Re: Using a Redis connection pool from Karaf
Not sure what the exact usage of command-pool is, but given the stack trace, it could be that a class is loaded from its name (i suspect it comes from the configuration). In such a case, to make it work in OSGi, the correct class loader needs to be used, one can't rely on the thread context class loader, or even the current class' classloader, which may have no visibility to the package. It may require a fix in some code loading the class to behave properly in OSGi. 2015-04-28 13:31 GMT+02:00 Jurgen Voorneveld jurgen.voornev...@redsocks.nl : I couldn't get the Apache Commons Pool libary to load under Karaf so I tried rewriting the app to use BoneCP instead of HikariCP.

Re: Karaf 3.0.1 does not consider service ranking set by Blueprint
Seems to be an issue of the Aries Blueprint implementation. To me it seems that the reference to the service (A1 or A2) is set when the component (X) is created. It only takes those services into account which exist at that moment. If later on another service with a higher ranking is added, the reference is not updated. As a workaround I've created a class which is a service reference listener. When a service is added, the service, ranking and ID is wrapped in an object and put into a TreeMap. The wrapper object implements compare to ensure the correct ordering of the services. With this workaround it is possible to add and remove new services with different rankings at runtime.

Hi, did you think about upgrading to a newer release of Karaf, cause I think this issue might have been fixed with a newer version of Aries. regards, Achim 2015-04-28 16:13 GMT+02:00 jkraushaar jochen.kraush...@doubleslash.de: Seems to be an issue of the Aries Blueprint implementation. To me it seems that the reference to the service (A1 or A2) is set when the component (X) is created. It only takes those services into account which exist at that moment.

Re: Karaf 3.0.1 does not consider service ranking set by Blueprint
Hi Achim, I checked the release notes of Karaf. According to them, Aries Blueprint was updated in 3.0.3 to 1.4.2. I would really like to update to this version. Unfortunately some of our legacy libraries are incompatible with the updates of the JPA libraries in 3.0.3. :-( Regards Jochen -- View this message in context: http://karaf.922171.n3.nabble.com/Karaf-3-0-1-does-not-consider-service-ranking-set-by-Blueprint-tp4039991p4040042.html Sent from the Karaf - User mailing list archive at Nabble.com.
Re: Karaf 3.0.1 does not consider service ranking set by Blueprint
Blueprint will stay with the service it selected until this service goes away. So for example if you would stop A1 and start it again then blueprint would switch. This is obviously not what people expect when the ranking is used. So I would consider this to be either a bug or a good enhancement request. Can you open an issue at aries if there is none already? I can work on it. Christian On 28.04.2015 16:13, jkraushaar wrote: Seems to be an issue of the Aries Blueprint implementation.

Hi, Christian!
I tried your blueprint-authz bundle to to authorize in OSGi services and
found out in its code, that SecurityAnotationParser parses beans, so looks
for annotations in class. But in runtime AuthorizationInterceptor looks for
annotations in called method's declaring class.
As an OSGi service is an interface, we can get such a situation, that method
of a class would require athorization, but could not get it, if service's
interface would not be annotated with @RolesAlowed. It's a code example
below:
public interface EchoService {
//@RolesAllowed(admin)
public String echo(String message);
}
public class SimpleEchoService implements EchoService {
@RolesAllowed(admin)
@Override
public String echo(String message) {
String result = message;
return result;
}
}
@Command(scope = kb, name = echo)
public class EchoCommand extends OsgiCommandSupport {
private EchoService echoService;
public EchoService getEchoService() {
return echoService;
}
public void setEchoService(EchoService echoService) {
this.echoService = echoService;
}
@Argument(index = 0, name = message, required = true, multiValued =
false)
private String message;
@Override
protected Object doExecute() throws Exception {
return echoService.echo(message);
}
}
Calling echo command in karaf console in this case we will get an error
message with empty roles' list Method call interface
biz.lorien.umrp.kb.properties.EchoService.echo denied. Roles allowed are
[].
And it's OK with uncommented annotation @RolesAllowed(admin) in
EchoService interface.
I think, it's not the best way to duplicate annotations both in interface
and implementing class.
Perhaps, it's my incorrect use of blueprint-authz?
What do you think about it?
Thanks in advance!

