As we have decided to not build karaf on top of DS I also think that
installing DS by default is not a good idea.
If we make sure the user bundles will have the requirement for the DS
extender then karaf will give an early warning that DS is missing. So
that should be good enough in my opinion.

I'm not a big fan of that, cause actually blueprint isn't a default

Hi,
That's one of the reasons why I proposed to put the "scr" feature
in the default build of Karaf..
Because usually people forget or don't know they need to install
the "scr" feature.
I don't know if this has already been done or if there is a Jira
to track it?
Regards,
Morgan

OK, it’s official, I’m an idiot. You’d think I could have figured
that out on my own. I have a script that configures Karaf when I
upgrade. Since I’ve been using Blueprint prior to this I’ve never
had to install it before so I missed that. Thanks so much.
BTW, just want to tell everyone involved in both Karaf and
BndTools what a great job both teams have done. Truly excellent
work all the way around.

Hi,
did you also install the scr feature, and did you make sure it's
actually the required version ;)

Hi all,
I’ve been messing around with OSGi and Karaf for a bit over 2
years now. Technically I’m no longer a developer, although if
you want to get stuff done, sometimes you just have to do it
yourself. I’ve built a BAM (Business Activity Monitoring)
platform using OSGi (I wasn’t aware of Decanter when I
originally did this but it sounds very similar in many ways.
Looking more closely at that is a future).
To date, I’ve done everything using Blueprint which has
worked quite well but I thought it might be time to take a
look at DS to see where that might fit in. To get a feel, I
had BndTools create a component bundle and tweaked things a
bit so that it should run in Karaf 4.0.5 as BndTools appears
to be anticipating OSGi R6 support. I changed the build to
reference osgi.cmpn; version=5.0 for example.
When I deploy the bundle, the resolver complains about not
being able to satisfy the package requirement:
org.osgi.service.component - version [1.2-2.0). I’ve looked
at the manifest and verified that the package is actually
imported so I’m at a loss. The component code and actual
bundle manifest are shown below, for completeness. Any
thoughts on what might be going on would be appreciated.
Regards, Scott
