blueprintBundleContext => Invalid BundleContext
Dear Karaf Team,
I inject the BundleContext using the Blueprint reference ref="blueprintBundleContext". When I try to register a service to this context, I get the following exception:
java.lang.IllegalStateException: Invalid BundleContext.
As it was injected, how can it be invalid?
Cheers,
JP

Exactly, the container simply check the existence.

Good.
What is the main difference between injecting directly the string, or injecting an idref, just reference check ref existence before injection ?

Yes

Ok, good.
Which kind of Java parameter type is injected for id-ref ? String?

You can't inject a bean manager, but you can inject the id using id-ref="xyz", inject the blueprint container using ref="blueprintContainer" and then programmatically ask the blueprint container for beans (or eventually for the metadata). That's how you can leverage prototypes programmatically.

Guillaume,
Is there a way to inject a bean manager instead of a bean itself using Blueprint?

If you don't need to iterator through osgi services, you could use a simple <list> element instead.
The problem with using osgi services and references is that if the reference is mandatory, the blueprint context won't be started until the reference is satisfied, which can't happen since the the service will be provided by the bundle itself. However, it should work when using an optional availability instead.

Yes, you are right, not exactly meant for but it is useful :)
In fact I just wish to iterate through beans and call a method for each bean. What is strange is that it is possible among bundles but not within bundle :S

It's not what it's meant for, reference-list is supposed to give you all available services of a interface.
Not exactly a for each, or?

In fact I would like to use the reference-list as a kind of "for each". I don't know how to do the same thing using the bean.
Is there a syntax to do so?

Since you're referencing a bean from within the same bundle, it's probably best to reference the bean and not the service of it.
If you really want to use the service (which I don't understand why) you should configure Karaf to start the bundles in a synchronous way.

Dear Karaf team,
I would like to use a reference-list on a service which is exported in the same bundle. Starting the bundle blocks on the GracePeriod state.
Is there a way to use a service which is exposed within the same bundle?
Cheers,
JP

RE: blueprintBundleContext => Invalid BundleContext
Posted by CLEMENT Jean-Philippe <je...@fr.thalesgroup.com>.
Well, I tried several things and found that first injected BundleContext (via ref="blueprintBundleContext") works, but then all restart injects a context which does not work and gives an Invalid BundleContext exception.
I can't explain why it works only first - help!
