--------------------------------------------
As Andreas said, we can also enhance and extend the CXF DOSGi implementation. We can talk with Sergey about that.

--------------------------------------------
Maybe we can take a look on the CXF DOSGi implementation and leverage it.

[jira] [Issue Comment Edited] (KARAF-823) Add DOSGi support for
Cellar

[ https://issues.apache.org/jira/browse/KARAF-823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13090825#comment-13090825 ]

-----------------------------------------------------------------
Please let me share what I had in mind. By dosgi I am referring to remote
services (as described in the osgi compendium chapter 13) and not to a
specific implementation (e.g. cxf dosgi).
Since cellar already provides a) a node discovery mechanism b) means to
dispatch events, commands to remote nodes and c) distributed memory (which
can be used as a remote service registry), I was thinking to implement the
specification (or at least a part of it) on top of cellar.
I also have thought about using an existing implementation like cxf-dosgi,
and r-osgi, but I think that they don't fit well because simply they are
build from scratch (from discovery mechanism to transport layer etc).
Regarding the implementation, what I had in mind is to implement a service
listener that will create a queue (hazelcast queue) for each interface of
the exported service. A ListenerHook that will register a proxy for each
imported service (service that is not found locally but is found remotely).
And the actual proxy that will dispatch remote service call commands (cellar
commands) to the appropriate queue. The rest are already provided by
celllar.
I have implemented the above and also some samples and I am currently
testing it. So far it seems to be working fine, it requires no configuration
(only a property to mark a service as remote), it automatically scales (if
you add more nodes that export the service it automatically load balances
the load etc) and does not introduces any other dependency.
I was thinking to commit it to trunk by the end of the week. wdyt?

--------------------------------------------
Agree with that. By CXF, I have more in mind if we want to pick up some implementations/codes.
It's clear that it's better to follow the OSGi spec.

if dosgi isn't worked on anymore does r-osgi (http://r-osgi.sourceforge.net/) look beneficial?

--------------------------------------
This feature would be really interesting; but please keep in mind that dosgi hadn't been touched for about a year and there are a lot of upgrades/cleanups required before it is usable again with the latest versions. I might not be true here, but this was my impression as I looked last.
