Hi Julian,

Sounds like an interesting idea which could lead to some refinements and enhancements to Karaf.

In regards to signing, if you build bundles with bndtools (either using Eclipse or just using it with Maven) it has a plugin for signing bundles and creating an exported Jar.. it seems like looking into that could be helpful.

I think Apache Sling which is OSGi based might be helpful around what you are trying to do..

That's probably the best I can suggest.  I like the way web applications are handled in OSGi and Karaf seems like it would be a great base for this sort of thing.

Is this an open source or private initiative?

Hi all,


after several discussions in the #karaf Channel in Slack I wanted to bring this issue also to the list.


We are currently building a Framework which is like an “App-Store” where we provide a “Runtime” and a set of SPIs to code “Apps” against. This Is all web-based so the Apps are in fact a set of Websites (boring, oldshool, give us apps!).

But we also like to introduce later on an “App Store” and the ability to (dynamically) load / start new Apps or stop / uninstall them.

So, theoretically speaking, Karaf is a good fit as it already brings a lot of necessary functionality.


My question is a bit similar to Jaaps in [1]: Are there any (known) and ideally Open Source solutions of what we are trying to solve?


We would also need things like Signed bundles (see [2]), a separate process for Managing (or remote controlling) Karaf and so on.

And it would be nice to look at another project and see what one can use from there and what not.


Or do you have any general questions, ideas, hints for us on if this would work or if we should better forget about that?


Thanks already!
