CDI
This section described how to add support of CDI, and embed a CDI container in Apache Karaf. It doesn’t describe how to develop CDI applications. See the developer guide for that.
Pax CDI
Apache Karaf supports different CDI containers by using Pax CDI.
Pax CDI is pre-loaded in Apache Karaf.
You can see now a set of new CDI features available:

CDI Containers
Thanks to Pax CDI, Apache Karaf supports multiple CDI implementation versions, and different CDI containers.
You just have to install the feature corresponding to the CDI container and version that you want to use.
Apache OpenWebBeans
Apache Karaf provides a ready to use feature for Apache OpenWebBeans.
The openwebbeans feature automatically install the Pax CDI features and the Apache OpenWebBeans bundles:
karaf@root()> feature:install http karaf@root()> feature:install pax-cdi-openwebbeans
JBoss Weld CDI container
Apache Karaf provides a ready to use feature for JBoss Weld.
The weld feature automatically install the Pax CDI features and the JBoss Weld bundles:
karaf@root()> feature:install pax-cdi-weld
