Re: General question about DOSGi

2017-10-23 Thread Jean-Baptiste Onofré 

Hi,

CXF DOSGi implementation is based on CXF and exposes OSGi services as REST 
service.

That's an approach for DOSGi, but it's not the only one.

In Cellar, you have another DOSGi implementation based on NIO/Hazelcast.
Another one is Eclipse RemoteService.

Each has pros/cons.

Anyway, the purpose of DOSGi is to provide remote service invocation. So, a 
service is exposed on a node and used remotely on another one. It should be 
transparent for your code (the only minor change is that the service that has to 
be exposed for remote call should contain exported.service.interface property).

use case.


Briefly, I want to code with Declarative Services with Karaf because i feel it's 
a more OSGi oriented way to define and bind services.
Furthermore, I want my OSGi framework to recreate a web page the user can 
interact with: CXF can easily be deployed in Karaf, so I felt like it was a good 
choice over the other alternatives (like jetty). I used RESTful services as 
well, just to have something well structured.
In a previous question, Christian suggested me to use DOSGi to fullly implement 
this scenario.

After the successful attempt, I read the following resources on the topic.

1) http://cxf.apache.org/distributed-osgi-reference.html;
2) https://github.com/apache/cxf-dosgi;
http://www.liquid-reality.de/display/liquid/2013/02/13/Apache+Karaf+Tutorial+Part+8+-+Distributed+OSGi;

Especially from the last one: It seems that DOSGi is used to let an OSGi 
framework B access to services located on a OSGi framework A. This is all good 
and dandy but in my scenario (Karaf + CXF exposing a REST service) where are the 
2 OSGI containers? I can see only one, namely the one on my laptop in localhost!


I'm sure I'm missing something, probably for my inexperience.
Can someone solves this question of mine?

Thanks!

Re: General question about DOSGi

2017-10-23 Thread francois papon 
Hi,

I'm confuse too, I see the many solutions :

DOSGi, CXF servlet with HttpService, CXF via blueprint, CXF via spring,
Camel component (Rest, CXF...)

Actually I'm trying all this solutions, I don't want to use Blueprint or
Spring, I prefere using Declarative Service and in this case I see
DOSGi, CXFServlet or Camel.

The question about DOSGi for me is, is it the best way for publishing
services if this services are not consumed by other OSGi services.

Sorry I don't have the response but I'm very interesting to have some
advices on this point :)

Re: Karaf git repo gone?

2017-10-23 Thread Guillaume Nodet 
The official repository is now
  https://gitbox.apache.org/repos/asf?p=karaf.git
or
  https://github.com/apache/karaf

This is unfortunate that all the links are broken.  Maybe infra can setup a
redirect...

Hi Seth,

I've copied in below email from earlier today on Karaf Dev email list:

"Hi all,

FYI, INFRA moved our git repositories (for Karaf "Container", and
subprojects like Cellar, Decanter, ...) on gitbox.

You have to update your local copies to reflect that.

If you have any issue in term of permission, please let me know.

Regards

Details are here: https://issues.apache.org/jira/browse/INFRA-15265

All repos have been moved.
See https://gitbox.apache.org/repos/asf/
Committers need to visit https://gitbox.apache.org/setup/ to link accounts.

Karaf git repo gone?

2017-10-23 Thread Seth Leger 
Hi everyone,

The Karaf git repo at:

https://git-wip-us.apache.org/repos/asf?p=karaf.git

appears to have been removed. Was this intentional? It makes tracking
down things in JIRA very difficult because all of the automated git repo
links are now broken.

General question about DOSGi

2017-10-23 Thread Massimo Bono
