This documentation page covers the integration options of Camel with the Eclipse Kura M2M gateway. The common reason to deploy Camel routes into the Eclipse Kura is to provide enterprise integration patterns and Camel components to the messaging M2M gateway. For example you might want to install Kura on Raspberry PI, then read temperature from the sensor attached to that Raspberry PI using Kura services and finally forward the current temperature value to your data center service using Camel EIP and components.

Loading XML routes from ConfigurationAdmin
Sometimes it is desired to read the XML definition of the routes from the server configuration. This a common scenario for IoT gateways where over-the-air redeployment cost may be significant. To address this requirement each KuraRouter
looks for the kura.camel.BUNDLE-SYMBOLIC-NAME.route
property from the kura.camel
PID using the OSGi ConfigurationAdmin. This approach allows you to define Camel XML routes file per deployed KuraRouter
. In order to update a route, just edit an appropriate configuration property and restart a bundle associated with it. The content of the kura.camel.BUNDLE-SYMBOLIC-NAME.route
property is expected to be Camel XML route file, for example:

<to uri="mock:bar"/>

Deploying Kura router as a declarative OSGi service
If you would like to deploy your Kura router as a declarative OSGi service, you can use activate
and deactivate
methods provided by KuraRouter
.

<scr:component name="org.eclipse.kura.example.camel.MyKuraRouter" activate="activate" deactivate="deactivate" enabled="true" immediate="true">
<implementation class="org.eclipse.kura.example.camel.MyKuraRouter"/>
</scr:component> |
