Apache Karaf 2.3.8 and 2.4.0 Released!

The Apache Karaf team are pleased to announce the availability of Apache Karaf 2.3.8 and 2.4.0!

Apache Karaf 2.3.8 is an update patch for Apache Karaf 2.3.7, containing several bug fixes, and dependency updates. We have introduced support of !$ to recall the last command argument, and improved the command description for osgi:shutdown. It is recommended that you review our release notes before updating your deployments.

Apache Karaf 2.4.0 release represents a new branch of Apache Karaf development. It includes the latest Aries and Pax libraries, Apache Pom 14, add support for role-based JMX authorization, includes heap dumps when we create debugging data from create dump command, blueprint-web feature, support for JAAS groups, and includes Pax CDI feature. There are several hundred items currently in this RC's release notes, so you'll want to spend some time discovering all the hidden gems.

As always, I'd like to thank the community for coming together to help make the Karaf release process one of the best in all of open source software.

New Apache Karaf book and up coming release candidates

Apache Karaf Cookbook is now available from Packt Publishing!

This past winter Johan, Heath, Achim, and I started our latest adventure writing Apache Karaf Cookbook for Packt Publishing. We're happy to announce that the book is finally available for order via Packt's website.
We've taken care to cram as many hints, tips, and experiences into its pages as we could.

Taking a look at our table of contents you'll find recipes for:

• Apache Karaf for system builders
• Turning Karaf into a Smart Router with Apache Camel
• Model Karaf into a Message Broker with Apache ActiveMQ
• Transform Karaf into a JSP host with Pax-web
• Distribute your Karaf applications across a clustered container with Apache Karaf Cellar
• Transmute Karaf into a web service container with Apache CXF
• Turbo-charge your Karaf applications’ persistence layer scalability with Apache Cassandra
• Manage Big Data on Karaf with Apache Hadoop

We hope the community benefits from our experiences, we've poured a lot of ourselves into this title. For more publications on Karaf please see our Instant OSGi Starter, and Learning Apache Karaf.

OpenDaylight Update:

The OpenDaylight port to Apache Karaf has been proceeding steadily towards a stable ecosystem wide build. Next week's Techicial Work Stream conference call will include an End-To-End Hands-on walk-through of ODL Karaf Features. I've copied in below the TWS meeting objectives as outlined by Madhu Venugopal:

"Due to multiple queries from various projects, we are organizing an end-to-end hands on walk-through on Karaf. This will cover all the way from

1. Writing the Karaf feature file on any project
2. Building the .kar
3. Loading the Karaf Container
4. Installing the built feature and Validation.

Time permitting, we will also be covering the Docker based Integration Testing & Sonar coverage. Mathieu Lemay & myself will be leading these topics.
We request at-least 1 representative from each of the projects participating in Helium to attend this session."

I strongly recommend all OpenDaylight developers and users attend this meeting, also any interested Apache Karaf community members as this is a great opportunity to see Karaf's many benefits being realized in a large scale project. Please see the meeting page for conference call details.
