Real Introduction to Apache Karaf

Question

We are looking to use Karaf, but their introduction/quick start (main Karaf website) has almost nothing to say about deploying apps to the container - I know, amazing yet true. Anyone know of a useful introduction for someone completely new to Karaf? Thanks.

Answer 1

Here are some useful links:

• How to use Karaf console: http://karaf.apache.org/manual/latest/users-guide/console.html
• Christian Schneider has some useful tutorials as well: http://www.liquid-reality.de/display/liquid/Karaf+Tutorials
• Jean-Baptiste Onofre blog (search on Google)

Pay attention that Karaf 3 has slightly different shell commands, so make sure that you are pointing to the right Karaf or you learn how to translate Karaf 2.x commands to Karaf 3.

Answer 2

A google for keywords: java, osgi bundle, activator

will turn up examples of how to code for Karaf. For example: http://www.javaworld.com/javaworld/jw-03-2008/jw-03-osgi1.html?page=2

Also, after learning the keywords (OSGI and bungle) I noticed netbeans has a project type of "OSGi Bundle". How nice.

Answer 3

I guess you looked at the wrong places the, cause the user and developer dokumentation tells you that you either deploy your artefacts either by dropping in the deploy folder, by installing with osgi:install url, by adding/installing features and so forth. I really recommend RTFM, it's there. In case you still didn't find what your looking for ask the users mailing-list.
