Re: Questions about OSGi

Hi Sigmund, Yes that's the only reason. Internally in the OSGi framework everything is translated into the generic requirements and capabilities. So if you use the Wiring API to obtain the capabilities of a bundle [1] you get all of them using namespaces, including the osgi.wiring.package etc, bu

Re: Bundle with Require-Bundle did not use Bundle-ClassPath in Felix.

Hi SvS, I would file a bug with Felix [1] ideally with a small testcase attached. The most likely thing is that there is some typo or other malformatting issue. The Bundle-ClassPath is tested by the OSGi CT and Felix passes that. So the best thing would be a small testcase to reproduce it. Then it

Re: Questions about Karaf 3.0.0: JAAS users, groups, roles, and ACLs

Yeah, the RBAC support that's there now is quite pluggable. You can basically use anything to set the roles in the current javax.security.auth.Subject. Currently JAAS is one way to do it, but you can also do it using other technologies and/or use your own custom roles (instead of the Karaf built-in

Re: Role Based Security

I wrote a blog article about how RBAC for OSGi services in Karaf can be used: http://coderthoughts.blogspot.com/2013/10/role-based-access-control-for-karaf.html Currently all the roles are specified using Config Admin, i.e. via .cfg files in the etc directory. On the annotation support, I know th

Re: Is my karaf server fully started ?

Or alternatively you can also write an little OSGi bundle that talks directly to the MBean Server via ManagementFactory.getPlatformMBeanServer() and does whatever it wants to do when the desired state has been reached. BTW do note that when using this with Karaf 3 you need to provide login credent

Re: New security mechanism in Karaf 3.0.0

Hi Ryan, I'll look at it on Monday. AFAIK there are no special ACLs for the instance commands (at least not by default). So you might have possibly found a bug... Cheers, David On 20 December 2013 21:47, Ryan Moquin wrote: > Hi, I ran into a problem recently as I was working on some code where

Re: OSGi Compendium APIs

It sounds like you're manually adding a package to the system bundle exports without actually providing the package classes. Would it not be better to simply install a bundle that exports the package you need? That means that you don't need to manually edit config files etc... While it's generally

Re: Getting a "java.lang.SecurityException: Insufficient credentials.” error when executing various commands in Karaf 3.0.0

Hi Paul, This could be an omission on my part. When I worked on the command security I didn't really focus at the client command, but mainly worked with the bin/karaf command and SSH access. I can look into this. Would you like to file a bug for it? In the mean time, if you need the bin/client c

Re: Spec version implemented by Karaf 3.0.0

Karaf 3.0.0 is based on Apache Felix 4.2.1, which implements some functionality from the OSGi Core R5 spec, but that is not fully complete. AFAIK it does implement full OSGi Core R4.3 functionality. Best regards, David On 21 March 2014 16:30, asookazian2 wrote: > Which version of the OSGi spec

Can I use a Karaf Feature as my Maven dependencies somehow?

Hi all, Just wondering whether this is possible. I'm using a Karaf feature at runtime and want to make sure that at build time I'm picking up all the dependencies exactly like they are in the feature (i.e. same bundles at compile time as at runtime). So I was wondering is there a way to use a Kar

Re: bundle specific classloaders

Hi Doug, Would the classloader for a specific bundle help here? It would give you access to what the bundle can see plus what it contains itself. You can obtain the bundle's classloader in two ways: 1. The easiest way is via the Bundle Wiring. If you have a bundle object, you can call bundle.adapt

I think the service dependency to a service published by the same blueprint container will work if that dependency is marked optional.

Re: wiring

In general it is possible to have multiple versions of the same library installed, this is totally fine in OSGi and therefore also in Karaf. Depending on your import version range you are wired to one or the other. I just wanted to note that if you do an update of a bundle that this does not autom

Re: A very busy resolver

This seems more of a Felix Framework issue rather than a Karaf issue. What version of Felix is running Karaf? You might want to try switching to the latest Framework (version 5.2.0) as a lot of work has gone into the resolver recently... Cheers, David On 31 August 2015 at 20:04, Benson Margulies
