Hi Markus,

yes, correct, copy-paste mistake ;)

Hi,

IIRC have never seen "effective:=active" in the Provide-Capability section.
I only know about in the Require-Capability.

Are you sure this is required?
At least it works if it is missing for "provide".

Best regard,

JB,

I apologize for not being awake when this came through
before.

I just want to make sure that I am completely following
this. The
resolver is requiring that some bundle mentions the
service in a
Provide-Capability -- NOT that the service is actually
running?



The resolver looks at the bundle manifest. It runs before
they are installed
/ started, so it can't really look at if they are running or
not.



The service in question is provided by an 'old' OSGi
bundle that does
not bother to do a Provide-Capability for it; it's not a
service, just
a service launched the old-fashioned way.

Is there some thread you can point me to that offers
suggestions for
dealing with this? I would rather not have to go add
Provide-Capability manifest entries for all my

This could be done for karaf 4.1 with a new xsd.

Yeah, that's definitely the easiest way, you can easily
remove the

When you are using features XML with namespace 1.3
or 1.4, the feature
resolver uses the service enforcement. It means that
it checks the
service
capability in the bundles. The service requirement
is basically a bundle
that needs a service "A" at runtime. So the resolver
will check the
features
containing the bundle providing such capability
(exposing the service).
It's
what the effective:=active mean.

The corresponding MANIFEST header is:


osgi.service;effective:=active;objectClass=myService


On the other hand, the requirement header looks like:



osgi.service;effective:=active;filter:="(objectClass=aService)"



Unfortunately, in Karaf 4.0.3, 4.0.4, 4.0.5, the
service enforcement was
enabled for features xmlns 1.3.0 NOT for 1.4.0 (it
was a bug). This bug
has
been fixed in Karaf 4.0.6. That's why when you
upgraded from 4.0.4 to
   

Re: What does effective:=active mean?

[Guillaume Nodet]

Btw, if that's not sufficient, i.e. if some people have a need for
disabling only specific feature, please raise  a JIRA and I can add the
flag on the repository / feature definition for 4.1.

You can always disable service requirements globally by setting
  serviceRequirements = disable
in the etc/org.apache.karaf.features.cfg config file.

Hi Benson,

As a workaround, you can use the feature capability definition (and it

Since Karaf does not come to command level when this sort of thing
goes wrong, it is not obvious to me how to gain any insight into what
is wrong. The service reference itself is very strange;
'RosetteBundleWarmup' a DS reference like:

@Reference(target = "(component-name=name-matching)")
public void setWarmup(RosetteBundleWarmup warmup) {
this.componentWarmup = warmup;
}

and I don't see the component-name filter in the error message. It's

Hi Benson,

JB,

I apologize for not being awake when this came through before.


No worries, it was a joke ;)



I just want to make sure that I am completely following this. The
resolver is requiring that some bundle mentions the service in a
Provide-Capability -- NOT that the service is actually running?


Correct.



The service in question is provided by an 'old' OSGi bundle that does
not bother to do a Provide-Capability for it; it's not a service, just
a service launched the old-fashioned way.

Is there some thread you can point me to that offers suggestions for
dealing with this? I would rather not have to go add
Provide-Capability manifest entries for all my dynamically created
OSGi services. Is there an option in a cfg file or a feature.xml that
turns this back off?


An alternative to the bundle itself is to set the capability at feature 
level. The features XML can provide the capability (if the bundles don't):



  ...
  
osgi.service;effective:=active;objectClass=myService

Perhaps I can persuade BND not to list them as requirements.

Thanks,

When you are using features XML with namespace 1.3 or 1.4, the feature
resolver uses the service enforcement. It means that it checks the service
capability in the bundles. The service requirement is basically a bundle
that needs a service "A" at runtime. So the resolver will check the features
containing the bundle providing such capability (exposing the service). It's
what the effective:=active mean.

The corresponding MANIFEST header is:


osgi.service;effective:=active;objectClass=myService


On the other hand, the requirement header looks like:


osgi.service;effective:=active;filter:="(objectClass=aService)"



Unfortunately, in Karaf 4.0.3, 4.0.4, 4.0.5, the service enforcement was
enabled for features xmlns 1.3.0 NOT for 1.4.0 (it was a bug). This bug has
been fixed in Karaf 4.0.6. That's why when you upgraded from 4.0.4 to 4.0.6,
the feature resolver is now "active" for your features XML and check the
service enforcement.

JB

Since Karaf does not come to command level when this sort of thing
goes wrong, it is not obvious to me how to gain any insight into what
is wrong. The service reference itself is very strange;
'RosetteBundleWarmup' a DS reference like:

@Reference(target = "(component-name=name-matching)")
public void setWarmup(RosetteBundleWarmup warmup) {
this.componentWarmup = warmup;
}

and I don't see the component-name filter in the error message. It's
also new to me that DS @Reference is even visible to resolution at the
time that boot features are being resolved.

Re: What does effective:=active mean?

[Jean-Baptiste Onofré]

So, I will explain a new time (for the third time ;)).

When you are using features XML with namespace 1.3 or 1.4, the feature 
resolver uses the service enforcement. It means that it checks the 
service capability in the bundles. The service requirement is basically 
a bundle that needs a service "A" at runtime. So the resolver will check 
the features containing the bundle providing such capability (exposing 
the service). It's what the effective:=active mean.


The corresponding MANIFEST header is:


osgi.service;effective:=active;objectClass=myService


On the other hand, the requirement header looks like:


osgi.service;effective:=active;filter:="(objectClass=aService)"



Unfortunately, in Karaf 4.0.3, 4.0.4, 4.0.5, the service enforcement was 
enabled for features xmlns 1.3.0 NOT for 1.4.0 (it was a bug). This bug 
has been fixed in Karaf 4.0.6. That's why when you upgraded from 4.0.4 
to 4.0.6, the feature resolver is now "active" for your features XML and 
check the service enforcement.
