ServiceMix Kernel and Camel

Guillaume already announced the release of ServiceMix Kernel 1.0.0 on his blog. We use it as the base for building SMX 4, but you can add any behavior to it by just installing a few bundles.

An example: to convert ServiceMix Kernel into an Apache Camel route container, we just type these three commands in the kernel's console:

osgi install -s mvn:org.springframework/spring-tx/2.5.5
osgi install -s mvn:org.apache.camel/camel-core/1.4.0
osgi install -s mvn:org.apache.camel/camel-spring/1.4.0

This will get the bundles from a local or remote Maven repository, install and start them. Once this is done, you can just create a simple XML file containing the route definitions in the deploy and kernel's file monitor will install and deploy them. You can check the log file with the log d command to see the route in action.
