- -------- ---------- ------ |
| camel-fhir fhir-example-osgi Started 1 0 0 4 minutes |
| .... |
| * And the `+camel:route-info+` command displays route information: |
| + |
| .... |
| karaf@root()> camel:route-info camel-fhir fhir-example-osgi |
| Camel Route fhir-example-osgi |
| Camel Context: camel-fhir |

| Finally, you can stop the example with: |
| |
| .... |
| ```sh |
| karaf@root()> uninstall camel-example-fhir-osgi |
