CXF DOSGI - Minimal Bundles required to provide JAX-RS feature
Hi,
Can anyone tell me what are the minimum bundles required to provide JAX-RS feature in DOSGi ? I don't really care for "OSGi Remote Services Specification" implementation. The 1.4.0 multi-bundle distribution<http://repository.apache.org/service/local/repositories/releases/content/org/apache/cxf/dosgi/cxf-dosgi-ri-multibundle-distribution/1.4.0/cxf-dosgi-ri-multibundle-distribution-1.4.0-dir.tar.gz> seem to have a lot of bundles most of which I may not be needing if I wanted to implement a REST service using JAX-RS. Are the other bundles such as ZooKeeper absolutely necessary ?
As a side note , is there an OSGified version of Apache CXF independent from DOSGi project ?
Thanks,
Nadir

I think with DOSGi CXF 1.4 you can simply remove CXF JAX-RS module if
you do not need it.

Yes, starting from CXF 2.6.0 all the modules are bundles

It is quite typical problem by playing with manual bundle configuration in Equinox.
Other important aspects are:
1) org.osgi.framework.system.packages setting shows that packages are imported from JRE
2) bundle start level: default start level should be updated to "1" for some equinox bundles (common and ds) and cxf bundles should be started before application once.

DOSGi contains the most consistent bundles set to be deployed in Equinox.
If community has enough interest, it will be nice to provide P2 repository with CXF bundles to build Eclipse RCP applications.

Andrei.

Thanks Chris,
I am using Equinox. I was using 1.3.1 Single-bundle Distribution JAR in my
project previously. Recently I upgraded to 1.4.0. I noticed it was
registering some services and exporting some packages that were
conflicting with other bundles in my application. So I decided to use the
Multi-bundle distribution. However there are just so many bundles in the
dist , most of which I don't even need and perhaps conflicts with other
bundles.
Anyhow , I have decided to create my own bundle using JAX-RS libraries
from CXF 2.7.4 and implement a whiteboard pattern similar to DOSGi
project.

Re: CXF DOSGI - Minimal Bundles required to provide JAX-RS feature
Posted by Christian Schneider <ch...@die-schneider.net>.
Hi Nadir,
what runtime do you use for OSGi? If you are just using OSGi on the
server then I recommend using Apache Karaf. We have cxf features for
Karaf that allow to install cxf very easily. I have a tutorial at
http://liquid-reality.de/display/liquid/2011/12/22/Karaf+Tutorial+Part+4+-+CXF+Services+in+OSGi
.
If you have a plain OSGi container like Felix or Equinox then the DOSGi
mutli bundle distro is the easiest way to start. There is no slimmed
down version for jaxrs though so you have to try to remove bundles and
see if it still works. You can use karaf though and check the bundles
installed there to get an idea which bundles you need. In karaf you need
at least the feature cxf-jaxrs.
If you use Eclipse RCP then again the DOSGi distro is currently the best
way to start. I will start an effort to create a P2 repo for cxf soon.
Then it will be much easier to install cxf in Eclipse RCP.
Best regards
Christian
