This documentation page covers the integration options of Camel with the Eclipse Kura M2M gateway. The common reason to deploy Camel routes into the Apache 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.

Kura component is available starting from Camel 2.15. |
KuraRouter activator
The Bundles deployed to the Apache Kura are usually developed as bundle activators. So the easiest way to deploy Apache Camel routes into the Kura is to create an OSGi bundle containing the class extending org.apache.camel.kura.KuraRouter
class:
Code Block | ||
---|---|---|
| ||
public class MyKuraRouter extends KuraRouter { @Override public void configure() throws Exception { from("timer:trigger"). to("netty-http:http://app.mydatacenter.com/api"); } } |
Keep in mind that KuraRouter implements the org.osgi.framework.BundleActivator
interface, so you need to register its start
and stop
lifecycle methods while creating Kura bundle component class.
Kura router starts its own OSGi-aware CamelContext
. It means that for every class extending KuraRouter
, there will be a dedicated CamelContext
instance. Ideally we recommend to deploy one KuraRouter
per OSGi bundle. Keep in mind that KuraRouter implements the org.osgi.framework.BundleActivator
interface, so you need to register its start
and stop
lifecycle methods while creating Kura bundle component class.
Deploying KuraRouter
Bundle containing your Kura router class should import the following packages in the OSGi manifest:
...
Code Block | ||||
---|---|---|---|---|
| ||||
install file:///home/user/.m2/repository/org/apache/camel/camel-stream/2.15.0/camel-stream-2.15.0.jar start <camel-kurastream-bundle-id> |
Then finally deploy your router bundle:

Kura router base class provides many useful utilities. This section explores each of thosethem.
SLF4J logger
Kura uses SLF4J facade for logging purposes. Protected member log
returns SLF4J logger instance associated with the given Kura router.
