Re: [osgi-dev] Setting reference target in component

[Alain Picard via osgi-dev]

Thanks Tim. I had read that thread but didn't make the association. I think
my case falls between some of the described solutions and part of your
point in 2, a bit of redesign :)

Re: [osgi-dev] Setting reference target in component

[Tim Ward via osgi-dev]

This sounds like a variation on this question 
 asked a few 
weeks ago in the osgi-dev list.

In summary, there are a couple of ways to achieve what you’re trying to do, and 
using configuration admin may or may not be the best approach given that you 
want to request an instance which you directly control the lifecycle of. 
Hopefully the thread will give you the answer that you’re looking for.

Best Regards,

Tim

[osgi-dev] Setting reference target in component

[Alain Picard via osgi-dev]

 I need to configure some Component to be session scoped. I have followed
the article from Dirk at
http://blog.vogella.com/2017/02/24/control-osgi-ds-component-instances-via-configuration-admin/
which matches what I want.

But in my case the Component that configures the service is also the has a
reference to this service. I read a couple of SO about this (
https://stackoverflow.com/questions/47393876/dynamically-setting-target-property-in-osgi-reference-annotatation
and
https://stackoverflow.com/questions/21166070/osgi-declarative-services-filter-references-at-runtime)
but I'm struggling to figure out the best way to both specify a
configuration as per the 1st article and then set the target in my
component to the resulting instance (and/or getting a component
configuration and set the target for my service).

Thanks
Alain