There is one more thing you should look into. Quite often you will need
the authentication result in a place different from the place where you
do the authentication.
Passing the subject around is not very effective.
Luckily there is a quite unknown way in JAAS to do this:
AccessControlContext acc = AccessController.getContext();
Subject subject = Subject.getSubject(acc);
This allows to get the subject at any place in your code.
An even more convenient way if you use blueprint is to authorize based
on security annotations.
See the blueprint-auhtz module:

In such a case, to make it work in OSGi, the correct class loader needs to be used, one can't rely on the thread context class loader, or even the current class' classloader, which may have no visibility to the package. It may require a fix in some code loading the class to behave properly in OSGi. 2015-04-28 13:31 GMT+02:00 Jurgen Voorneveld jurgen.voornev...@redsocks.nl mailto:jurgen.voornev...@redsocks.nl: I couldn't get the Apache Commons Pool libary to load under Karaf so I tried rewriting the app to use BoneCP instead of HikariCP. Bone doesn't have this dependency. This appears to work. BoneCP does want to load. Unfortunately I also have a Redis database which also has the dependency on Apache Commons Pool. So I'm back to the same error just one line down in my code. It doesn't look like there are any alternative connection pool libraries for Redis. I want to be able to connect to my Redis db using a connection pool, anyone know how to do that?

Re: Karaf 3.0.1 does not consider service ranking set by Blueprint
What I wanted to express is that users naively will expect that blueprint will select the service with the highest ranking. Of course when reading the spec they will probably guess that service damping might influence this. Do you know if we are free to change the current behaviour or if the spec mandates to stay with a service that was selected once?

Re: Karaf 3.0.1 does not consider service ranking set by Blueprint
I can read the following in the osgi spec, section 121.7.11 The backing service for a reference proxy must not be gotten from the OSGi service registry until an actual service object is needed, that is, when an actual method is called on the proxy. If the backing service becomes unregistered, then the proxy must unget the reference to the backing service (if it had gotten it) and get another service object the next time a method on the proxy is called. If a replacement can be found immediately, the reference listener’s bind method must be called without calling the unbind method. Other threads that need the same service object must block until the ser- vice object has become available or times out. I could not find anything more in the spec. Anyway, I just find some meeting notes from the OSGi EEG meeting about this exact situation. The outcome was that there would be no rebinding in case of a higher ranking service coming. I suspect is it is changed, the TCK will fail to pass. 2015-04-28 17:24 GMT+02:00 Christian Schneider ch...@die-schneider.net: What I wanted to express is that users naively will expect that blueprint will select the service with the highest ranking.

Re: local-broker.xml at startup
Can you try, in featuresBoot, to do: featuresBoot=(...)(hermes-resource) I don't remember if we added boot features grouping on Karaf 2.4. By the way, aries-blueprint doesn't exist on 2.4. As I said, I will take a look later today. Regards JB On 04/28/2015 08:59 AM, sekaijin wrote: hello I, as much as possible, simplified my test.

Re: Karaf 3.0.1 does not consider service ranking set by Blueprint
It may not be what you expect, but thinking it is what no one expects seems a bit extreme to me. DS has the concept of greedy and reluctant references so you can specify which behavior you want. david jencks On Apr 28, 2015, at 10:26 AM, Christian Schneider ch...@die-schneider.net wrote: Blueprint will stay with the service it selected until this service goes away. So for example if you would stop A1 and start it again then blueprint would switch. This is obviously not what people expect when the ranking is used. So I would consider this to be either a bug or a good enhancement request. Can you open an issue at aries if there is none already? I can work on it. Christian On 28.04.2015 16:13, jkraushaar wrote: Seems to be an issue of the Aries Blueprint implementation. To me it seems that the reference to the service (A1 or A2) is set when the component (X) is created. It only takes those services into account which exist at that moment. If later on another service with a higher ranking is added, the reference is not updated. As a workaround I've created a class which is a service reference listener. When a service is added, the service, ranking and ID is wrapped in an object and put into a TreeMap. The wrapper object implements compare to ensure the correct ordering of the services. With this workaround it is possible to add and remove new services with different rankings at runtime.
