Embedding Karaf in a Java application
Hi all,
what would be the easiest way to embed a Karaf instance within an existing
Java application?
- using/deriving from org.apache.karaf.main.Main?
- using PaxExam Karaf?
- something else...?
Ideally, I would like to just start an instance of my own Karaf distribution
(available as a Maven artifact in my own repository) and interact with it
(accessing/invoking bundles and services, for example).
best regards, Peter

Thanks JB,
I'll have a closer look at the Karaf Main and Bootstap classes.

Hi Peter,
If I right understood, you want to ship Karaf in your application, and
start Karaf with your application.
In that case, you can use Main or Bootstrap (in the main module).
Just be careful with the in/out stream (depending what you want to do
with the Karaf shell console).
Regards
JB

Re: Embedding Karaf in a Java application
Posted by Andreas Pieber <an...@gmail.com>.
OK I've missed that example. But I'm not quite sure if it's that
useful for paxexam-karaf. Typically your options section is pretty
minimal (compared to other exam tests). Therefore I'm not quite sure
about the use. In addition pax-exam starts the process always in a new
VM which might be neither what you like. If this is what you desire to
do you might want to give the various runners here [1] a shot.
Kind regards,
Andreas

Re: Embedding Karaf in a Java application

Thanks JB,
I actually already have my own Karaf distribution (sorry for being unclear
on that point) so I was mostly interested in the wrapping part.
Do you know if there are any nice examples of using the
org.apache.karaf.main.Main class (maybe Main.main() is the best one)?
Regarding PaxExam Karaf, I am already using it for integration tests.
I'm just wondering if that project supports running Karaf outside of a
JUnit context similar to the following PaxExam example:
https://github.com/tonit/Learn-PaxExam/blob/master/lesson-servermode/src/main/java/org/ops4j/pax/exam/servermode/SimpleServer.java

Re: Embedding Karaf in a Java application

Hi Peter,
I would create my own distribution of Karaf.
If you want to hide/wrap it in your application, Main could be a way to
achieve that.
Pax-Exam-Karaf is designed more for the itests.

JB
