Right, thanks. @Reference should really support a filter, not just for this
case.
Also, exposing local beans as services seems a clumsy way, just to be able to
use them in commands.

The karaf @Reference annotation is not only a special annotation. The karaf
commands are run completely independent of the blueprint container.
So the only way to use a blueprint bean from a command is to export it as a
service. As the @Reference does not have a filter you should use a specific
interface for this service that is unique.

Hi Achim
Right, I can still use the "old"-style with Blueprint. But all this code is
marked as deprecated.
So I'm desparately trying to find a solution using the "new"-style Karaf
commands, as the old-style will disappear.
I would not spend time on this, if it wasn't marked deprecated.
I could switch if BlueprintContainer.getComponentInstance("id") was fixed,
so I could use the ids as set in Blueprint cfg file.

Hi Martin,

As you are using blueprint anyway that shouldn't be much of a big deal.
The idea about the new command way is to not depend on blueprint for
Karaf internals.
The @Reference annotation is actually a karaf own annotation,
org.apache.karaf.shell.api.action.lifecycle.Reference
There is no filtering available on that annotation.

So far I could not find a way to do this in the new Karaf command
framework.
A command is now instantiated each time it is invoked.
It can use OSGi services (@Reference) but there doesn't seem to be
a way to set a filter for it.
I can access the BlueprintContainer (it's available as a service),
but not the beans by their name.
oh well..

In Karaf 3, a command can be defined in Blueprint as:
<command>
<action class="my.Cmd">
<property name="producerTemplate" ref="producerTemplate"
/>
</action>
</command>
where in my case "producerTemplate" comes from a CamelContext
created in the same Blueprint context.
Now in Karaf 4, how would I do the same, i.e. set the property?
